SH1. Standard switching with 3 positions, no splitting, Megaswitch T
This is the simplest standard switching system for guitars that have a single coil on the bridge and Humbucker on the neck. The switch has 3 positions and operates the bridge both parallel, and the neck. Each has its own tone control. The Megaswitch T is ideal for this application.
If you want to use this circuit in a guitar with only one tone control, then connect this to the right stop of the volume control (or contacts 4 and 8 on the Megaswitch T).

SH2. Five positions with Humbucker splitting, outer coil, Megaswitch E+
This switching system is for guitars with a single coil on the bridge and a Humbucker on the neck. The Humbucker can be split while the outer coil remains active. The inner coil is short-circuited. The Megaswitch E+ is ideal for this purpose. Position 3 is buzz-free when the magnetic polarity is configured as follows: S-SN or N-NS.
If you want to use this circuit in a guitar with only one tone control, then connect this to the right stop of the volume control (or contacts 3 and 4 on the Megaswitch E+).

SH3. Five positions with Humbucker splitting, inner coil, Megaswitch E+
This switching system is for guitars with a single coil on the bridge and a Humbucker on the neck. The Humbucker can be split while the inner coil remains active. The outer coil is short-circuited. The Megaswitch E+ is ideal for this purpose. Position 3 is buzz-free when the magnetic polarity is configured as follows: N-SN or S-NS.

SH4. Five positions with switching in series, Humbucker splitting, outer coil, Megaswitch M
This switching system is for guitars with a single coil on the bridge and a Humbucker on the neck. It allows both pickups to be switched in series which creates a louder, fuller tone. The Humbucker can be split while the outer coil remains active. The inner coil is short-circuited. The Megaswitch M is ideal for this purpose. If a buzz-free sound is required in position, the following magnetic polarity (from the bridge to the neck) is required: N-NS or S-SN.
If you have a guitar with two tone controls (type "Stratocaster"), then just leave one unused.

SH5. Five positions with switching in series, Humbucker splitting, inner coil, Megaswitch M
This switching system is for guitars with a single coil on the bridge and a Humbucker on the neck. It allows both pickups to be switched in series which creates a louder, fuller tone. The Humbucker can be split while the inner coil remains active. The outer coil is short-circuited. The Megaswitch M is ideal for this purpose. If a buzz-free sound is required in position 2, the following magnetic polarity is required: N-SN or S-NS.
If you have a guitar with two tone controls (type "Stratocaster"), then just leave one unused.
