Hey Guy's I got a question for Ya'll ,I recently discovered My old boss dm-2 analog delay in My parents' garage,I thought I had lost it in the 80's ,I was overjoyed to find it but after plugging it in I had the horrible recollection that at some point in the 80's I heard You could increase the delay time by messing with the adjustment screw thingy(forgive Me it was a Gilmore inspired mistake) so now it has some strange warbley stuff happening on the repeats ,I took it apart and there are TWO trim pot? screws. I really don't want to mess it up further so to make a short story long....does anyone no where to find info on putting it back to O.G. specs? is there a notch on the pot or anything basic or am I gonna have to send it to an expert.Any info would be greatly appreciated .

I have the DM-3 one says bias which I believe is the volume and the other should be clock. I would check over at the Boss area forum there are lot people who could help with this problem.

I did this with mine some time ago, one white trimpot tweaks the length of the delay, the other the bias, bring the "delay length" pot maybe 3/4 from the furthest setting and then tweak the "Bias" pot until the noise goes away, this can be done by ear while plugged in. I pushed mine to around 450ms from the standard 300ms delay time

The best advice for this pedal is NOT to mess with the trims. Good luck though getting her back to original specs.
