Mystery Device

[Hornbag]

Heya, my friends dad has this nifty device which allows multiple inputs to one amp, like four guitars leads go into this little black box and then only one cable comes out of it into the amp. I was wondering if anyone knows what these are called, cause my next gig I'll probably need two basses and switching input lead onstange can be a tricky business, as my rhythm guitarist found out. I'd appreciate any info.

Thanks

You might check Rolls for a small line mixer.

I've got one of these: http://www.sweetwater.com/store/detail/AB2/



it's very useful. you can have 2 guitars plugged in, and switch between both of them. makes switching on stage really easy, just as long as you remember to press the switch.
