There has been some discussion about the buffer being too noisy. After trying all the suggested remedies, I tried jumping R12 and that cut out most all the buffer noise. Granted this pedal didn't show signs of a noisy buffer until I tried it in front of a high gain amp, then it stood out like crazy. Now with the delay chips out of the circuit, it is no more noisy than just the guitar and cable. Hopefully this can help those who have posted about the noise. I dont know if this is a universal "fix" or if it was just my pedal, but I am much happier with it. Now if I can get the delay chips to quiet down a bit.....

Nice job Gearu, thanks for the report!

Regarding the delay chip noise, most designs just increase the wet signal filtering to cut chip noise. There is no real magic bullet I know of there. If you look at the schematic, you can play with filtering the wet signal differently at R21/C22 & R29/C24, C17, C18, C29, C30. Or check out the wet signal filter sections in the circuits with BBDs (flanger, chorus A delay) for some other ideas.
