Thanks all !
For those who are using Vortex and Warmoth necks with non-locking tremolos:
- would you mind showing me how the nut looks like on your neck ?
- do you use the tremolo on it, and if so do you have tuning stability issues as soon as you use it ?
The only way I got my Soloist/Vortex build with Wilkinson VS100N to stay in tune was eventually cutting the nut like Gibson does which leaves as little thickness as possible at the top of the nut:
Anything else, including the Warmoth-cut nut (and the dozen I made similar to it), was disastrous in terms of tuning stability. The other Strat I built with the same tremolo but Strat neck/6-inline locking tuners was rock solid even with heavy whammy bar use.
