While connecting my VF-1 into the effects loop of my Read last night (heresy, I know, but I wanted to try it out), I noticed that the send/return jacks on the back of the Read were TRS jacks. Does anyone know if these are balanced? I assumed they are unbalanced like typical loops, but TRS phone jacks were definately used. Anyone know why? Also, would there be a copy of the Read owners manual online anywhere? Maybe that would explain this... Thanks!
