Hooking up an amp head to a combo amp.

[michael_atw]

Is there a way to do it? My guitarist friend has a Marshall JCM 900 combo amp but I wanted to let him borrow one of my Ampeg B25 heads. He has no speaker cab and I have none to loan him, so I was wondering if there was a way to hook up the head to the combo and somehow bypass the electronics on his combo?

Thanks ahead of time!

Many combo amps have connectors in the back that let you unplug the combo's speaker, and plug into a different cab. I guess you want the reverse here. Just take a look at the back and see if the Marshall has that. I have a Mesa Boogie guitar amp and it has this setup.
