For sale we have here today a Strat HH Style Semi-loaded White Pickguard With Megabucker Wiring Installed.
 
Components included herewith:
 
1. 11 holes 3 ply white H-H pickguard to fit Fender/Squire Stratocasters, etc.
2. 3 no.s of 500K CTS Potentiometers (Neck Vol., Bridge Vol., Master Tone).
3. 2 way DPDT ON/ON toggle switch (Normal / Series) activation.
4. 3 way PU selector switch (Neck/Middle/Bridge).
5. Pickguard screws.
 
With this Megabucker wiring, one can connect both the neck and the bridge humbuckers in series mode. This gives a fuller and more powerful sound compared to a conventional parallel setting (i.e.: middle PU selector switch position).
 
The series mode is activated with the flip of a 2 way DPDT ON/ON toggle switch which is custom mounted on the pickguard here (refer to operation chart in the photos).
 
After you purchase this kit, simply install both your humbuckers on the pickguard, connect them to the pre-labelled wires. Connect the pre-labelled output jack wires, and connect the existing tremolo/bridge ground wire to the base of the potentiometer.
 
Kindly PM me if you have any questions, etc. 
 
Thank you.
