JMJ Mustang Bass Upgrade

T2P-Switch Wiring

Product Description

This black acrylic upgrade is for your JMJ Road Worn Mustang Bass with a "P" pickup. This upgrade will give you 4 pickup tones instead of just one pickup tone.

Now you can Soup Up your JMJ Road Worn Mustang Bass to get more pickup tone power and also increase your creativity and versatility with additional fresh new pickup tones.

Your stock bass is designed to give you a modest and inadequate 1 pickup tone. Don't you think it's worth a few dollars more to quadruple the range of new and different pickup tones your stock bass simply cannot produce?

This EZ Install high performance upgrade gives you the ultimate in performance at the lowest cost.

Customer Comments:
"After installing this upgrade in my bass, I stayed up all night playing it." — Alvin Sears

"I am SO pleased with the upgrade. The standard volume blend controls is an 8-pack of Crayolas when compared to your upgrade which is the 98-pack with built in sharpener. I now have colors I didn't even know I wanted. Do I need EACH of the additional tones? No, of course not; but there are many new tones which, now that I have heard them, I cannot live without. The next time I buy a bass, your products will be that instrument's first upgrade!" — Branden Garner

To Install This Upgrade

Simple pickup rewiring is needed with this upgrade. You will cut the wire that connects the two "P" coils and attach extra wire (supplied) using the included solderless terminal connectors. This separates the "P" pickup into two separate pickup coils. Use an ohmmeter to confirm that the wires connected to the pickups read continuity. Once rewiring is completed,

  1. You connect your pickup wires to the green solderless terminal strip (see picture)
  2. You connect your bridge ground wire to the marked wire on this product
  3. You re-attach the upgrade and start exploring all the pickup tones now available to you.

Using This Upgrade

This upgrade uses our T2P-Switch.   More... >














How The T2P-Switch Works

The T2P-Switch contains two mini-toggle switches (from rear-to-front): (SW5, SW3)

These switches are used to control the Bridge (coil-1) pickup, and the Middle (coil-2) pickup coils.

SW5 is an ON-ON switch used to put the two pickup coils in either a Parallel connection or Series Connection. Down is Parallel, and Up is Series.

SW3 is an ON-ON switch used to change the phasing of the two pickup coils (i.e., coil-1 and coil-2). Down puts the coils in normal-phase and Up position puts the pickup in reverse-phase.

You get 4 pickup tones with this upgrade.   < Less
