You can expect the practically identical sound of a real Fender 54 Strat pickup but with more presence from the high plain strings.
They produce a very nice twang (slightly less aggressive than the other Impersonators), noticeably scooped midrange and very nice high note bite and bloom ... more so than other Strat pickups. Better dynamics and note separation than a real 54 Strat and more bounce from the E-6th low wound. Authentic Position 2 & 4 Knopfler-esque ‘cluck’ sounds.
Extremely versatile, from Hank Marvin's 60's Shadows instrumental tunes to Yngwie Malmsteen. It's also good for other musical genres (including Jazz) where a slightly smoother Stratsound with nice bite and presence work magic.
