 I know this will be a fairly easy answer, but will using a vibratone cabinet damage my OT tranny, seeing that it halves the ohms at the flick of a switch. Cheers,

 It shouldn't, escpecially if you're using a Fender amp. All Fenders (or at least all older models) have an ext. speaker jack, which once you plug in a speaker, effectively lowers the load impedance.

Plug n' play!

 But if I use it for a gig all night will it fry it. Considering your changing from 8 ohms to 4 ohms on and off without turning the amp on standby. It's basically having a SPST switch kicking in an extra speaker cabinet.

 Most Fender amps can handle up to a 100% mismatch on the OT.
