Greetings, I have used TI Jazz rounds for years on various basses and love them. I put them on a new J bass and neck moved a lot. Seems like very low tension to cause that movement, I also had a hard time setting the neck relief for the TIs. Put on a set of Elixir Lights 45,65,80,100 the neck was fine however too much tension for my liking but they sound great. I also have a set of Elixirs Medium on my P and 44-02 Lakland and have no issues with the tension. I can't figure out the problem. Main Question; is there any other low tension strings you all can recommend but not as low as the TI Jazz.
