This 1964 Fender Bassman came to me sounding good. But I knew eventually I’d want a pro to look at it. If for no other reason than to confirm it’s circuit and age. I suspected it was rare.
The amp is indeed from December 1964 and a AA864 circuit. But someone replaced most of the capacitors, resistors, etc and they did a realy bad soldering job. Fortunately Tim at Superfine Ampworks set things right!
Now the normal channel sounds like an amazing Fender clean with all the power and responsiveness you’d want. With a original specs closed back cab and two Webber speakers running at 4 ohms it’s loud and clear. And the bass channel has been modified to the Superfine-tweaked version of the Marshall JMP / JCM800 Master Volume preamp circuit as found on the late 70′ and early 80’s Marshall 2203 / 2204 amps.
Now I have THE ultimate super sleeper! A dream amp and my absolute favorite.
I have just begun to scratch the surface of what it can do. Immediately I dialed in sounds that had me writing and jamming! Just what you want from a magical musical tool. Now to try some effects with it. (Reverb tank, fuzz, boost, etc.) Though I could spend lifetimes without them and be in nirvana. Thanks Tim!
