Was chatting with a friend this morning and he suggested that when our band finally gets a new PA, I invest in a direct box for my bass, to send the bass signal directly to the PA, since I just use a combo amp right now, and I would like to have more volume for outdoor shows, etc. He gave me a link for this: http://www.americanmusical.com/item--i-RLL-DB25.html Would the above item work, or would I need something else? Are there issues I'm probably not thinking of? Keep in mind I've always just played through my amp in the past, so this is all new territory for me. My understanding is that I'd still connect my bass to my pedal board to the combo amp, then send from the line out on the amp to the direct box, which would go into the PA. Thanks in advance.
