![]() ![]() The honk factor can vary based on the type of pickups used. It’s common to place the J in classic ’60s Jazz bridge position (polepieces centered at 3.75" when measured from the back end of a standard Fender bridge plate), which gives the individual pickup a fuller sound-but the proximity to the treble coil of the P pickup (about 1.25" closer than on a Jazz setup) can emphasize a midrange honk that some find unappealing, particularly for slap. On the other hand, as you place the J pickup closer to the neck, its volume will increase. To achieve this relative spacing, the J pickup will bump right up against the bridge plate, and will sound thin on its own. If you’re hoping to get a J Bass-type tone from a P/J setup, first take into account that the P pickup is hotter than a neck-position J in a different location, and the pickups on a ’70s J are spaced approximately 4" apart center to center. Distance = toneĪnother ingredient in the blend is how close the pickups are to each other. FENDER PJ BASS WIRING DIAGRAM PLUSAn added plus of a stacked or split-coil J is the elimination of 60-cycle hum from an unpaired single-coil pickup. Assuming a certain amount of expected output loss due from proximity to the bridge, you can see why it might match up well with DiMarzio’s Model P pickup, which is rated at 163mV. 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. ![]()
