Joyo sweet baby overdrive purchased from this board. It can get a medium level of drive but its magic is as a low gain drive which doesn't colour the sound, I have used it into my tubescreamer with the TS also on lowish drive so the two on together with a compressor make a fairly high gain (nothing metally).
Lovely pedal, not original knobs but they are joyo knobs.

Would trade for a similar cheapy pedal with spring reverb, biyang etc.
