WOW WOW WOW !!!
Awesome sound. Don't think about it, if you can, you must buy yourself a Crack.
What did I learn on the build:
Crack: the LED's between A3 and A8 are very fragile (I broke one and had to find replacements) but that's about it.
Speedball: 2 things a) the 24swg i.e thin cable needs a really good wire cutter to not damage the core, b) read the resistors carefully!
Thanks for your quick and helpful responses.
