was just wondering if i could safely use a AB switch with a Peavey Classic 50 212 combo? the two channels require a switch where i can plug in a 1/4 cable for each channel. i can do that with my AB switch, but there is an option on the switch that enables the use of combining A and B at the same time along with A or B.

that would mean i was using both preamps on the amp at once? will that F it up?

here is a link to what the top looks like on the amp
Sometimes i walk outside and stare at the Sun and sigh at its massive beauty, a Glowing Beacon of Light. Then i begin to see spots...My Eyes Burn, Retinas begin to become Torched!....Sometimes i Hate the Sun...
