I have owned a number of sires and a number of Musicman products (Stingrays, Ray34, USA subs olp, SUB 4 and 5's, sterling (the model)) The Z7 comes up and i like what i am seeing. Its a potentially best of both worlds buy, but in these days of few and far opportunities to try i'll watch the review and go for the even more musicman like Z3 or the Z7 and just buy one 'blind'  (return policy applies here btw..).  It will be intersting how it sits soundwise next to my Lakland 55-02 (same pickup
