Most of the time when you buy strings for your bass it's pretty easy to get the correct length. If your scale length is 34" then you buy "long scale" strings. Sometimes it's not that easy, though. What if you string through the body? What if your bass is just a little different than most? I have an Ibanez BTB 4-string that is 35" scale and top-loads into individual bridges. I figured it needed XL strings but those turned out to be too long and I had to sell them at a loss because you generally can't return opened strings. I'd like to have us compile a list of manufacturer's string winding length (the distance between the ball end and the silk/taper) as a reference. I figure XL's and Long Scale lists should suffice, unless you know of odd scale shorter basses. XL's Sadowsky: 39" Ken Smith: 40" Long Scale Sadowsky: 37 1/4" E, 38" other strings. Ken Smith: 38" DR: 37.5" Can you add to either list?
