This quality 3-ply Black AweSome Upgrade product is for your standard right-hand Fender Classic Series '72 Telecaster Deluxe HH guitar with two Wide Range Humbucker pickups. This product gives you More pickup tones on your upgraded instrument.
This drop-in, no body routing product has everything you need to install into your standard right-hand Classic Series '72 Telecaster Deluxe guitar. This upgrade pickguard has 15 holes to attach it to your guitar.
Instruments That Can Be Upgraded
You can upgrade the following instruments:
- '72 Telecaster Deluxe Reissue
- American Professional Telecaster Deluxe Shawbucker
- All similar "clone" instruments with 15-screw attaching pickguard holes
Note: On some models, you may need to redrill mounting holes, remove pickguard material or body cavity material. Purchasing this AweSome Upgrade means that you are OK with, and accept that possibility.
Your instrument contains two Wide Range Humbucker pickups. These two coils on these pickups are somewhat asymmetric (see discussion below.) Although they can be configured as 4-wire versions, the manufacturer set them up as 2-wire versions.
We include two lengths of 4-wire shielded cable so you can easily convert your Wide Range Humbucker pickups from their "stock" 2-wire version to a superior 4-wire version.
The following AweSome Upgrade variations and options are available for this instrument:
(the "no pickups" versions let you save money using your own pickups)
(the "pickups" versions come complete with pickups.
- T4 (no pickups) - you install your own 4-wire humbucker pickups to get 68 pickup tones.
- T4 (with pickups) – you connect your input jack wires and drop it in to get 68 pickup tones.
How It Works
Using Our T4-Switch
The other version of our AweSome Upgrade uses our T4-Switch to control your two Wide Range Humbucker pickups that you have altered to become 4-wire versions.
(this is also how our upgrades that include pickups work)
Here is how the mini-toggle controls of our T4-Switch product are laid out.
There are really two "groups" of switches:
(SW1, S5B, SW2) -and- (SW3, S5N, SW4)
(control bridge coils) (control 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).
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. Pretty simple, don't you agree?
When switches S5B and S5N are in the Down position, you will get 29 different pickup tones from the various combinations of four pickup coils being Off or On (either in normal-phase or in reverse-phase) using switches SW1, SW2, SW3 and SW4. These pickup tones are also due to the combination of pickup coils being in a Parallel circuit.
The other switches (S5B and S5N) are ON-ON (a.k.a. ON-NONE-ON) switches are used to put select pickup coils into a Series circuit. Here are two things you must remember when putting pickup coils into a Series circuit:
First, putting two pickup coils in 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 of the affected pickup coils that are in a Series circuit 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
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 (south neck) pickup coil (down is normal-phase, up is reverse-phase, center is Off.)
Switch S5N: Puts both (neck) pickups into a Series circuit when Up. Both pickup coils MUST be On.
Switch SW4: Turns on (north neck) pickup coil (down is normal-phase, up is reverse-phase, center is Off.)
The Tone control push-pull pot puts the north bridge and south neck pickup coils into a series circuit.
For this product, the Tone control push-pull pot puts the north bridge and south neck pickup coils into a series circuit. This gives you 20 additional pickup tones, several of which are QuadraBuckerTM pickup tones (all four pickup coils in series).
In summary, the various combinations of all of these switches and the push-pull tone control will give you 88 pickup tones.

This switching system cannot be used with active (battery-powered) pickups or pizeo pickups.
Active (i.e., battery-powered) pickups manufactured by Bartolini, EMG, Seymour Duncan, etc. will not work with our growing family of high performance patented Pickup Switch UpgradeTM products. These active pickups use a design that prevents any of the pickups from being put into series because it sends -9VDC back to the first pickup, shorting out the circuit. Although some manufacturers now sell "add on" products to give you some of the functionality that our products automatically provide, this design limits their versatility and increases the cost to the musician. Many people who have tried these products remove them because they are "too sterile sounding". Anything that uses batteries will likely go dead at a crucial time - like when you're performing or in the recording studio. Bill Lawrence was right when he said, "Batteries belong in flashlights."
