Barber Electronics forum.

The manual states that the Half-Gainer can be run at 18v.

Safe to assume that I can run it at 12.3v using my Voodoo Lab PP2, yes? Please forgive my complete lack of knowledge regarding electronics, just want to make sure before I experiment.

Yeah, I run my Barbers (overdrives only, not the Tone Press) off the ACA 12.3 Volt setting, available on outputs #1-4 of the PP2+. Sounds good there.

Thanks! I figured that since it can handle 18v, using 12.3v wouldn't be a problem, but didn't want to take any chances. Gonna try it now!
