Two heads into one cab

[tbm]

Me and another lad go between guitar and bass a lot in our band. With the bass its fine, but we can't really get on with each others guitar tones so we want to run the two heads into a single 2x12 cab. Aside from hitting standby and physically switching the cable, is there a cheapish and safe way of doing this with an a/b switch? We really don't want to fork out for a Radial Headbone?

If you're not switching on the fly, the best and safest way is to put the amps on standby and move the cable. With an A/B switch, even with the amps on standby for the actual switching, you're still introducing more potential unreliability into the chain with multiple connections and switch contacts in the circuit, which is always a bad thing.

The Headbone is really the only way to do this, if you want to use an AB switch you will need to get two cabs

as the others said, you have to have a special switch, or split the cab and run each amp into one of the speakers.
