Hey, Im looking at possibly buying an Eden Nemesis NC410 4x10" combo, the 320 watt version. It only has one instrument input. I'm wondering if you can use the regular input for my bass, while at the same time running a drum machine thru the effects return? We use a drum maching alot during practice, and usually run it thru my amp, which right now is an Ampeg BA115 with 2 inputs, one for the bass, the other for the drum machine. Previously did the same with a Mesa Scout (had to sell for financial reasons), and a Roland DB500, (sold also). It didn't work on the Roland, but I know on some amps you can do this. So before I buy....does anyone know if this can be done with the Nemesis NC410?
