So here is the deal I have a 1550m and 2570vsl and I am looking to upgrade both sets of pick ups. I have an x2n and air norton I want to put in one and then so a set of bareknuckles in the other. I am originally thinking to upgrade the 1550m first as it has the v7/v8 versus the 2570 having the Dimarzio/ibz. What do you guys think? i know alot of people might think the x2n and air norton wont balance but I already have an X2n and if it doesnt work I will be going to something like a tone zone or crunchlab.
