Yeah I think at some point the SB1 got the thinner SB2 neck or something? Either way it has a lovely profile and a deep golden gloss finish. I really appreciate the micro tilt facility on bolt on necks, too. Enables perfect adjustment.
Rather liking the cobalt flats, too. Can be tamed nicely with the tone and vol knobs, they feel great (low tension - I went for the lightest) and very full sound. I haven’t used TI flats for a while but I’m sure I prefer these.
