So the G string on the Sadowsky set just broke. Right at the ball.
In my frustration, this just occurred to me: Was the TI low-B weak and muddy because my nut slot wasn't big enough? I found the original specs of my bass, and it was factory-strung with a .125 on the bottom. The TI low-B is a whopping .136! I did notice that I had to press the string a bit further than usual on the first few frets, which made it a bit of a strain to fret those lowest notes.
I can order a .130 nut file from allparts. (I've filed nuts on my guitars, and I know how to file a bigger slot than the file spec.)
So did I jump the gun in writing off the TI's? (I hope so. Cuz I really miss the tone!)
