Title: Snackshack "works" but sounds awful/ has a problem [resolved]
Post by: harryklippton on December 09, 2020, 07:46:58 PM
I assembled two snack shacks back in June, one on an etched board for a friend that worked perfectly, and this one with issues on the giveaway board. I left it for several months and picked it up again recently. I'm using a 3904 in Q1 and a BC182L in Q2. I've checked the pinout in the bc182. Admittedly, the soldering isn't my best work, and I reflowed everything the other day. The pedal works correctly, but it's very buzzy. It gets worse when the circuit is engaged, and there's a loud whine that sweeps in frequency when turning the dirt pot. I really tried to get this straightened out before asking for help  :-[ any advice would be greatly appreciated

Well I got this fixed. I swapped the signal and ground connections on the in AND out jacks  :o

Can't say I haven't done that.
