Fender Twin w/ Fulltone fulldrive 2 Mosfet

[teepeeasel]

I am currently loving the Fulltone pedal on my Twin, it adds the OD that i've been seeking for sometime now, reason being, it doesn't color the clean tone of the amp. My only complaint is that id like to have more OD from the pedal and ive got it pushed to the max, any suggestions on boosting the OD more. Also, Fulltone has 2 options for supplying power to it 9v and 18v, im using 9v now, does anyone have experience with the 18v? Would you recommend it?

[HTH]

18v would give more headroom, therefore less gain/compression (slightly).

to get more gain, locate the 4k7 resistor and 0.1uF cap coming from pin2 of the first opamp stage.

lowering the 4k7 resistor gives more gain - down to 3k3 should give you enough extra gain if you only want a little more. down to 1k would give you quite insane amounts of gain.

for simplicity, just solder another resistor in parallel with the existing 4k7. A 10k resistor will give you 3.2k which is close enough for jazz.
