Just a quick question, didn't find anything on the search. I have a Little Mark II that I usually have running into my berg HS410. I also have a guitard that I'll play through it. I have friends that come over and want to throw down a quick -LOW VOLUME- jam.
Is it feasible to hook up my Peavy Mark IV(the second input is busted) along with the Little Mark II into the 410?
I wanted to ask you techies before I melt my speakers  |

What you could do would be to take the pre-amp out put of several sources, mix them in a mixer, and send that to the power stage of a single amp.
You could also just get a second cab and be done.

They'll just have to stick with acoustics cause I ain't buying an amp just for them. |

| | | | No.
Since the plugs on the cabinet are wired parallel, it would be like plugging one amp directly into the other amp.
Does the LMII have a blendable effects loop? If your guitar friend has a pedal of some sort, that may be a way for both of you to play.
The more educated about these matters will give better advice...

Don't do it!!!!!!!!

He had a 40 watt peavey combo that he used as a head for his Marshall half stack. I only had a 15 watt Crate practice amp and couldn`t be heard over the drummer let alone everybody else so we had the great idea to plug my little 15 watt into the half stack ALONG with the 40 watt. It worked for a minute or 2 and then I saw the little red power light on my amp get real bright and then go out. My buddy`s amp killed my crappy amp. Oops.
I wish I had the interweb back then......
