Gonna compete with Super Bowl?
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Oops! Just read the post this morning. I missed that it was on Saturday.

I've uploaded Video 8 in the dumble Build series.  It covers the footswitch build process, as I was too busy with my day job to do much this week. 



I'm also going to do another Saturday Livestream, so come check it out, 11am PST, 2pm EST. Click here to get to that stream:
