Seeing as i'm soon to be dealing with a 100W head with no master volume at home, i was looking at some attenuators - and seeing as i'm a cheap ass student, they're all way out of budget. I keep seeing effects loop attenuators - my guess is these are just volume pedals with a low impedance input/output. Am i getting it right or did i miss something? If that's the case, it might be worth to just get a simple EQ pedal, or cut the effects loop level, as all it's ever going to do is drive the PI tube. Any insight?
