Ok i just bid on this JCM 900 on ebay, the model 4100

Thats the high gain one right?

i hope so, if not...

itll be cool ill get a overdrive
If i win, would it be possible to wire it to another combo?

I have a crate with 2 speakers and i was wondering can i hook those speakers up to the JCM ( if i win lol)
its not called the "high-gain" amp but it is a high gain amp. It still sounds good though. You can hook it up to your combo if you can disengage the amplifier in the combo and the speakers can handle it.
yeah it says the speakers are eight ohm, and that amp handles eight ohm BUT! my crate amp has speakers connected directly into the amp, is there a way to ad a 1/4 jack onto it?
