Same here. Different times I like different combinations. With this particular guitar and pickups - as of now I hear a more complex, dynamic and interesting sound with round wound strings.
it feels a little presumptuous of me but I’m going to start bringing both my 575 (or550) and the chambered Millie to gigs for different vibes. We typically do a mellower
classic jazz set then a more upbeat groove second set, so a move to the Millie between sets seems fun.
