Before I was directed to this forum I wanted to build a treble booster for my pedalboard. I found a schematic and PCB layout on fuzzcentral and used the laser printer toner transfer method to make the board at home.

I'm liking the sound a lot. :)
The inside is a mess because I didn't consider the size of the jacks when picking the 1590a but I got it all stuffed inside (rather sloppily) and this was the first time I touched a soldering iron in probably 28 years so that's not so nice either.
Next one will be better though.
