“ Only works with HH amps (they produced this series of pedals).
Output is a 7 pin DIN, same type of connection into the front (I think) of the HH amp as the pedal is powered by the AMP....“
“It is possible, but a little involved. Said to be 18v. The only other pedal in the "series" is the Reverb, which is just the passive reverb on off switch for the HH amplifier. ... You basically identify the wires and then make a breakout cable from the multi-pin DIN.”
“The pedals get pretty hot because they use actual bulbs rather than LEDs.“
