I advertise for pedal repair on Craigslist and this morning a man called me from Georgia and said he has a 1970's stereo Memory Man that has a hum that builds over time.

My question isn't how to fix it(I'm sure I can figure it out), but would it be prudent to take gut shots to maybe make a clone? Or is this pedal old news? I'm not educated on the values and rarity of vintage pedals.

So lemme know what you think and if it's worth it to take some gut shots and make a copy.

I'm sorry sir, we only have the regular ohms.

A clone would require out of production delay ICs, notably the SAD1024A or MN3005, depending on which model the Memory Man is.  Unless you've got them hanging around it's probably not worth cloning.

If the pedal is running a SAD1024 or a MN3005 then you will probably be looking at 12V or maybe even 15V.

However, the problem sounds like a cap to me too!  ;D

If it's from the 70's, that's about a 35 year-old cap.  Isn't that something like 20 in dog years?
