I never really thought there was that big of a difference. The guitar I had for years was an Ibanez RT with V7 and V8 pickups. I was like alright, they sound ok. I didn't have anything to compare.
Then I got an RG with IBZUSA pickups and they sounded a little better.
Then I got a JP50 from Sterling with Crunchlab and Liquifire. I played that for a while and then went back to the RT. WHat a difference.
Yeah, the V7/V8 sound much better
