I'm curious about the Stack Plus pickups. They're supposed to sound the same (or very close) as their non-stack counterparts, but they have a much lower resonant peak.
SSL-1 Resonant Peak 10KHz
STK-S4 Resonant Peak 5.7KHz (neck/middle) /5.2KHz (bridge)
SSL-5 Resonant Peak 6KHz
STK-S6 Resonant Peak 4.85KHz
So how can they sound the same?
