Catalinbread Formula No5 GAin

[Pavlos]

I've got the Catalinbread Formula No5 board finished and it sounds great, however even with the gain backed right off it is still quite overdriven and I have to back the guitar volume right down for it to get even close to being clean(ish) Now as I prefer more edge of breakup - crunchy - milder overdrive, is there a way to tame the overall gain of the circuit a bit so that it starts cleaner and is a little less hairy when maxed out?

many thanks in advance

This circuit responds really well to an 18V power supply. I found that at 9V I couldn't back off my guitar volume enough to get it reasonably clean even at the lowest gain settings. At 18V, though, I can get a nice range from slight grit to facemelt with just the guitar volume and the gain set at about 8 or 9 o'clock.

Make sure your electros are rated for 24V or higher before you try it.

With something like this, could you a/b a resistor on the input with a switch to increase the impedance and give the option for either response?
