From around 1980-1992 I tuned to Eb. Since then I've been at standard A440 for since it makes it easier to teach students, work with different bands, etc. I've been considering tuning to Eb to be able to play around with some of my favorite artists songs and even considered tuning a whole step down to mess with some Robin Trower. I'm curious what others here are doing. I've also used a hybrid gauge string set (09-46) for a long time. Not sure if I would keep these or go up to standard 10's. I realize it's a personal decision but just curious.
