I got this in on consignment from a notorious pro player. It's a Fender 59 Bassman (that's the model, not the year) with some nice hot rod touches. My consigner was going for that Setzer sound.
Mods: Circuit board removed and the entire amp was rewired to pro specs (see pix). This guy doesn't mess around!
Also, 4 10" ALNICO speakers.
Tweed case has seen some road miles, but the box is sturdy and the amp sounds frigging GREAT.
He used this amp with his White Falcon, running the Atomic Brain overdrive and Line 6 delay, andI can tell you personally this sounds sweet. He's selling it because he constantly moves on in search for his perfect tone. His bandmates think he's crazy. I think his price is too low - it's the same as non-rodded amps. Here's the link and some pix...
$899 plus shipping.
