I have a Squier VI, 30 inch scale, tuned C to B in fifths. The strings are custom LaBella rounds and the low C is 120, I do not recall the others. The upper strings sound indistinguishable from a guitar really so I use them when I want to blend in with/double the guitars. I play in a worship band and for some reason it is a tradition in that culture to bring the bass in and out for emphasis. So if I want, and if I have the VI that Sunday, I can jump in with the guitars if I want to keep playing. I also have a 30 inch Ibanez SRC6 that I have pulled one string from to turn it into an SRC5. I love that thing, it is the greatest bass Ibanez never made! Even though they kinda/sorta did!! That is tuned C to E. And finally as a gimmick although it is half serious and not altogether a silly thing to do I have a Squier 51 with a four string bridge and nut. I leave two of the tuners unused and tune its mighty 25.5 inch scale G to E. So it is a baritone more than a bass but it works reasonably well when all is said and done. What I wanted was a short scale 51 Precision bass and since no one makes one but the Squier 51 bears a certain resemblance to one, I did what I had to do.... I don't recall exactly what I use for strings on the last two. I can tell you that they are regular bass and guitar strings cut down to fit the shorter scale length and tuners when necessary. I lay them out on the bass with the ball end seated in the bridge and mark where the nut and tuner contacts the string. Then I put appropriate diameter electrical shrink tubing in that area between the nut and tuner. Only after it has been shrunk securely in place do I begin to unwrap the strings to allow them to fit the tuners. So far that has worked.
