Up for sale, a 2008 Modulus FB4 Flea Bass in exceptional, 100% original condition and in perfect working order, complete with the original hardshell case. First released in the late ‘90s, the FB4 was Modulus and Flea’s collaborative interpretation of the Music Man StingRay platform, seen for years in the hands of the Red Hot Chili Peppers bassist and heard on some of their most iconic recordings. This particular iteration was produced in 2008, in the final year of the partnership between Modulus and Flea; in 2009, the model rebranded as the Funk Unlimited.
Currently offering exceedingly limited production with only four Modulus basses made per month, the FB4 represents one of sparingly few Modulus instruments in circulation. Featuring an alder body, carbon fiber neck, and composite fretboard, this bass has a resonant acoustic platform with plenty of sonic heft, faithfully captured by the Bartolini MM humbucker. This powerful pickup has a rich, deep tone, delivering strong midrange warmth and specially designed with an enhanced treble response perfectly tailored to slaps and pops. The Aguilar OBP-1 active preamp has independent Treble and Bass EQ knobs, offering up to 18dB of boost at 40Hz for the bass and 4kHz for the treble. This Modulus weighs 9lbs 1oz, professionally setup here at Mike & Mike’s Guitar Bar with 45-100 roundwound strings, easy-playing action, and spot-on intonation.
The carbon fiber neck has a slender C-shaped profile carve with modest shoulders at the nut, offering a gentle increase on overall heft and shoulder up the fretboard, measuring .745” deep at the 1st fret and .935” at the 12th. The composite fretboard has a compound 12-16” radius, and the medium jumbo fretwire is nigh flawless. This bass plays cleanly up the 34” scale with an arrow straight neck with a responsive, optimally-adjusted truss rod; the carbon fiber construction ensures optimal stability, highly resistant to temperature fluctuations and extremely reliable. The graphite nut measures 1.56” in width. On the headstock, the black Modulus-branded tuning machines turn smoothly and hold accurate pitch.
All of the electronics function as intended; the Bartolini MM humbucker is governed by a Master Volume control and the Aguilar OBP-1 preamp with Bass and Treble EQ knobs. The OBP-1 is powered by a pair of 9V batteries. The black-plated hardware is notably clean, including the dome-top knurled knobs and the Badass Bass II heavy duty toploader bridge. The four-ply gray pearloid pickguard rounds out the plastics, with requisite scuffing along the pick path and pick wear extending beyond the treble-side corner of the humbucker.
Cosmetic wear on the gloss Black finish is limited to an area of light buckle rash on the back central to the waist and just a handful of tiny dings and faint scratches in the clear coat on the body as a whole. The silky smooth finish on the neck profile is nigh-flawless, with one small finish chip in the clear coat on the treble-side binding and some minor isolated cloudiness (also in the clear coat) primarily along the bass-side binding edge.
The original molded hardshell case is included.
