I made a very gnarly overdrive by basically sticking together two overdrive circuits one after the other.
It sounds great but is roasting the amp because the output is so loud.
Is there an easy way to lower the output without compromising the tone? Or do I need to get into the nitty gritties of the entire circuit as a whole entity?
Could you plz post a schematic,,?? :icon_wink:

Thanks for the quick response. I don't really have one of the whole circuit, it's just breadboard, but it's essentially just two ehx muff fuzzes Stück together as in the attached schematic for just one.

Hello.
Have you seen the PAIA Quadrafuzz??
Maybe you just need a mixer to mix the 2 fuzzes??
Hey Aron, the "quick edit" thingie WORKS!!!
Am I missing something? There is a volume pot at the end of that circuit that will turn the output level down to nothing. Even with two in a row, with the volume pot turned all the way down there should be no sound.
Is the issue that the pot is too sensitive as you turn it down? Hard to go from just a little too loud to completely off? If so, try replacing the volume pot with a smaller value and a series resistor between the pot and C3, so the total resistance is still pretty close to 100k. Say a 50k pot and a 47k resistor or a 10k pot and a 91k or 100k resistor. It will be like having a 100k pot with all the adjustability between, respectably, 0 ohms and 50k ohms or 0 ohms and 10k ohms.

Despite the number of cascaded circuits, output amplitude can't be higher than 200mV
RMS (about 550mV
p-p)..
(for D1/D2 Ge diodes..)
What's your amp input sensitivity..??
Welcome....are you really 'roasting the amp', or are you feeding an already clipped signal from the first boost into the 2nd, resulting in that massive fart sound of too much distortion? That can really sound like poo.
Solution would be to lower the output and drive of the 1st one to taste.

If you already have an output volume pot it sounds like you may be using a linear taper pot, which is hard to adjust. Find a logarithmic pot.
