By 'combine' I mean plug them up and together to where they both play at the same time.
I have a Marshall MG Series 30DFX amp with a footswitch input, a guitar input, a line-out input and a microphone input.
I also have a Peavey 5150 half stack
...unfortunately it only has a high gain guitar input, low gain guitar input and an FX Loop input.

Basically,
I want to take a few guitar chords, plug them into each amp to where when I turn both amps on, I hear both amps playing.

Anyone have some ideas as to how I can do this?
ANY IDEAS would be helpful.

Thanks,

Marshall

No offense, but if you have a 5150 half stack why would you want that cheap Marshall queering up your tone? If the Marshall doesn't have a line in, as you described and the Peavey has an effects loop, you would have to use the Marshall's pre amp to drive the 5150 by running the Marshall's line out into the 5150's line in of it's FX loop. Your 5150 would sound like a loud version of the cheap Marshall. If the Marshall had a line in, you could use the 5150's preamp to drive it and it would probably sound better, but the Marshall doesn't have a line in. My advice would be if you absolutely want to run both, get an AB box. The guitar goes into it and it has two jacks out, one to each amp. Usually you can use the box to select either amp or both. My actual advice is to use the 5150 and keep the Marshall for a practice amp. :wink:

Aside from the sonic qualities differences of both amps, if you want to connect one guitar to two amps, you either use a A/B/Y switch, like this one: http://www.morleypedals.com/daby.html
or you take a stereo effect pedal, like this one: http://www.bossus.com/index.asp?pg=1&tmp=15
and connect one output to each amp.

A multi-effects processor with stereo output will do the same also, but you might need a special cable with a stereo 1/4 jack at one end and 2 1/4 jack mono at the other end.

Properly setup, you can have a cool stereo sound, using both amps.

I'll take all of you guy's advice. Thanks.
So, aside from bying an A/B Switch, there's no way I can rig my 5150 up to where I can hook it into my computer?
What about plugging the FX Loop on my 5150 to my computer via 1/4" to 1/8" adapter?
Just curious.

I just went to Peavey and looked up the manual on the 5150 head. On the backside of the amp you have a "Preamp Out". This is the proper output to use. This is a "line" signal.

Not ever really running my guitar or amps into a computer can't give you advice on that, but I'm sure others could tell you.

But use the Preamp Out.

Yep! What he says (Wes Inman), use the Pre-Amp Out (for computer use), otherwise you'll fry everything.

So you want to record direct to your PC the 2 amps at once?
I fail to see the purpose.
You can simply record one after the other and mix the tracks to have the same effect.
(actually, even probably better as you'll be able to individually adjust each sound)

Probably the best and easiest way to record both amps at the same time is to connect each amp's output to a little mixer (like this Behringer http://www.behringer.com/UB502/index.cfm?lang=ENG ) then the mixer output to your soundcard.

I come out of my first amp into a dummyload whih has numerous outs. Also most of my rack mounted equalizers what numerous outs also. There are many different pieces of equipment that will allow you to run both amps at the same time. The trick is gettng them adjusted to create a sound that will have folks wondering.
