Hey gang, here's a video I made with a build report and demo of my MXR Distortion+ kit from GGG,
It didn't work at first and after checking the solders and values, I started swapping components and using a probe to search for the problem. Eventually discovering I had two resistors transposed (4k7 / 1M) because of a typo in the documents! Dang.
So after a long haul of debugging, and a lot of forum searches and reading, I got the pedal working great.

Nicely done, I like it. That was a very good catch. The only change I made was the distortion pot. Lowered it to about 100k. It doesn't get all the way clean, but with both the volume and the distortion pot at 3:00, it sounds fantastic.

thanks Jimilee, yes I think I say at 7:00 that I want to try changing the pot to 100kC (as recommended by Mark Hammer)

Quote from: half_smith on June 07, 2021, 03:42:58 AMOh yeah, I remember why I said that. I didn't change anything else, I just changed the pot. I wanted to try to keep it as close to the original as I could....and I didn't want to mess with changing resistors, just too much work on an etched board.

I see. I guess I had already desoldered practically every component in my debut debugging fiasco
