Has anyone tried to adjust the bias adjustment on a boss dm-3. I have 2 of
these pedals and one is great sounding, the other is flat and weak. I'd
like to try to adlust the bias on the pedal(there is three) Can i take the
values from the one pedal and apply to the weak one? If so, where do I hook
my meter up?

There should be 3 legs on each trim pot. you will have to take the pedal
apart then flip the board over. Your speaking about the clock speed. You
really need a oscilloscope, but if you listen closely you might hear some
clock noise in the delay. Adjust until it's not audible

The problem with the delay is that it's not as clear as my other dm-3. It
just sounds tired.

A thing to note is that just because all the parts are identical doesn't
mean every pedal will sound the same. Try the clock speed thing brian
suggested and see if that helps.
