I want to disconnect one speaker in my Rebel 30 2x12. Does the Ohm setting need to be changed????
 
Most likely your speakers are wired in paralel, and that means that disconecting one of them doubles the impedance.
 
or, if they're in series, halves it.

curiously, why are you disconnecting one speaker?
 
You should be able to see the ohm rating on each speaker. If you only run one, then set the amp to what is says on the speaker. I'm assuming it's two 16 ohm speakers in parallel for an 8 ohm total. If you run one, just switch it to 16 ohm.
 
Thanks - just looking for a little less volume, a little more speaker distortion and I am going try various speakers to find the tone I like.
 
Always remember the impedance on an amp is a minimum impedance. This means you need more load than your amp is set to. So:

Amp set to 4 ohms with 4-ohm load = OK
Amp set to 4 ohms with 8-ohm load = OK (Will shorten tube life)
Amp set to 4 ohms with 16-ohm load = OK (Will shorten tube life)
Amp set to 8 ohms with 8-ohm load = OK
Amp set to 8 ohms with 16-ohm load = OK (Will shorten tube life)
Amp set to 16 ohms with 16-ohm load = OK

Cheers,
 
With the speakers wired in series, how do I bypass one speaker??

You can either install a jumper across the two terminals of the speaker you don't want to use, or disconnect the leads from that speaker and connect the leads together, leaving that speaker out of the circuit.
