Ok all, here goes. I recently joined a cover band which does some classic rock, old country, but mostly newer top 40 country stuff. Once I started looking into some of the songs i realized that some of the bassists are using 5'ers. So, i went on a search and purchased a great active deluxe jazz V from a fellow Tb'er which I just got today. On a couple of the songs, the guitars are in drop C# (drop D down half step). I know the bassist (Tully Kennedy of the Jason Aldean band) is strictly a 5 string player. I learned those songs on my P bass played in drop C# and they were pretty straight forward. My question is, when it comes to re-learning these songs on a 5'er, should I keep it in standard tuning and just re-learn the positions or do I tune everything down a half step and just learn the positions needed on the low B string. The bass is set up for standard tuning and obviously the C# i need is there on the B in standard tuning. If this an incredibly stupid question then I apologize in advance. Any help is appreciated.
