I'm wondering about using a small mixer to conect the three guitars I use in my gigs into the same amplifier. So, I don't have to be plugging and unplugging my guitars every time I switch.
I this a good idea or is there a better way of doing this?
I've seen a few mic mixers, like the BEHRINGER MX400:

But they are all active and require some power... thus, more cables and hassle. Have you ever seen a pasive one and, if possible, designed for guitars?
Thank you!
