Installed for a few weeks and removed; some light scratches on chrome cover under A/D strings, but ZERO impact on function and tone. 4-conductive lead has more than 12" of wire; red/white leads already soldered together with heat-shrink tubing for most applications... but easily changed if you need special wiring for phase reversal, etc.

Overall VG+ condition, no returns, and priced accordingly. Feel free to ask any questions about installation or how it sounds; YouTube video link below was helpful for me.

Info from the Railhammer pickups website:

With rails under the wound strings for tight clear lows and poles under the plain strings for soaring highs, Railhammer humcutters deliver that venerated P90 tone without any of the hum.

"Nuevo 90" neck pickup: Vintage P90 tone for today’s player.

Classic vintage P90 sound, but tone and volume optimized for the neck position. All the fat lower mids, raw attack, and greasy goodness you’d expect, upgraded with the tonal balance and enhanced response of the Railhammer design. Perfect for blues, classic rock, old-school punk, or any player looking for that vintage P90 vibe, but better.
