I've got a peculiar question as to the possible setup of an Ibanez BTB 406 bass. I currently have it tuned B E A D G B, and have experienced much fun with the range of notes less a half step due to dropping the high C). I though about the possibility of getting a hip/drop clutch placed on the lowest string, but figured there would be not much of a point because I don't need to go any lower than B. Now, hypothetically, if I were to get a lighter guage of strings for my bass, a set of heavy ernie ball 4-strings (.115-.50) then get a 35 and a 27 for the next strings, could I tune the bass E A D G B E like a guitar, and throw on a drop/hip clutch on the E to drop down a fifth to B, and alternatively if I tune the low E down to a D, still be able to drop the string to an A without tuning problems? Any advice would be greatly appreciated, as well as any solutions. Thanks.
