From Michael Kelly:

"Pinnacle basses are built around playability. Maple and walnut are layered to create a rock-solid five-piece neck, with diamond inlays and glow-in-the-dark side markers adding a special touch to the rich ebony fretboard. The deep cut lower horn offers easy access to the upper frets. The diecast MCN4 bridge allows individual side-to-side saddle adjustments for variable string spacing by up to 1.5mm to optimize the instrument to your playing preferences. An exposed spoked truss rod wheel at the base of the fingerboard makes any needed adjustments quick and easy.

The Pinnacle 4 is able to create that perfect tone, whether in a concert performance, recording in the studio, or simply knocking out tunes in rehearsal. The two custom-wound Rockfield MDC4 humbucker pickups provide a modern, fat sound with potent midrange punch, or can be coil-tapped with the dedicated switches to deliver a more airy, classic tone. The push-pull Master Volume knob engages the active preamp, where the MK Custom 3-band EQ offers easy shaping of the instrument’s sound, while selecting the passive mode calls up an authentic “old-school” tone. This custom blend of electronics makes the Pinnacle a versatile instrument for any bass player."
