First pedal issue (Fuzz face)
« on: July 29, 2019, 05:44:25 PM »
Hi all, I was wondering if someone on here could help with an an issue I'm having with a fuzz face breadboard project.
I have gone by the NPN schematic on this site -
The issue I'm having is I get almost zero volume. I'm using BC108C for Q1 & Q2. The only difference I have to the schematic is I am using 2 resistors in series for the 8.2k (adding to only 8k as I couldn't find an 8.2). I'm also powering it with a 9v adaptor.

Can anyone tell me where I should first look for issues (beyond checking it's wired correctly, as I've rebuilt 5-6 times and followed the schematic exactly each time with the same results)?

Welcome, James!  You might want to ask a mod to move this to the main "Building your own stompbox" area of the forum (or just re-post) - there's far more passing traffic there.  (This section is for the forum "beginner project", and there's hardly any footfall here.)

You'll also find a very handy, sticky "Debugging" thread when you get there.  Follow the instructions and post your findings - it really works: we'll definitely get you sorted!  :)

If all else stands correct, I would try taking the output from the Collector of Q2 instead of on top of the 8k Resistor were it meets the power supply.

Try to post a picture, fortunately I have a Si fuzz face in the breadboard too, let´s see what you´ve got.
