The Kingston Re-Vibe is based upon the Blackface Princeton Reverb with some mods:
RAW control to dial in the Mids. Keep it at zero and it is the basic Blackface tonestack. Turn it all the way up and now you are into some tweedy territory as the tone stack is basically bypassed.
GRIT switch added to lift the NFB to bring the dirt on a little sooner than normal.
Tremolo Pulse LED that blinks to the pulse / speed of the tremolo.
DR Spec'd Output Transformer.
All this tube goodness coming to your ears via a Mojotone BV-30V. Sounds so good with this circuit!
The cabinet is a used Mojotone cabinet that housed an earlier build that I sold the chassis out of. The cabinet shows a little wear and also has extra holes drilled into the top of the cab that accommodated a Champ sized chassis. Bolts are now in these holes to fill them in. You can see these in the picture of the top of the cabinet.
