Description
The HR3.4/918 is Bartolini’s answer to bassists who want serious tonal control without rewiring their control cavity from scratch. This pre-wired harness pairs Bartolini’s respected 3-band preamp with audio-grade potentiometers, so every knob feels smooth and stays that way after years of gigging.
Layout-wise, it’s built to be economical with real estate: one hole handles a stacked Neck Volume/Bridge Volume control, while a second pair of holes covers a Treble/Bass stack plus a separate Mid knob — the Mid control includes a push-pull switch for selecting between two frequency centers, letting you dial in anywhere from a scooped slap tone to a punchier mid-forward growl.
Because it’s designed to run on either 9V or 18V power, you get the option to boost headroom and dynamic range simply by wiring in a second battery — Bartolini includes the extra battery clip needed to make that jump.
- 3-band EQ preamp, switchable 9V/18V operation

Built and supported entirely in the USA, this harness drops straight into most instruments needing a Bartolini-standard 3-band voice with minimal wiring headaches.
