This Krell Fretless represents the expressive potential of ACG's craftsmanship applied to fretless bass. The Turkish Walnut top with black veneer creates a stunning visual while the swamp ash core delivers classic tonal warmth and resonance. Walnut fret lines and dots on the ebony fingerboard provide visual reference points while maintaining the singing, vocal quality that makes fretless bass so compelling. The addition of Graphtech Piezo saddles in the Hipshot Type A bridge adds another dimension of tonal possibilities, from acoustic-like textures to cutting modern tones—and the ACG EQ01 filter preamp tames the piezo's naturally aggressive character beautifully, allowing you to dial in everything from subtle acoustic color to full upright-like growl without harshness.

AC RFB Humbucker:
This hum cancelling pickup uses coils which are rotated through 90 degrees with magnets inside them placed against a single blade of steel running the length of the pickup. This gives the advantage of hum cancelling while still maintaining the narrow magnetic aperture of a single coil. The bridge and neck versions have different gauges of wire and number of turns giving added versatility to the sounds you can get from your ACG bass. The RFB Pickups represent a more open, high fidelity tone giving a great balance throughout the register of the bass guitar. The included coil switching provides additional tonal flexibility.
