I've been trying to figure out why when I use the effects loop I get so much noise. It seems to be coming from the send jack, as soon as I plug a cord into the send the VM becomes noisy. It's not as noticable on LDR. I have to use a noise suppressor to get the noise under control, which kind of sucks. I'm only using a delay and noise suppressor in the loop. I replaced all the preamp and power tubes recently but that didn't fix it. SteveD or anyone have any ideas what's going here?
If I don't use the effects loop at the all the amp is pretty darn quiet in LDR and HDR.
