Those little Slammer SB4's are really great as is, especially with flats. Tons of deep, robust low end out of 'em. I really like the necks on those, in fact, I'm getting ready to have a luthier buddy of mine reshape the headstock on one of those into a shrimpfork and set it into a mahog special body with a single X2N. I'll post some pics as the project develops. (maybe I should drop in those T-Bird pups I got from you;}) Really nice basses, Andy!
