I'm having a tad bit trouble cutting the mix in my garage band. The reason is because I share my amp with our keyboardist. I think that it's a good thing that I know WHY this is so, but figuring out a way to bypass it has been a hassle. I play a 1996 Fender '75 Reissue Jazz Bass. The strings are pretty new (bought the bass off eBay for Christmas, came with new roundwounds). I have a Behringer 60W amp that I bought brand-new during the summer. We play in a big greenhouse in the middle of nowhere, so I doubt acoustics are the main problem. What should I do to cut the mix properly enough?
