Hey, belated thanks Sebastien et. al.!

Here's a sample of what the noise on the main outs and headphone outs sounds like:

As you can hear, it's sort of a general crackly cloudiness. I reckon it's more than just a dusty or faulty slider, as it wasn't dispelled or diminished in the slightest by a squirt of contact cleaner, and the noise gets smoothly louder and quieter as I adjust the main volume slider. Nevertheless, I guess you've given me a hint about where to look.

In this clip you'll also hear that the Hand Clap & Tambourine are excessively loud. Also, their slider doesn't seem to do anything.

Here's where the mod wires run to:

As you can see they run to various places labeled D3XX on the switch board. Anybody know which mod this might be

Again, thanks to all those who replied to my first post.
