[sdiy] Buzzing reverb

[jays at aracnet.com]

You haven't moved it next to something that has a lot of EMI have you?

Reverbs are great for picking up AC hum from computer monitors and other units power supplies.

Like Harry said, either bad caps or bad ground would be my guess after EMI. Usually linear power supplies aren't that bad to deal with.
