The heart of this drop-in prewired Strat harness is our custom DiMarzio 5-way Super Switch made by Oak-Grigsby, configured to automatically split the bridge humbucker when combined with the middle pickup (position 2). By using parallel resistance, the single coil pickups sound like they are connected to a 250K pot, while the humbucker still sees the full resistance of the 500K pot.

This drop-in prewire harness features a combination of our custom designed 500K and 250K pots. First built over 45 years ago, we wanted the smooth feel and graduated taper found on some vintage 50s guitars. Using a 10-step rotary switch, we created a taper that works with DiMarzio pickups. Its neither a linear nor audio taper pot — it’s DiMarzio’s custom taper. To further increase reliability, we make the center shaft and threaded parts from solid machined brass instead of cheap castings.

This kit also features a Switchcraft output jack and includes both black and white switch tips for the 5-way switch.

DiMarzio wiring harnesses are all hand assembled and tested in the USA. We use the best sound-tested parts available from Oak Grigsby, Switchcraft, Sprague, and CTS, and we include vintage-style cloth wire.
