    I worked with a guitarist who played an Esquire and a brown face Concert Amp. He painted this beautiful screaming amp black. He had a great sound with that old Esquire rear pick up and the non-reverb 4×10″ Concert. This was in 1972 so I didn’t know anything about the value of his guitar & amp. Pure Fender! tHOSE WERE THE DAYS. Skip “Alex” Spence, our lead player played through an amp custom built for him. The tech for Moby Grape put together (4) Twin Reverb amps into one monster amp. This pushed (4) 4×12″ custom built  speaker bottoms.

      Yea, the Concert paired with that Esquire is the same set up that we hear on the first Steppenwolf album. Yea, the entire album I understand was recorded with this set up. Born to be Wild, Jupiter’s child, The Pusher, yep! Great tone I would say…and a winning hand…..Its the tone I chased for years. Finely got this set up, and bingo!

    I was digging through my grand fathers attic and came across this amp staring back at me.  He bought it new back in 1960, played for a month or so and locked it away.  It is is PERFECT condition.  Along with the amp he bought a Buddy Holly edition fender strat, which a frind so lovingly took off him for a few hundred bucks (FML).  Anyway I took the amp home and in the process of having the speakers re-conned.  I am super excited to hear how this baby sounds!

    Just picked up a Concert (6G12-A) last night for $600. It’s pretty beat up and the output transformer has been replaced with what looks like maybe a Super OT. Still sounds phenomenal. Needs some work, though. I’ll crack it open this weekend, but I’m almost sure it needs to be recapped. I’ll probably need to recone the speakers at some point as well. Incredible deal, though. It just sounds like gold, even in rough shape. No telling how amazing it’ll sound after being tuned up.

    Pdyckman, I played with Skip in ’72 as well, right after I moved to California, and I remember that amp. The “tech for Moby Grape” you mention was Howard Dumble, now known as Alexander Dumble. IIRC those amp[s were actually 4 4×10 Bassman circuits in one chassis, with some of the famous Dumble magic applied. Shortly after that the amp was stolen and as far as I know never recovered. I’ve always wondered what happened to it.
