The Perfect P90 for a Single Pickup Junior! | Ron Ellis in a Grez Mendocino Jr
Ron Ellis Pickups returns to the channel with a P90 bridge pickup, installed in the Grez Guitars Mendocino Junior. Welcome back to Edge of Breakup.
The Ron Ellis P90 bridge pickup — installed in the Grez Guitars Mendocino Junior with Emerson Custom Prewired Kit, 500K pots, and Treble Bleed on the volume pot — runs into the Benson Amps Vincent 2x12" with Scumback H75-PVC speakers. The Expresso FX Beige Dual Ge/Si Fuzz and Ge Boost and Effectrode Tube Vibe both feature.
The Ron Ellis P90 brings Ron's molecular-level materials research to the soapbar format — the same engineering approach he applies to his humbuckers, delivering clarity and dynamic touch response rather than the raw, uncontrolled midrange some P90s are known for. Paired with the Mendocino Junior's compact offset body, the result is articulate and expressive across clean, pushed, and cranked amp tones.
The Expresso FX Beige Dual Ge/Si Fuzz and Ge Boost is a two-circuit pedal from Sof, built in the UK with zero compromise on components. The Fuzz Face-style side is switchable between three transistors — NOS CV7005 germanium, NOS OC202 silicon, and NOS AC188 — giving three distinct fuzz voicings from a single circuit. The Ge Boost side uses an NOS OC45 germanium transistor — the same transistor found in the earliest Dallas Rangemaster units — delivering classic treble booster character.
The Emerson Custom Prewired Kit's Treble Bleed keeps the P90's clarity intact through the full volume knob sweep, and the Effectrode Tube Vibe rounds out the demo with rich, three-dimensional modulation.
