[sdiy] PLL examples

[Alwyn Lloyd]

Well,
Funnily enough, i have one of those that i bought as a kit..
it worked and made some awesome noises, though it didn't seem to track
accuratly on a guitar... though i didn't have a compressor in front, which
would have probably improved it quite a bit..   still quite fun to play
with though :)


Cheers,
Alwyn
