Hardware
PickupsJennifer Neck Humbucker
A PAF-inspired neck humbucker with warm mids, smooth highs, and a full low end. Intentional tolerance control preserves vintage character with dependable output.
EffectsRange Master
Built around a limited stock of original OC44 germanium transistors, this treble booster restores clarity and brightness to early amplifier circuits.
EffectsBoing Boing Reverb
A digital recreation of vintage 1960s spring reverb with warm bounce, harmonic richness, and a useful range from restrained space to deep ambience.
Effects62 Drive
Rare 1980s JRC4558D chips add smooth, transparent gain while retaining the natural identity of the guitar and amplifier.
InstrumentERT-1 Guitar
A materials-led instrument with lightweight alder, quartersawn maple, a hand-applied linseed oil finish, and EGR X pickups and wiring.
EffectsJerry Fuzz
Vintage LM308 op-amps produce a thick low end and stable distortion, reducing harsh highs while preserving grit and warmth.
AmplifiersEverDrive Special
A small-batch, hand-built amplifier tuned through measurements and real-unit A/B listening for headroom, smooth nonlinearity, and exceptional touch response.
The EGR X definition of high end
Luxury is control.
Not ornament for its own sake, but a musical result made deliberate: the right material, the right geometry, the right circuit, and a repeatable standard of finish and support.
Acoustic fit
Materials are selected for the instrument and response, not for cost or rarity alone.
Controlled tolerance
Geometry, winding, impedance, and component values are matched as one system.
Evidence and listening
Parametric models and lab measurements meet blind player evaluation.
Finish with purpose
Machining, plating, oil finishing, and assembly protect performance as well as appearance.
Long ownership
Serial tracking, a standard warranty, global fulfillment, and lifetime technical support.
Pickup voice guide
Choose by response, not by hierarchy.
Output is one part of the decision. Position, magnet system, winding, instrument density, amplifier headroom, and playing touch all matter.
| Model | Format | DCR | Voicing |
|---|---|---|---|
| Ladyfingers | Single coil | 5.5 kΩ | Low distortion, clear chords, sweet clean response |
| Autumn Chill | Single coil | 6.0 kΩ | Forward mids, bright articulation, warm lows |
| Golden Bell | Single coil | 6.3 kΩ | Bell-like high-end definition, rounded mids |
| Jennifer | Neck humbucker | 8.0 kΩ | Warm PAF character; covered or open-coil |
| Night Drive | Bridge humbucker | 9.0 kΩ | Vintage warmth, modern clarity, stronger gain |
| Sure | Tele set | 6.5 / 7.5 kΩ | Fast transient, focused upper mids, clear attack |
| Peach | Tele set | 6.2-6.4 / 7.3 kΩ | Vintage foundation, naturally balanced pair |
| Annabelle | Tele set | 5.8-6.0 / 6.4-6.6 kΩ | Bright, open, extended headroom |
The EGR X method
Metallurgy, measured.
Premium material is only the beginning. Geometry, density, damping, impedance, and the instrument itself have to work as one acoustic system.
Design the interaction
Parametric structures are developed around resonance, mechanical coupling, playing feel, and repeatable production.
Control the process
Integrated CNC machining, precision metalwork, plating, and molding keep tolerances and surface treatment in-house.
Test beyond the bench
Lab measurements are paired with component matching and blind player evaluation across multiple instrument types.
Build for consistency
Findings return to the design loop, creating products with dependable tone, fit, durability, and traceability.

Instrument dossier / ERT-1
The system, made playable.
Lightweight, long-air-dried tonewood and a thin hand-rubbed linseed oil finish preserve an open acoustic response. A quartersawn maple neck, single-action truss rod, optimized pocket angle, and complete EGR X electronics system carry that response into the amplified voice.
