Does anyone know if there is any reason the airbrake won't work with my 60 watt Fender Prosonic? The tone on this thing is great but my ears blead past 1. Someone had an idea that an attenuator wouldn't work because my amp has a master volume.......The master volume isn't really a master volume however. The master only works in the drive channel not the clean channel. Should still work right? I'm confused I also have a Mesa that has both a volume and a "Master Output" which works like a built in attenuator or what I would consider a master volume. Prosonic doesn't. Help.
