I’m not really sure what it controls. He says that in his mind it pans from a Bluebreaker sound to a more ODS sound. I didn’t play it enough to actually come up with that conclusion. What is your take on it?

I wish I would have read this before building this pedal.  I’ve had a v1 board sitting around for quite some time. I completed it last night and had the same gain pot problem. of course, I didn’t realize I had that problem until I plugged it in. I love reading these old threads and seeing what you guys come up with in your trou…Read more

Although it works, it is hot! After biasing, this boost is too loud!

Should I treat the MPF 102 as a J201 and put a jumper in R1? Or should I remove and install the J113? At the time of populating the board, I didn’t have a J113. I have some now.  Thanks!

I’m not sure why I didn’t get pics of the Apollo and the Black Dog painted and complete. Guess I forgot. I should get those back in a couple of days. Unless the guy wants to buy them. I let him try them out first.

A buddy of mine wants a Klon and Prince of Tone in 1 box. What is the usual choice enclosure for dual builds?
