I'm considering building an amp that was designed with a tremolo circuit (Martin 112T); I've been told the tremolo sounds GREAT but that when you don't want trem, the amp performs a lot better when you just pull the tube (V6). It appears that the only connections this tube has to the other circuitry (other than the filaments) is the lead from the depth pot to the bias on V1 cathode (pin 8) and the B+ coming off the 15uF filter cap. I'm thinking of putting in a DPDT switch to disconnect both these connections. Seems like this would essentially remove the tube from the circuit. If this seems like a bad idea--I may be missing something really obvious--I'd like to hear about it.
