I owned 6 jv basses all 57p and if you allow my experience, though they are great basses, they cannot compare to the 57 av ri.
All av 57 ri i played and the one i own are outstanding basses in tone, wood selection and playability.they are top notch and are in my oppinion custom shop quality basses.
If your heart desires that much for the 57av ri, go for it..you will not be disappointed.
Honestly, i think after you went familiar with the new bass, you will smile about the rw and you will be happy,
That you have done that.
