1957 Fender Bassman 5F6 Tweed Vintage Tube Amp 4x10 w/ Jensen P10R & Cover, Serviced


+ shipping

Up for sale, a 1957 Fender Bassman featuring the 5F6 circuit, vintage P10R Jensen speakers, and a host of vintage, USA-made tubes. Professionally retweeded by Gregg Hopkins of Vintage-Amp Restoration and an expertly serviced example, this Bassman boasts 45 all tube watts driven by a pair of USA small bottle 5881 (6L6GC) power tubes. This is also one of the very first 5F6 Bassmans produced, with a very low BM00079 serial.

While the circuit was originally engineered for bass as the name would suggest, guitar players quickly gravitated to it for its muscle, headroom, and rich overdriven grit. It's a pure, straightforward circuit, with individual Volume knobs for the two channels and a global Treble/Middle/Bass three band EQ, as well as a Presence knob. Bridging the two channels with a small 1/4" jumper allows for interactivity between the two Volume knobs for even thicker roar and sizzle.

The circuit is very original, serviced as needed to retain functionality and with strict adherence to the desired tonal properties of the 5F6 circuit. All of the original Triad transformers are intact, along with a majority of the original pots. The preamp has been fitted with a number of vintage Astron capacitors, with the electrolytic caps replaced with modern Spragues to ensure optimal performance. The power supply caps were replaced with Sprague Atoms, and a modern three-prong power cable has been installed.

The original tube chart is fully intact inside the cabinet, noting the 5F6 circuit and complete with a GH stamp that translates to August of 1957. Three of the original Jensen P10R speakers are intact, dating between the 26th and 29th weeks of 1957. One P10R dates earlier than the rest with a stamp from 1954. The blue and silver Jensen foil labels are intact on the magnet bells (the upper two speakers on a Tweed-era Bassman did not have bell covers to accommodate the chassis and transformer size).

The amp has been professionally retweeded by Gregg Hopkins of Vintage-Amp Restoration, one of the most revered sources for vintage-correct tweed work, and the oxblood grillcloth with gold stripe is also modern. The chrome chassis is in remarkably good shape, with bright plating and clean silkscreen lettering. All of the original black chicken head knobs are also intact. The leather handle is a modern replacement, and the small metal Bassman logo on the amp's face is original.

A replica Victoria Luggage-style slip cover is included.
