T4 Upgrade Wiring
This Black acrylic Jazz Bass Upgrade is for 4-pickup coil instruments. It gives you 68 pickup tones.
Now you can Soup Up your Jazz Bass to get more pickup tone power and also increase your creativity and versatility with dozens of additional fresh new pickup tones.
Your stock bass is designed to give you a modest and inadequate 3 pickup tones. Don't you think it's worth a few dollars more to get a Grand Canyon Wide range of 68 Blues, Jazz, Metal, Surf, Country plus the dozens 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.

"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 3-way switch 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

This upgrade uses our T4-Switch.
There are two "groups" of switches:
(SW1, S5B, SW2) -and- (SW3, S5N, SW4)
(control bridge coils) (control middle and neck coils)
Here is how the switches are used:
Switches SW1, SW2, SW3 and SW4 are ON-OFF-ON switches used to turn an individual pickup coil Off and On. The middle position of each switch is Off. The down position turns the pickup On (in normal-phase) and the Up position turns the pickup On (in reverse-phase).
When you use these four switches (with S5B and S5N in the Down position), you get 29 different pickup tones from the combinations of four pickup coils being Off or On (either in normal-phase or in reverse-phase). It is also due to the combination of the pickup coils being in a Parallel circuit.
Switches S5B and S5N are ON-ON (a.k.a. ON-NONE-ON) switches that are used to put select pickup coils into a Series circuit when in the Up position. When Down, the select pickup coils are in a Parallel circuit.
Here are two things you must remember when putting pickup coils into a Series circuit:
First, putting two pickup coils in a Series circuit creates a "Compound" (i.e., Humbucker) pickup that gives you about 8 to 15 percent More output (think Heavy Metal/Jazz tone).
Second, because the pickup coils are in a Series circuit, BOTH pickup coils that are in Series MUST be On (either in normal-phase or reverse-phase). Any non-Series circuit pickup can be either Off or On (either in normal-phase or reverse-phase).
What Each Switch Controls
(this example uses two 4-wire humbucker pickups)
Switch SW1: Turns on (south bridge) pickup coil #1 (down is normal-phase, up is reverse-phase, center is Off.)
Switch S5B: Puts both (bridge) pickup coils #1 and #2 into a Series circuit when Up. Both pickup coils MUST be On.
Switch SW2: Turns on (north bridge) pickup coil #2 (down is normal-phase, up is reverse-phase, center is Off.)
Switch SW3: Turns on (middle) pickup coil (down is normal-phase, up is reverse-phase, center is Off.)
Switch S5N: Puts both (middle and neck) pickups into a Series circuit when Up. Both pickup coils MUST be On.
Switch SW4: Turns on (neck) pickup coil (down is normal-phase, up is reverse-phase, center is Off.)
The various combinations of all of these switches will give you 68 pickup tones.
