Do you use the same bass to practice as you do to perform? Being pretty new to the bass and playing out, I was just wondering if it is common to use a bass for practice and rehersal only and one for performance only. I play a 60's Classic Jazz at our church service and an 80's Japanese Jazz for practice and rehersal. They play and sound very similar, but the J Jazz is pretty beat up and the 60's Jazz is mint. I even put a T-shell pickguard on the J Jazz so they look alike. I do use the good one for practice occasionally to keep the feel of it.
