Finished the soldering two days ago, added the built in speaker to the mono-out breaker so when it's plugged to a speaker cabinet, the internal speaker turns off.
I was looking for something to build it into but couldn't find any plastic or metal boxes that would fit the small speaker I had. But then I found a magic 8 ball that had too little fluid left in it to work and the hole looked big enough for the speaker to work without modification.
How to disassemble a magic 8 ball:
* Hammer to the little window, pour out the fluid, rinse and repeat.
* Break stuff up inside with needle nose pliers, knives, hammers and such. Then and pull out shrapnel.
* Crack the glue on the screw thread.
Turned out great! Gonna post some pictures tomorrow if I can get my camera working.
