Hi y'all...  

I have a q on the DOD delay pedals (DFX-9, 94, etc.)  My next step 
will be to open one up and tweak away to see what they do but I was 
wondering if anyone knew offhand what the 3 trim pots inside do.  I 
assume one has to do with the fine tuning of the sample rate (and 
subsequent delay times), one has to do with the gain of the gain of 
the delay feedback signal, and one the input gain.  It would be 
helpful if someone has tweaked these before and has info to share.

(Not quite on topic, but as likely a place to ask as I could think 
of.)
