Demystifying Part 5: The Fender Mute

After a years-long hiatus, the Demystifying series is back!

First, I need to say thanks to all of you that have checked out the blog, and in particular the many that have shared and reposted these articles. Because of their popularity, Premier Guitar recently asked me to write an offset guitar setup guide for publication, which you can find in the May 2017 issue. AVAILABLE NOW IN STORES AND ONLINE!

So thanks to all of our readers, customers, and friends––without your support, this never would have happened.
The one bit of hardware I’ve not discussed previously is often thought of as a vestigial, an hold-over from a different time fit for the bin. Ultimately, it’s up to you if you’re ever going to use the thing, and to be honest, it seems like many don’t. However, if you’ve ever been curious about it, or if you use it but find it problematic, then friend, I come bearing glad tidings. I am of course talking about the Fender Mute.

A feature shared by both the Jaguar and Bass VI – though not across all models or years of production – this curious metal plate was originally intended to be a surrogate for palm muting. Couldn’t be a simpler mechanism, really: the mute is secured to the body by two screws, and the long bolt in the middle pivots on a spring-loaded plunger sunk into the guitar body. The mute can be engaged by pressing on the plate, shifting it back and forth in place, causing the foam pad to make contact with the underside of the strings.

The Fender Mute leaves the player’s picking hand totally free for strumming or sustain-less leads. This gives the device a sound distinct from traditional palm muting techniques, one widely used on instrumental surf recordings of the 1960s. What’s it sound like? I just happen to have an example for you here:

Like the Fender offset bridge, the mute requires some extra thought to set up correctly. Really, the whole procedure comes down to balance; the mute has to be set to engage smoothly while allowing the bridge to be lowered enough for playable action. If the mute sits too high, the bridge will rest on its mounting screws. Too low, and the mute won’t engage at all.

It’s best to begin with the mute installed on its own––leave the bridge for later. Remember those two mounting screws I mentioned earlier? You’ll need to find the lowest possible setting for them where the mute still pivots. Try screwing them in all the way, then backing off until the foam side of the mute pops up and stays put. Then, install the bridge and make sure it doesn’t sit on top of the mute mounting screws.

It may take a few tries, but you’ll soon find that balance. When pressing on the plate, the foam side should rise up to meet the strings but not push them up, then stay firmly in place. Pushing down on that side should disengage the mute, again with a firm action. If the mute doesn’t stay in place, or is difficult to move, take the bridge off and keep adjusting those mounting screws.

Top: disengaged. Bottom: engaged

It’s worth noting that, In order to get the mute set up correctly, your guitar will need to be shimmed as described in part two of the Demystifying series. A sufficient amount of neck angle is crucial, otherwise there may not be enough room under the bridge for the mute to be functional.

One problem that can crop up with the mute is that it pulls the strings sharp when it’s engaged. Often, this can be due to the mute sitting too high, which effectively shortens the scale length of the instrument. If that’s the case, cranking down the mounting screws should solve this issue for most players. Too-hard foam can also be the culprit, pushing up on the strings and raising pitch. Substituting a softer piece of foam here can work wonders (more on that later). Alternatively, one can easily shave off the bit of foam that touches the strings.

If you have a vintage Jaguar or Bass VI, you’re likely familiar with a problem that arises when the original foam on vintage instruments, due to age or contact with sweat: deterioration. This happens to pickup foam as well, where it hardens and compresses, rendering pickup height adjustment difficult or even impossible.

Hardened, sticky mute foam on a refinished ’63 Jaguar. You can see the gooey residue on the low E side of the mute.

If this happens to your mute foam, I have to tell you there’s no point in trying to salvage it. Touching or removing the stuff, you’ll notice that what was once foam is now a slightly gooey, sticky mess. Even on a totally original ‘60s guitar, leaving foam in this state is at the very least off-putting and potentially problematic, what with the black residue left behind on contact with skin or strings. Seriously, that stuff is disgusting.

Do yourself a favor and replace that foam. I’ll admit, it’s often the only part we’d even thing of replacing on a perfect vintage Jaguar. Replacement Fender foam can be found on eBay, but it seems that every parts supplier is out of stock right now. In a pinch, we use this. The link will take you to some weather stripping foam that’s just slightly taller than the 3/8” by 1/4” Jaguars have from the factory, but it should work like a charm. If the extra height concerns you, the same brand has a version with a height of 3/16″ as well.

Interestingly, this Mute wasn’t Fender’s first shot at string-dampening technology. Earlier, there was foam stuffed under the bridge covers of ‘50s Precision basses. The first Jazz Basses featured stiff pads for each individual string, while the later Mustang Bass  bridge had similar devices. Muting may make a bit more sense on bass than guitar, but give this mute system a shot and see if you can’t make it work for your brand of music. To the author, it’s a fun sound that makes some rhythm parts more interesting, and with effects added, it can bloom into something totally unique. And weird. Definitely weird.

Demystifying the Fender Jazzmaster and Jaguar Pt. 4: Pickup Lines

Of all of the things that cause confusion about these guitars, perhaps the most common misconceptions about Jazzmasters (and to a lesser extent, the Jaguar) surround the pickups. Because they’re so odd-looking and unfamiliar, people have all kinds of crazy ideas about what exactly is going on under the cover. I mean, it’s not often that most players have occasion to dismantle a vintage Jazzmaster guitar for the sake of exploration, so the befuddlement is understandable.

You know what’s not helping, though? Fender. God bless ‘em for introducing more and more models these days with non-standard pickup complements – a qualified win for modders and players seeking variety. Their current offerings are rife with sounds not normally associated with offset guitars, and for all of the faults a few of them have, Fender’s really woken up to the notion that offset guitars are cool. This is good.

Because Fender’s introducing so many new models with different pickups, the result is that there’s more confusion than ever about what you’re actually getting when you buy a Jazzmaster. Single-coils? P-90s? Wide Range Humbuckers? High-output ‘buckers? Yeah, they’re all there now, and some are hidden under Jazzmaster pickup covers. Go to Fender.com and type ‘Jazzmaster’ into the search bar, and you’ll get an army of models that have little in common with one another save for the body shape. Holy hell! How’s a girl or guy to keep all of that straight?!

In this article, we’ll try to do away with some of the misinformation and show you exactly what’s under the hood in both the Jazzmaster and Jaguar as well as some of the variations you’ll find out there in the marketplace. We’ll also dive in to some definitions and specifics so that you can make an informed choice when you go to buy your next offset guitar.

Compare this shot of Mojotone’s Jazzmaster pickup with that of the Strat pickup below.

Open Coils

The Jazzmaster pickup is a true single-coil pickup. From start to finish, these units are made of one coil of wire turned around the pole pieces, and in principle works just like those found on Fender’s more popular models, the Stratocaster and Telecaster. The construction of Jazzmaster pickups does have some notable differences when compared to other more common single-coil pickups: whereas a Stratocaster pickup is about 7/16” tall and wound tightly to the rod magnets, true Jazzmaster pickups are 1/8” tall and the windings extend nearly to the edge of the 1 1/2” bobbin.mojotone-classic-stratocaster-electric-guitar-pickup-single-strat-

This wider surface area translates to a wider frequency response (since the coil itself covers a far greater area of the string’s vibrational length) and, because the wire travels father with each turn, a hotter pickup. (Jason Lollar does a brilliant job of explaining this on his website) The Jazzmaster unit also uses rod magnets just like a Strat or Tele, differentiating it from a P-90, which it most certainly is not.

Don’t Drop the Soap[bar]

DV019_Jpg_Regular_306915.715_cremeOften, you’ll hear people refer to Jazzmaster pickups as ‘soapbar’ pickups, and they should be forgiven for doing so; that big, white cover certainly has a soapy quality, especially on older models where the covers have a more satin finish than shiny new parts. This really is erroneous as pickup nomenclature goes, as the term began its existence as a way to help distinguish between two varieties of Gibson’s P-90 pickup design of the mid-1940s, the other being the “dog ear” mounting style which is commonly found on Les Paul Jr. and 330/Casino guitar models.

The P-90 “Soapbar” is a P-90 pickup which has a rectangular shape with rounded edges and with both the pickup and mounting screws contained within the coil bobbin. Wikipedia mentions that the nickname probably came about with the introduction of the Les Paul model in ’52, on which the pickup covers were white. These, of course, looked like bars of soap to consumers, and thus the name stuck. (Funnily enough, the Jazzmaster pickup looks more like a bar of soap to me than P-90s, but I digress.)

If we’re just talking about the covers, the Jazzmaster pickup’s very mounting scheme differs from the definition of the term ‘soapbar’, but again, that’s such a slight difference that there’s no shame in having used it. I mean, what matters is what’s inside, not where the screws mount, right?

To be clear, standard Jazzmaster pickups are NOT P-90s in both design and intention: the P-90 uses bar magnets beneath the coil, which magnetizes the pole piece screws and imparts a louder, midrange-focused personality. P-90s are also wound tightly around the bobbin and usually have hotter output, with most vintage examples in the 8-9.3Kohms output range. Jazzmaster pickups use rod magnets, generally live in the 7.4-8.4 range. Not a big difference, but notable.

The louder, dirtier sound of a good P-90 contrasts with the Jazzmaster persona, which has ample yet softened top end and a fatter overall signal with a more thumpy bass response, remaining clear and separated with even the most outrageous fuzz pedal. If adjusted closer to the strings, the Jazzmaster pickup has no problem pushing an amp into overdrive. When it comes to the tone of JM pickups, think more twang than bite, more boom than woof, more punch than kick.

Here’s a  visual reminder to help you tell the difference between these pickups:

Offset Obfuscation

Adding to the din of confusing specifications are Fender themselves, with more varied offset models than ever. For instance, the Fender Classic Player Jazzmaster might look stock, but it actually does have P-90 pickups hidden beneath Jazzmaster covers. Same goes for the Squier J. Mascis Jazzmaster, a fantastic guitar in its own right. Oh! I almost forgot to mention another offender, the Fender Pawn Shop Bass VI, which looks as though it has a Jazzmaster pickup in the bridge position but it’s actually a humbucker!

As for obvious pickup changes, the Blacktop line of Jazzmasters has a Jazzmaster pickup in the neck paired with a humbucker in the bridge position. Then there’s the Kurt Cobain Jaguar, the Modern Player HH and the Jaguar HH with – you guessed it – dual humbuckers. Additionally, Fender’s Lee Ranaldo signature model comes equipped with re-voiced Wide Range humbuckers. Did I forget anything?


Oh yeah.

Builders other than Fender are also muddying up the definitions, some offering classic designs with fully-custom options and different pickup layouts that bring more familiar sounds to the offset table. For instance, Fano’s JM-6 model has a stoptail and a TOM style bridge with P90 pickups, much like what you’d expect from a Les Paul. Now, that’s a GREAT guitar, let there be no mistake. I bring this particular guitar up because it’s been handed to me with the attached claim that it’s ‘just like the real thing!’ which isn’t Fano’s intention at all! Man, they make nice stuff…

And, while we highly recommend Japanese-made Fender Jazzmasters as a more cost-effective alternative to their AVRI counterparts, we always recommend swapping out the pickups. Why? Because they’re essentially Strat pickups in an oversized bobbin – just a thin, tall coil the same height as a Strat pickup masquerading as something much, much cooler. These don’t even SOUND like Jazzmaster pickups, and they usually feedback like crazy! Bum deal.

The Creamery shows us the difference!

Sound Decisions

By now it’s become clear to you that there are plenty of “stock” variations between the various models offered from the factory. Luckily, we live in a time where there are more choices than ever when it comes to aftermarket pickups, and more than just brand name. For instance, Jason Lollar offers some of my favorite pickups for the Jazzmaster, and almost every guitar I own has his lovely upgrades installed. Did you know he also has a model of P-90 that’s housed in a Jazzmaster bobbin? It’s loud, authoritative like a good P-90, and has plenty of bite and growl, just like you’d expect from a Les Paul or SG Jr.

Then there’s offset hero Curtis Novak, a man that’s my first stop when I’m on the hunt for something that’s way off the beaten path while retaining a more stock appearance. Sure, he does the tried-and-true Jazzmaster pickup (also a great pickup), but he also creates stranger hybrids that absolutely beg to be played, like the JM-180.

Say you love that hallowed P.A.F. tone? Using dark magick, Novak has stuffed one into that familiar cover, and the result sounds exactly the way you want a vintage Gibson pickup to sound, and the only way you’d know it is that the pole pieces are shifted toward the neck. Maybe you love P-90s, maybe you’re a big fan of Telecaster bridge pickup? Guess what, he does that too! Or, perhaps you’ve been bitten by the DeArmond/Rowe Industries Gold Foil bug, in which case the only prescription is Novak’s Gold Foil-in-JM-housing design. It not only sounds like the best, loudest Gold Foil ever made, but having the gold color poking out of the holes in the pickup cover is like the best little secret you just can’t wait to tell.

If you’re like Other Mike and myself, you have a huge soft spot in your heart for the look and sound of vintage Mosrite guitars, especially the Ventures model. From the way they hang on a strap to that full-yet-springy sound they have when plugged in, to play one is to know the pinnacle of surf-rock coolness. Well, Novak does that, too!

Still confused? If you’ve read this far and are still wondering what the hell a Jazzmaster’s supposed to sound like, check out some sound clips of Lollar, Novak and Seymour Duncan’s amazing Antiquity I and II pickups, as well as those of actual vintage guitars.

For more great options, here are some other manufacturers you should look into: The Creamery, Lindy Fralin, Porter Pickups, and Mojotone.

Jaguar: a Kitteh of a Whole Different Breed

A rather quick note about Jaguar pickups: they’re far less confusing. Jaguar pickups are a lot like Stratocaster pickups in terms of construction and sound. The main difference is that Jaguar pickups utilize a notched metal surround known as the ‘claw’, which helps eliminate some of the hum associated with single coil pickups. Jaguar pickups are mounted directly to the body, whereas Strat pickups screw to the pickguard.

Jaguars can be much brighter overall than Jazzmasters, which is due in part to the reduced scale length; the Jaguar’s 24” makes for a springier, more twangy sound than the 25.5” standard scale. As aftermarket pickups go, there aren’t as many options for Jaguar users, with most manufacturers making a standard unit and not much else. Novak is one of the few exceptions, offering top-notch Jag replacements, Danelectro-style Lipsticks that drop right in, and even a top-mount version of a Jazzmaster pickup for those looking for a bit more oomph for their chromed-out shortscale.

“Is that a single coil in your pocket, or are you just happy to see me?”

Honestly, I wasn’t sure it was even worth getting into all of this; people have been calling JM pickups ‘soapbars’ for ages, and although it’s not really so it may be part of the guitar players’ lexicon, so who am I to try to change it! Still, I believe precise language is important especially when discussing guitar electronics and sounds, and if we’re all on the same page communication will be much easier and we’ll all get a lot more done!

Demystifying the Fender Jazzmaster and Jaguar Pt. 1

IMG_3071-impBy Michael James Adams

It’s no secret that we here at Mike & Mike’s Guitar Bar are BIG fans of Fender’s oft-maligned Jazzmaster and Jaguar guitars. Top of the line in their day, these guitars are perhaps the most misunderstood instruments that Leo Fender ever created, a sad truth that to this day follows these wonderful guitars like a scarlet letter.

Why are these guitars so misjudged? For starters, Fender’s line of “Offset” guitars – so called because of the adjusted waistline body design – shared little in common with their more straightforward brethren, the Telecaster and Stratocaster. Those guitars were plain-as-day in terms of fit and functionality; when one looks at a Tele or a Strat, there’s little question as to the purpose of their respective three- and five-way switches, where the strings anchor, or what kind of music one can play on them.

When first released in 1958, the Jazzmaster was a bit more nebulous than its forebears, intended for Jazz players who largely dismissed the guitar. The first Fender guitar with a rosewood fretboard, the Jazzmaster also included Leo’s latest innovations including the floating bridge/vibrato unit and wide, flat pickups designed to pick up more of the string’s vibrational length, resulting in less sustain and a warmer overall tone than the Telecaster or Stratocaster. Luckily, instrumental rock and surf players (and even a few country players!) soon embraced the guitar, giving the Jazzmaster a new direction.

IMG_3779-impBy the time the Jaguar was released in 1962, the surf craze was in full swing and it would appear that Leo tailor-made the guitar to appeal to instrumental rockers. Chrome for days, a slightly modified, faster body, a shorter 24″ scale and a newly-designed Fender Mute all contributed to the wild looks and distinctively percussive sound of the model.

Hard to pin down as they may have been, these two models were wildly popular in the early to mid sixties, with sales numbers overtaking those of the Strat and Tele, which were at that time experiencing stagnated sales and a general view in the guitar world as being old-fashioned. The new, sleeker Offset Fender guitars certainly sold well, but soon enough public opinion began to sour. What went wrong?

As I mentioned before, these guitars shared little of the design elements of their predecessors, which is something many of us appreciate today. Unique controls and string length behind the bridge appeal to those of us looking for something different, from shoegazers to alt. country troubadours. With that recent spate of popularity have come numerous upgraded parts that promise to improve the feel and playability of Offset guitars, including the mind-blowing Mastery Bridge and the Staytrem. Sadly, this lack of familiarity may have proved to be these models’ undoing in the long run, with players frequently complaining that the guitars were confusing, poorly made or impossible to keep in tune.

In this series, I’ll attempt to address a few of these complaints, and explain why the very designs that confound so many are, in reality, brilliant.

It’s not uncommon to hear the above phrase uttered ad nauseum at guitar stores and internet forums alike. It’s frequently followed by, “What the hell do they do?!” and “My brain hurts.” In reality, the switches aren’t all that hard to figure out, and with just a few minutes of patient open-mindedness most players can easily adapt to the layout.

IMG_3699Jazzmasters have the decidedly more familiar control layout, with a Gibsonesque three-way toggle switch on the treble-side bout. Obviously, this one changes the active pickup selection from Bridge, to Bridge and Neck, and Neck alone. The thing that tends to get murky for folks is the switch located on the upper bass-side bout: the Rhythm Circuit.

The Rhythm Circuit was designed with the intention of giving the player a darker preset sound for rhythm play. A different array of pots (50K tone, 1M volume) lends to the darker sound, contrasting nicely with the Lead Circuit’s brighter personality. (1m for both) Roller knobs poke through slots on the guard that allow the player to easily change settings without much chance of settings being changed by vigorous play. Flip that switch to its ‘up’ position and you’ve got a rounder, bassier tone at the ready, one which I frequently utilize for a clean, somber tone or to mimic synth craziness with a big fuzz and an octave pedal. Even so, most players will choose to ignore this optional circuit as a nuisance or a design flaw, but do yourself a favor and play around with it! It’s great!


L-R: ‘Strangle’ switch, Bridge Pickup, Neck Pickup. Simple.

The Jaguar, however, seems to be the guitar with the most problematic layout for some players, and while I can understand why it’s so intimidating, again I implore those stymied masses to have patience. Don’t let those little chrome plates get the best of you!

Thankfully for most, the upper bout switching is exactly the same as the Jazzmaster Rhythm Circuit. The three switches on the treble-side bout of the guitar control on/off for both pickups and what’s known as a “strangle switch”, a capacitor that can be engaged to bleed away bass frequencies, resulting in a thinned-out tone that’s perfect for biting leads or cutting rhythm work. Thanks to this, the Jaguar can easily be the most versatile guitar in a player’s arsenal.

If you’re still feeling vexed, check out the Interactive Jaguar instruction manual over at The Higher Evolution of Offset-Waist Guitars.

We’ll continue shedding light on these amazing guitars in part 2, where we discuss the floating Bridge, from its intended design to tips on keeping it functioning properly even with heavy trem use. Stay tuned!

We also believe that we perform the best Offset setups in the Pacific Northwest. If your Jazzmaster, Jaguar, Electric XII, Mustang or Bass VI needs some help to sound and play its best, stop by Mike & Mike’s Guitar Bar for a free consultation!
