Hi all,
Currently building the Triangulum Boost (clone of a Fortin 33). Surprise surprise, it doesn't work.
The LED works, I get sound with the pedal on bypass but with MASSIVE earth/ground hum. When the pedal is engaged I get a different hum (60hz?). I'm taking this to be two seperate problems.
When the pot is turned, the hum sounds different. Well, to be honest it sounds like an interference hum with a clean boost dimed
This makes me think the pedal is functioning correctly, but the issue is with the signal getting through the switch.
I've checked continuity through the pins of the footswitch, all seems fine.
I've used IPA and scrubbed the back of the board with a toothbrush.
I've re-flowed the solder joints, including adding more solder to any suspect looking ones.
I've noticed that IC1 doesn't get warm, only IC100. I checked the voltages and whilst I can't remember them exactly, they didn't seem to match up to what they should be.
I'm a bit stuck for ideas now.
Pics attached below. The zoomed in pic is to show those rogue strands of wire aren't making contact.
If you're explaining things, please speak like you're talking to your dog. This is probably only the 10th time I've soldered anything. I don't have a great understanding of electronics, but at least I'm honest! I wanted to build the pedals I couldn't afford/find locally, rather than start a pedal building business or something.
First build & first post, be gentle please! Thanks for reading!
