This wiring diagram for a 4-way or 3-way toggle switch works with any pre-amp or passive-mode Musicman Stingray bass. Enjoy your 1-Parallel, 2-Single-coil Neck & Phantom, 3-Series, (and possible 4-Single-coil Bridge) bass configurations again. The 2.2k resistor keeps the Series config volume...

You can also use a 3-way toggle switch to get configurations: 1. Parallel (Coils 1 & 2), 2. Neck & Phantom Single-coil and 3. Series (Coils 1 + 2). The 2.2k resistor is needed in the series circuit to reduce the volume boost due coils 1 & 2 (2kOhms/each) in series. This toggle switch set-up...

Just had a John East MMSR Preamp installed on my Musicman Stingray5 fretless and it's fantastic with tons of new sounds given the true mid-sweep (200HZ-2KHz) and mid cut/boost stacked pots. I used a 4-way toggle switch to achieve 1. Parallel, 2. Single-Coil (Neck & Phantom), 3. Series, and 4...

Also, why is it said that the MMSR 4k3B preamp NOT work with original Musicman Stingray5 3-coil pickups? Is it because of the coil resistance of 1.95kOhms on each coil?

Greetings John-- Where is the revised documentation for this thread concerning a passive full bypass wiring for the MMSR preamp? Please advise or send directly to my email. Thanx.
