The new B4FL MHPZ was designed and developed for fretless bass players who need to get a more "acoustic" bass sound to go along w/ a great fretless electric bass sound and feel. Get the best of both worlds in one versatile instrument that provides a multitude of excellent sounds and superb playability.


The Blackwood top on chambered Mahogany body w/ the F-hole exudes a classy look while delivering a deep, organic and punchy low-end sound.


The Jatoba fretless fingerboard plays super smooth and true and has black markers for fret positions that will surely be appreciated by novices as well as experienced players.

Bartolini MK-1

The trademark Bartolini sound is preserved in the MK-1 while providing superb sound quality and value. The MK-1 delivers plenty of punchy and warm mids along w/ transparent and brilliant highs for a superbly balanced sound.

Hipshot Ultralite Tuners

B4FL MHPZ is equipped with Hipshot Ultralite Tuners (classic 20:1 tuning ratio) that is made of cast zinc with aluminum strings posts and mounting nuts, resulting in 30% weight reduction over other regular tuners and which results in improved balance and tuning accuracy.

Thumb Rest

The thumb rest has been carefully placed on the body surface to allow the bassist to easily employ the right-hand finger-picking techniques.

Fishman Power Bridge

The Fishman Powerbridge piezo pickups provide a very natural acoustic tone from the bass that can be used alone or in conjunction with the passive electric bass pickup.

2 Volume & 2 Tone Control

The two volume and two tone controls facilitates individual and independent use of the traditional electric bass pickup and piezo pickup sounds or for a blend of the two to the player’s taste for exceptional tonal versatility.
