On the Switcheroo Wiring Scheme:

Can't decide between series/parallel or series split wiring? Now you can have both with our new Switcheroo!

How it works: 

With the blower switch in the off position, each pickup switch flipped downward turns on the pickup wired in series.

When each pickup switch is flipped upward, you get either split or parallel depending on which function you have assigned to the upward position of each pickup switch.

To assign function:

On the front of the guitar turn the blower switch off (up) and the pickup switches up. Turn your guitar over and remove the control cover on the lower back. This will reveal three micro switches. Flip switches up to assign split; down for parallel.

What is Series/Parallel or Series/Split? How do they sound?

Series/Parallel or or Series/Split refer to the internal wiring of a pickup. Each humbucking pickup is actually made of two coils of wire. When you shut one off you have split, or a single coil. Series links the two coils together creating one long single path. Parallel connects the two coils as two separate single paths. Series and parallel are both hum canceling.

"Side by Side" humbuckings in series sound powerful, full and rich--the traditional sound of these pickups. Parallel sounds thinner and brighter, and split replicates a single coil sound.

"Over Under" humbuckings produce a rich single coil type sound when wired in series. Parallel is thin, bright and clear. Split is an even richer, full bodied single coil sound.

The 4-switch system on our guitars is quick, simple and extremely versatile:

Pickup Switches: Each pickup switch has an off and on switch. Off is the middle pickup position. Flipping the switch down turns on the pickup wired in series. Flipping the switch up turns on the pickup wired in either parallel or split. (The parallel or split function is assignable--see above).

Blower Switch: The blower switch flipped up to the off position, allows the pickup switches to function as described above. Flipped down to the on position, the three pickup switches are bypassed and the bridge pickup is turned on full power (series).

Example: For a great rhythm sound you decide to have the neck and middle pickups on split. When it's time for a powerful sounding solo, you simply hit the blower switch and play the solo with the bridge humbucker full power (series). When the solo is over, merely flip the blower switch off and you return to your multi-pickup rhythm sound.
