Well I feel foolish. I have owned dozens of overdrives (not as many as some around here...), many of them costing well over $200 and I just recently picked up a Boss SD-1 that does amazing things for $30. With my setup and what I am going for, I can't imagine anything doing it better. I modded it ever so slightly by changing C3 to 0.1uF for more bass response and changing C6 to .005uF to open up the top end a bit. I don't remember being this wowed by an overdrive in quite some time. I know it is still the honeymoon, but its a very good honeymoon. The bypass isn't great and there is a bit of an effect bleedthrough on bypass, but I already keep my overdrives in a loop so that is a non issue for me. The longer I play and better I get at guitar, the more Boss ends up on my board... What gives?
