I've got a Boss OD-3,and I can't figure out what frequency is causing the "Ice pick in the forehead highs" that you can't dial out.The BD-2 is the same way.Any help on this problem would be greatly appreciated!Here's the schematic;http://www.freeinfosociety.com/electronics/schemview.php?id=2299
Just watched some demos on YT of the OD3 and it sounds pretty darn good. Definitely not hearing the icepick you're talking about... But, there is surely a cap or two you can tweak to lower the highs. Maybe if you dig up a schematic the smart people will help you out. Good luck :s
Oi... time to get that 2nd coffee. heh
Yeah,I just don't know which cap,or caps to change.The schematic is linked on my post.Any ideas?
Looks like lots of tone shaping around the 2 op amps before the tone control.
C16 - .012uf appears to be rolling off some highs. Try .022uf or .047uf to roll them off some more. ;)
