✔ Warmer Tone

Clearer Pickups

Piezo crystals are shifted 90 degrees to reduce inharmonic overtones.

Better Sounding Frets

The hardness and weight of the Pepperoni Frets offer longer sustain, stronger fundamental frequency, and cleaner vibrato.

 

Revoiced Tone Filter

Warmer than the previous generation.

Sweetened Scale Length

 Shorter scale for a sweeter tone.

✔ Smoother Play

Improved Feel

Large-radius frets feel better with fast slides and provide better dynamics with higher action at the first fret and lower action at the highest fret.

Smoother String Bending 

The harder and larger radius frets create less friction for string bends and vibrato.

Custom Knobs

New teardrop knobs with visual/tactile indicators now repositioned to avoid accidental bumps.

Optimized Note Range

 Plays 3 semitones higher than the K24, offering a more useful range from C1 to C6.

✔ Sleeker Look

Shine & Precision

Machined Pepperoni Frets offer stunning shine and precision.

Hand-Painted Accent Plates 

Tortoise finish with embedded logo.

Refreshed Logos

Updated to mark the evolution of the product, with the bridge logo relocated to the wrist rest for a cleaner, more sophisticated look.

Richer Natural Finish

 Wood toner tailored to bring out the natural hues of birch, maple and bamboo.

✔ Simpler Care

Durable Frets

Pepperoni Frets offer superior hardness, wear, and corrosion resistance, extending fret life and reducing cleaning needs.

Stable Tuning

Saddle guides improve tuning and intonation.

Action Adjustment

Two topside screws replace four underside screws for easier action adjustments.

Easier Tuning

 The floppy lowest string and breakage-prone highest string were eliminated. Additional frets were added to fill out the note range.

New Pickup Design


The harpejji M5 pickups have been completely redeisgined to optimize consistent tone across the instrument. The piezo crystals have been reoriented 90 degrees to reduce inharmonic overtones.

Pepperoni Frets


Not only do Pepperoni Frets look and sound better, they feel buttery smooth under your fingertips. Pepperoni Frets are made with a proprietary alloy for maximum durability and hardness.

Revoiced Tone Filter


We've revoiced the tone filter to have an overall warmer tone. We've also updated the volume and tone controls to tactile control knobs and relocated them to the side of the instrument.
