it really shouldn't matter. it won't blow up unless you crank it.

Don't turn it above three or four because you'll blow the speaker.

They're designed to handle different frequencies: you play bass through a guitar amp, you'll **** it up. I've heard it's cool to play guitar through a bass amp though because they're made to handle a much wider range of frequencies
