First time posting,
I am dealing with an attenuator problem with my 1982 JCM 800 4010 combo.
Normally it sounds awesome no problems. I recently acquired a really nice attenuator (not mentioning brand).
This attenuator has a built in effects loop that was was part of the decision to purchase it in the first place.
Hooked everything up correctly and was experimenting with different ways of adding effects. I realized that unless I ran the effects only through the front of the amp was the only way to avoid mild shocks when touching the pedals or the speaker cable plugs.
I've already made sure there were no problems with the outlet I was plugged into and made sure everything was on the same power strip. I tried using separate outlets as well.
I first noticed the problems when I used the effects loop. Essentially using the effects loop is a no-go. As well this thing has a headphone jack. I can't imagine the safety hazard there.
Is it a well known problem that you can't combine an attenuator with effects in the loop on a JCM 800? I'm sick of experimenting after being mildly shocked several times. Do I need a power conditioner? Is there something I can add to the effects chain that will eliminate ground loops?
Please help.
