Doppler on Dumble/ Henry Kaiser's Dumble. Which circuit?

Post by LeftyStrat »

I'm sure most of have seen the youtube videos with Doug Doppler on Henry Kaiser's Dumble:

Anyway, any idea which circuit this is? Early 70's or a later schematic?
It's never too late to have a happy childhood.

I think the consensus was that it is an unmodified classic circuit due to the switch implementation.

The amp in the Doug Doppler videos is a 4th generation low plate classic built somewhere between 1980 - 1988...R/J has center off boost like 124..
