Is there a lot of soldering to do on the board then? It looked pretty much finished from the side that they show. You will have to "do" the 20 second looper next http://instructibles.com/id/EFKSQRX8Z0EP287017/?comments=all (parts from Rapid in the UK total about £10 - fun and easy build)
No, there's only a tiny tiny amount of soldering (attaching battery clips and jacks) but I'm completely useless at it. Also, I didn't want to install it IN a guitar, and I wanted to modify it a bit. I finished it last night in a temporary box and it's great. Has a small red button on the front which short circuits a couple of legs on the chip for 'kick the spring reverb' type feedback effect.
"youtube mothpiece"? Please. Would you rather just read that some guy built a huge Flying V, maybe with a couple static images, or actually SEE it? MusicThing is still great; just because it's adopting technologies that are available doesn't diminish it in any way.
Perhaps you'd like to show us all the way it should be done?
