1967 Fender Twin Reverb
We got this cabinet from Eric Johnson (still have the shipping label) Then we put this great old Blackface Twin chassis in it, with a built in foot operated (VMT) speaker controller. Hey Eric, you want it back? Ok, we put a couple holes in this one. The red switch eliminates negative feedback. And the other hole (by the power outlet) is for the foot controller. If you unplug the foot control cord, the amp reverts to normal mode.
