Description

Introducing the Harley Benton MP-4MN, where precision meets playability in an artful fusion of classic design and modern functionality. This electric bass is the ultimate companion for both seasoned performers and budding bassists. Crafted with an ergonomically shaped body of swamp ash, it offers a pleasing resonance and lightweight feel that enhances playability during long gigs or practice sessions. The eye-catching 6-bolt Canadian Hard Rock Maple neck provides exceptional stability and comfort, while the sleek Modern "C" neck profile ensures a smooth ride across the fretboard.

Equipped with Roswell pickups — the MFR-4 Ferrite humbucker at the bridge and the PM-4 Ferrite single coil in the middle — this bass delivers a wide spectrum of tonal possibilities. Whether you’re in the studio or on stage, the Roswell GMA2 active/passive 2-band EQ enables you to tailor your sound with precision. The push/pull volume control offers seamless transition between active and passive modes, making it a versatile choice for any musical style.

With 22 medium jumbo Blacksmith stainless steel frets under your fingertips and a maple fingerboard adorned with striking black block inlays, every note sings with clarity and sustain. The black TUSQ XL nut, WSC SK4 bridge, and WSC JB45 tuners ensure impeccable tuning stability and intonation, so you can focus on what truly matters: your music.

Features and functionality

    Source

Mods and upgrades

  • Owners are considering upgrades like Hipshot tuners and Fender Roger Waters pickups for enhanced performance, indicating potential for significant customization.

    Source
  • Users suggest that several aspects of the bass may require upgrades to reach the desired sound quality, implying potential additional costs.

User experience

    Source
