Description
Skip the soldering headaches and drop straight into precision EQ with the Bartolini HR4.4/918 Prewired Harness. Built around Bartolini’s respected active preamp circuitry, this harness hands you independent control over two pickups plus shelving EQ that actually gets used, not just fiddled with once and left flat.
- Volume, Volume – dial in separate output levels for each pickup, letting you blend attack and warmth exactly how you want it before it ever hits the amp.
- Mid Freq control with push-pull frequency switch – sweep the midrange center point and flip the switch to jump between frequency ranges, so you can chase anything from a scooped slap tone to a punchy, vocal-forward growl.
- Bass/Treble Stack knob – a single concentric control that lets you carve low-end thump and high-end sparkle independently, without hunting through a maze of extra pots.
This is the kind of setup players reach for when a passive tone knob just isn’t cutting it anymore – whether you’re rewiring a bass that needs more shaping power or building out a custom electronics cavity from scratch. Because it’s prewired, you’re looking at a straightforward install rather than an afternoon lost to a soldering iron and a wiring diagram.
Works across bass and guitar platforms that call for this kind of active EQ layout – check your cavity space and pickup wiring compatibility before ordering to make sure it’s the right fit for your build.
