Is it hard to set up alternate tunings on all standard tremolo systems, or just the ones on strats? What I mean mean by hard is that as you are tuning each sequantial string, it seems the other string you just tuned either goes up or down in pitch, thus having to go back through each string until all the strings are tuned properly. It takes a while to fully tune it. Once it is in tune it stays though. I am deciding between a guitar with a stoptail and one with a tremolo right now, and that is one of the main selling points, easy alternate tuning capability (as well as sustain, but that's another story). Any knowledge on this? Thanks.
