I'm new to PRS and new to this forum. I've just bought an SE Bernie Marsden and have seen lots of call for replacement tuners and folks seem to like the Gotoh SD90 MG locking tuners. It looks from Gotoh's website that there are a few varieties of this tuner (short/long/extra-long) so can anyone tell be the exact model to get for drop-in replacement on the BM? I'd also be interested in the SD90 MG-T with the preferable-to-me large locking "dial"... Thanks in advance.
