I know that's probably not very smart, but just as a *very temporary* solution, is it possible to saftley do this (without getting shocked or something...)?

Obviously, I'd start at the lowest volumes and move up... And as long as it won't kill me, I'd like to try it out until I can get a cab...

hope this helps

23. Never, ever, plug the speaker output of one amp into the guitar or line level input of another amp. There is a way to do this without harm, but you need a special interface. This can be a very expensive mistake if not avoided. If your amp has a line output jack, this is a safe signal level to plug into another amplifier's line input. The line output of some amps is fairly large (a volt or more) and may distort the guitar level input of your amplifier. Try using the second input jack on your input channel which is typically 6 db less sensitive, and therefore, less likely to distort the preamplifier stages when a large input signal is presented.

Can I plug the output of one amplifier into the input of another to make it louder?
You can, but you will likely blow it up. Don't even think about it.

What's wrong with using the amp by itself?

If it's not loud enough when it's maxed out, then another head won't help.

I know, it was just for a temporary placement thing. I was looking at purchasing a head, but I don't have a cab, so I thought, until I can get a cab, maybe that would work temporarily (if only to be able to test the functionality of said head).

If you're just looking for a temporary cab, my old guitar player had a workaround when he was in the same situation - he was using an open-backed Peavy combo that had a decent speaker but a horrible amp. He disconnected the wires from the amp to the speaker, soldered himself up a connector wire with a 1/4 inch plug on one end and two speaker-clips on the other end - the 1/4 inch went in his new head's output, and the speaker clips went on the speaker of the combo. Presto! No explosion!

Now, I'm no electrician, and would never try this myself, but if you have anyone who's decent with a soldering gun and knows their way around ohms and all that fancy electrical-speak, they could probably work something up for you. If the combo you're working with is closed-back, though, it could be more of a hassle.
