So I'm upgrading the humbuckers ect. in one of my earlier guitars I've owned, I think I bought it like early 2001,02? B.C. Rich Warlock. My first sick looking guitars and have alot of memories with it so I've kept it through the years. Fast-forward to today, I have other waaaay better guitars now but I still like to pick this one and up amd shred so decided to upgrade the humbuckers and such from the original Jackson hardware. Went on ebay and bought Seymour Duncan's HB1 set...they benefited a charity so I thought win win...well I got them today and they are "Duncan Desined" HB103...they so looked like USA brand in the pics but fine print does label them as "Seymour Duncan designed". My question, are they still an upgrade from the old Jackson humbuckers or did I just basically donate to charity and need to buy the real Duncan's for the upgrade? Thanks for feedback.
