Description

Some gigs call for a scooped, hi-fi low end with headroom for days. Others just want your bass to sound like a bass, no batteries required. The Bartolini HR4.6AP/918 harness lets you have both without touching a soldering iron on install day, since it comes fully pre-wired and ready to drop into your control cavity.

At the heart of it is Bartolini’s 3-band preamp, wired into a control layout built for real-world playing: a Volume knob with a push-pull Active/Passive switch, a Blend pot, a stacked Treble/Bass knob, and a Mid knob with its own push-pull for switching between two frequency centers. That’s a lot of tonal ground covered from four knobs, whether you’re carving out room for a mix or just want to fatten your low mids on the fly between songs.

Runs on 9V or 18V, and the kit includes what you need to go either route:

  • 3-band EQ preamp with Volume/Blend and Treble-Bass/Mid controls
  • Push-pull Active/Passive switch on the Volume pot
  • Push-pull 2-frequency switch on the Mid control
  • Second battery clip for 18V operation
  • Wiring instructions
  • Black ring and center knobs for the tone stack

Bartolini builds every one of these harnesses in San Luis Obispo, USA, using premium audio-grade pots that hold up to years of load-in, load-out, and everything in between. If your bass needs a real upgrade in tonal range without a redesign of your control cavity, this harness gets you there.
