JAM Classic — 2026 Version

Minimal-mass offset bridge with uncoated V-Rail® brass saddles for maximum touch, openness, and color.

Immediate attack and open, airy dynamics via direct acoustic coupling, with precise control and wide radius adjustment; CNC-machined from solid stainless steel and brass.

JAM Classic – who it’s for
Players prioritizing pure tone on fixed or non-gliding setups (e.g., offset builds without vibrato travel across the saddles).

Quick features

• Custom locking mechanism for secure bridge fixation
• V-Rail® brass saddles with compensated grooves for all string gauges
• Widely adjustable radius(7.25"–20", 12" preset)
• Precise left/right alignment of overall string position
• Bridge base milled from a solid block
• Bare brass for direct string-to-saddle contact

---

Sound characteristics

• Open, airy, highly responsive
• Immediate attack with articulate highs
• Lively harmonic bloom with natural warmth
• Clear separation and wide dynamic range

---

Performance & tuning stability

• Positive bridge lock prevents drift and micro-rattle
• V-Rail® saddles: tight, safe string contact
• Radius adjustable from 7.25" to 20" for perfect board matching

---

Reproducibility guaranteed

All parts are precision CNC-machined from purpose-selected, custom-spec materials for:

• Top dimensional accuracy
• Perfect planar contact surfaces
• Dense, non-porous structure (no air-inclusion artifacts)

---

Aged overnight (optional)

CRYO-treated (overnight deep-cooling) to relieve residual manufacturing stresses, aiming for a more vintage-like, settled tone and “played-in” feel.
