Here's my Creeper from back 10 years ago when my son was really into Minecraft. Sadly, the most I can say for offboard wiring skills improvement is that I use zip ties now! I didn't realize the diode switch was on/off/on (and is probably wired wrong) so somehow the middle position is super loud and overdriven. It sounds good though so I left it as-is.

It's a Son of Clay Jones Overdrive, which is a tweaked Son of Screamer. Definitely in the Tube Screamer ballpark, but 100% more Minecraft. Also, decals on the sides really is a PITA.
