yesterday i decided to hook up an old alesis multimix 8 usb between my boss rc 300 looper and my amp. I plug my looper into one channel and my bass into another. This allows me to control the volume of the bass and looper separately through one device. I also use headphones through the alesis because my amp doesnt have a headphone jack and using the headphone jack through the looper actually sucks because the bass peaks out creating imbalance between the drum samples Im getting really clean sound and the alesis surprisingly has nice effects that i use on the bass channel. I've never seen a mixer used in this way and was curious if anyone else does this. My other question is how does phantom power work? It sounds logical but i cant seem to get it to work.
