Frequently asked questions
Which pickup goes in which guitar type?
The STK-S7 is designed for standard Stratocaster single-coil cavities. The SP90-1n is a P90 soapbar and requires a guitar with P90 routing (typically semi-hollow or offset designs). They are not interchangeable.
How do the output levels and breakup character differ?
The STK-S7 has higher DC resistance (11.97k) and delivers more muscular output with aggressive natural breakup, while the SP90-1n at 8.22k ohms is more dynamic and touch-responsive, favoring clean articulation that breaks up more gently with pick intensity.
Which one is better for blues?
Both excel in blues, but the STK-S7 emphasizes warm lows and mid presence, making it ideal for traditional Strat-based blues. The SP90-1n offers brighter treble definition and tonal transparency, suiting modern or jazzy blues approaches.
Are both wax potted and noise-free?
Yes, both pickups are wax potted to eliminate microphonic feedback and squeal. Both deliver stable, quiet operation suitable for intermediate to professional players in any setting.
