I finally have the right gear (key) for adjusting the string action on my avatar photo guitar (the bridge has 6 saddles, so each string on its own saddle). Action I prefer is around 2 mm and previous owner had it way over 3mm. And while I was adjusting the action and playing after that a question pop up. Should all strings have to have the same action or can some be higher and others lower in order to achieve the best "feel" when playing - and by that, I mean just minor differences not huge ones. On my lower strings I think that 2 mm is spot on, but maybe just a hair more on higher (thinner) strings. So my question is, do you have the same string action on all strings or not?
