For example, the DiMarzio Ultra-Jazz DP148 is a split-coil bridge-position J pickup with a claimed 250mV output. Before you buy anything, think about your goal for the pickup blend-do you want the J to stand up to the P as an equal, or subtly blend in with it? Do you intend to solo the bridge pickup regularly? How much volume drop is acceptable?Īs most single-coil J’s are overpowered by the P pickup, one solution is to look at a split-coil or stacked humbucker in a J-size case. This is why many manufacturers make their bridge position J hotter than the neck position pickup. Magnetic pickups sense vibrations, but since the string vibrates side-to- side less near the bridge, the result is a lower signal. The culprit at work here is string excursion. While the P’s and J’s relative output specs are important, keep in mind that placing a pickup closer to the bridge will also decrease the overall volume. And then some manufacturers measure pickup output in millivolts. In general, the greater the inductance, the greater the output and greater the bass response.”Ī commonly listed pickup spec is dc resistance (measured in ohms), and while this figure often coincides with output, variables such as wire gauge can make this number misleading when relating to output. Master pickup builder Jason Lollar describes inductance as “a measure of the physical property to induce a current. One such number is the pickup’s inductance, measured in henries.

The pickup’s output is an important detail, and as manufacturers are not uniform in how they present specs, there are three figures you can examine to help you determine a pickup’s output. The perfect blendīeyond adding Jazz burp to your Precision thump, you have to consider how the pickups will blend, and there are several contributing factors. That said, there are a few things to consider before you venture into P/J territory.
