M06078 Music Man Potentiometer – 500k Push/Push Tone, Majesty, Luke 3 (2012), JP13/15/16, Valentine Tone - 1 pc

Part number M06078 is an original 500k Push/Push potentiometer from the renowned US guitar and bass manufacturer Music Man.

The M06078 is a genuine Ernie Ball Music Man USA replacement part used as a tone control or volume potentiometer with a push/push switching function (press the knob to toggle modes). Ideal for restoring factory-spec electronics, reliable switching and the correct taper/feel for compatible Music Man instruments.

Key features:

• Resistance: 500k
• Switching function: Push/Push (mode switching by pressing the knob)
• Type: Original OEM Music Man USA spare part

Who it’s for / suitability: Designed exclusively for original US-made Ernie Ball Music Man guitars and basses. Not suitable for licensed Asian models from the Sterling by Music Man range. A great choice for players and techs who need correct, noise-free control operation for anything from clean, dynamic tones to high-gain modern playing—especially where push/push switching is part of the instrument’s stock wiring.

Where you’ll find part M06078 (known applications):

• Luke 3 – used as the tone control on versions featuring push/push on the tone knob.
• Valentine – tone control.
• JP13, JP15, JP16 – John Petrucci models with Version 1 (V1) preamps.
• Majesty – models with V1 preamps (mono/stereo switching is integrated on the piezo potentiometer).
• StingRay Short Scale – used as a push/push volume control potentiometer.

Note for JP13 and JP15 models: Before purchasing, you must open the guitar and check the electronics. If the potentiometer does not have a flexible ribbon lead (flex ribbon), it is the V1 version, which uses this M06078 part. Newer V2 electronics use different potentiometers with a flat printed circuit connection.
