Hi,

I just built a BYOC Silver Pony that I purchased from Alchemy Audio. The pedal works and sounds like it should, with one exception: whenever I play I hear a distorted, fizzy sounds "underneath" the notes I'm playing. I have no idea where this is coming from. I double checked each resistor twice with my multimeter before installing them, all of my polarized caps are in the correct orientation, I'm sure the gain pot isn't shorting against the board; I don't know what's causing this. I even cleaned all of the pots with deoxit D5 and re-soldered any pads that looked questionable, but I'm still getting this annoying fizz. Could anyone who knows more about electronics and pedals help me out?

I've built three pedals from kits before, modified my tube amp, and have modded a couple DS-1 pedals in the past, so I'm not totally new at this, but I'm stumped! Thanks in advance!

Hey, sounds like you've taken the most obvious troubleshooting steps already, which is good.

To help you out, the smart folks here will need to see photos of your build. Please make them large and well-lit enough to make out the component values, and include both sides of the circuit board and all switch and jack wiring.

Turn your iron up a bit higher and reflow your joints. Also, try to clip the leads as close to the PCB as possible. There are some worrying joints there. Do this and let us know what happens.

Here's some additional guidance on that process: http://www.byocelectronics.com/board/vi ... =9&t=52188

Thanks for the suggestions! I read your instructions and reflowed every single solder joint and double checked everything to ensure there are no shorts. I reseated the ICs in the slots to ensure there was a good connection, too. The buffer sounds great but still, when I play with the effect on, I'm getting the same fizzy artifact "underneath" when I play notes through the pedal. Do you guys have any other ideas? I appreciate all of your help!
