fantastic purchase and good "bang-for-the-buck." I have previous experience w/ the SD JB; technically, the JB jr in two of my Strats. This set went to a Gibson SG Special of somewhat uncertain humbuckers; with high output and slightly scooped tone (hotter than my SG Standard's 498t, 490r.) My amps alternate at times but are essentially early-to-mid '80's classic hi-gain Marshalls (JCM 800 2204, original JCM 25/50, Lead 100 Mosfet) for heavy metal/hardcore. I love mids and this combo absolutely delivers the cut and body needed for crushing tone. If one assumes the guitar in question was loaded w/ a 490r neck pickup; then the SH-2 Jazz beats it out in clarity and snap. Either way, the upgrade is undeniable and I highly recommend anyone dissatisfied with their pickups and have a similar setup go for this set. The set straddles the line between absolute highest, cutting output and responsive tone, i.e, if you play hard, it sounds hard; if you play soft, it sounds off that way as well.
