Welcome, you are looking at a great piece. This is the DiMarzio DP155 Tone Zone Pickup. Wiring: 4-conductor lead wire. Magnet: Alnico 5. DC Resistance: 17.31k Ohm.
The DiMarzio Tone Zone is a high-output pickup with a wider dynamic range than standard high-output humbuckers.
The DP155 is extremely responsive to picking dynamics for playing that is full of nuance and expression.
The Tone Zone has wide bass and low-mid response that reinforces the bottom end and makes the overall sound bigger. And the patented dual-resonance coils reproduce more overtones that are usually lost in such a full and fat sounding pickup.
We are an authorized DiMarzio dealer. Don't pass this by.
