was wondering if anyone has experience linking 2 combo amps for more volume. I have a Ampeg B100-R, and thought that if I come to the point of needing more volume, why not just get another one? I'd run out of the line out of one of them into the hi-gain (?) input of the other one. I just know that people say that 2 ways of increasing volume are to double your power (=+3dB) and increase the number of speakers, or speaker area. It seems to me I could get another 6 dB+ for about $300 if I buy right. And what a cool looking rig.... Any thoughts?
