So, this is odd and I'll probably get some people that hate what I am doing but I assure you, it's for a good reason. In addition to a bunch of other bands, I play in a metal band that uses extended range guitars. Specifically, 8 stringers tuned to F#. So, the riffs they mostly play have a huge open F# string presence. So, I need to have my bass tuned F# B E A D, etc. I think tuning to an F# below a low B is ridiculous and inaudible. So, What I have been doing is the following: Bass One: Low B, F#, B, E on a 4 string P Bass. The F# being an E string that I tune up a whole note, as well as the higher B tuned up from an A string, etc. You can think of it as Drop B tuning, if I was using C# tuning as a standard, I guess. Bass Two: F#, B, E, A on a 4 string P bass. Same idea here. E string tuned up to an F#. It's basically normal strings on a four string, tuned up a whole step. I know this is a little strange maybe, but it works pretty well for this band and it's tuning. THE PROBLEM: My basses kinda play like ****. I am sure string gauge has something to do with it. I am using 45-95's. I think the B on the first bass is a 130? I forget. So, do I need a bass with a longer scale? What gauge should I be using? Should I not be using Fenders? Would a Bass XI work? I'll listen to any piece of advice or opinion. Thanks!
