Hello, Last gig I had issues listening myself live on stage so I´ve decided to find a solution. My idea is to use a device this way: bass connected to the device, and from the device 2 outputs: 1 for headphones with volume knob and another one to the bass amplifier. It has to be a small device so I can put it on my belt or on on the bass strap, and have the chance to use batteries to avoid a power cable hanging on stage. The 2 options I dig by preference are these: ART Pro Audio ART Pro Audio The first one I see the input is a Mic Input, not instrument, so I don´t know if it would work. The second one maybe is a bit too big/heavy for the use I need. Any experience/recommendation/alternative? Thanks in advance!
