    Big Muff Pi on a breadboard - passes signal until power is applied.

    Found the ref des. Will use it from now on.

    Big Muff Pi on a breadboard - passes signal until power is applied.

    Thanks BuddytheReow. A few questions... C1 - drawn with polarity but, it doesn't matter? Why would someone do that? C3 and R6 - not on my drawing... I mean no wonder it's not working if it's missing critical components or is mis-drawing others! What is a "ref des" (I assume reference...

    Also Thanks gtfields for spotting that mistake.

    Big Muff Pi on a breadboard - passes signal until power is applied.

    I think emitter left, flat side facing is what I'm already doing? Anyway, I have just rebuilt the circuit on a better breadboard and, unsurprisingly, am getting better results. You sir have probably saved me much pain. Many thanks for that. Would appreciate any one taking a look at the new...

    Big Muff Pi on a breadboard - passes signal until power is applied.

    2n5088's from Mouser. I checked the datasheet for the pinouts. Wasn't completely clear to me which was which...they listed emitter as 1, base 2 and collector 3 followed but there's no image with the numbers pointing to the pins. The main image had it oriented flat side ot so I just assumed it...

    Oh ignore my diode question. Just rechecked the circuit....

    Big Muff Pi on a breadboard - passes signal until power is applied.

    Thanks Feral Feline. More great advice and tips. I've built and rebuilt probably 20 times trying to simplify it. Good to know I need to do it again. One reason for the jumpers was to try to physically distance components which helps me trace it. But yeah I probably have too many. Love your...

    Big Muff Pi on a breadboard - passes signal until power is applied.

    Hi neiltheseal. Thanks for the reply. Probably an obvious question but what sounds should I hear after each stage? I did that after the input booster. Just got the same low volume clean tone, and the pot didn't seem to behave like I thought it would increasing volume when turning clockwise. I...

    Big Muff Pi on a breadboard - passes signal until power is applied.

    Hiyas, Total noob looking for some help. Not sure if I deserve any.... With no power connected, I get a clean signal passing through. When I plug the 9v (wall wart PSU) in, I get 1-2 seconds of total silence then a constant tick-tick-tick sound, maybe 10-12 ticks per second. Same results...
