I play DB and BG and I use a radio pack for both. I'm looking at putting both the radio receivers into a small flight case that can sit on my amp. I will run them both into the same input lead but will have a switch to select one or the other. Rather than label the switch DB and BG or something similar, I want to use an illustration of each. Does anyone have a nice illustration, or line drawing, of a bass guitar that they could send to me please? I've looked on the net but can only find cheesy clipart... Any help is appreciated.
