Title: Delta Blues OD Channel Problem
Post by: plexi50 on March 11, 2012, 01:56:14 pm

Delta Blues that has no sound when switching to the overdrive channel
I have tried the footswitch and no go either. Checked the panel button switch and it is good
Checked the resistor values in the OD circuit and they are good as well

Im missing something /

No it does not make any noise at all or buzz when those points are touched when the OD button is engaged

New relay installed and OD channel works fine again. I wont forget this one. Very easy changeout.
PRR makes life less stressful. Thankyou again!
