I live in NC, but don't know of any EBMM dealers who have an AL with MM90s. I too would love to try one. I just finished playing my MM90 ASS for about three hours, and I love those pickups to death.
Indoor Storm is THE dealer here in the Raleigh area. They currently have an Albert in SSS configuration, and a JP6. They HAD a Luke last week, but it followed me home.
GuitarHack is correct.........Indoor Storm seems to be the only dealer that usually has one or two in stock. Even the GC's don't have EB guitars in stock. I wish there was a better presence of EB here.
