I have a great tele style guitar with buttery, super low action and sweet bone nut cut and installed by a fantastic local luthier. However, I want it primarily to play slide guitar in open tuning. With such low action I have to play slide with a lot more finesse that I'm used to / expected as the low nut kinds of make the guitar a bit vulnerable to rough-and-ready slide noises with the occasional choking of notes. This is the nut: Should I have a new nut installed or revise my technique? I know that some players get away with low action when playing slide but I guess I need to practice more.... BTW rising the action at the bridge makes very little difference, especially at the first 5 frets, whilst making it too high at the 'dusty end'. What do yo think?
