Take the can and press it against you're bass skin, my bass skin was resting or 2 things so there was nothing in the middle. Viola, you have a nice clean cut hole. Easily done. You could also just go buy one of those holes that you can trace with a box cutter.
Ooh sounds dangerous...but i guess i could try that. Sounds like it works. Thanks
