Question: Is there any risk of damaging anything if I plug 2 bass amps into 1 cabinet? The reason I'm asking is, tonight is my first gig on bass. I am a suspenders and belt kinda guy. I'm told that the place we're playing has questionable wiring. Also, I bought my SVT2 used and I do not know if it has the bypass mod to keep it from shutting down if it gets low voltage. I'm going to take a circuit tester and do my best to make sure I'm plugged into good power, but if the wiring is questionable, then I reckon even a plug that tests good could still end up exhibiting problems at some point. And the circuit tester won't alert me to low voltage anyway, I don't think. My main amp is an SVT2Pro. My backup is a Promethean. Ideally, I would like to have both amps on and plugged into my cabinet so that, if the SVT shuts down, I can just pull my instrument cable out, plug it into the Promethean and resume playing. It seems like it should be okay to have 2 amps both running one cab, as long as the combined input did not exceed the cabinet's power rating. But, it occurs to me that if both amps are plugged into the same cabinet, the juice from the SVT will be going into the cab and then also out the other speaker cable to the Promethean. So, maybe it would damage it? Does it matter if the Promethean is on or off in this scenario? Thanks for any help!
