Description
Wiring in a new preamp is one of those jobs that eats an afternoon and tests your patience. Bartolini’s HR4.6/918 harness handles the heavy lifting for you — every pot, the 918 pre-amp, and the connections are already assembled and ready to seat in your control cavity. That means less time hunched over a soldering iron and more time actually playing the bass you just upgraded.
Tone-wise, this is Bartolini’s 3-band setup, built around control layouts bassists actually use on stage: a Volume/Blend pair for balancing pickups on the fly, plus a Treble/Bass stack and Mid control with push-pull switching between two frequency points on the mids. That flexibility lets you dial in a fatter, rounder low end for a dub-style groove one night and pull back the mids for a punchier, cut-through-the-mix tone the next — without ever touching an amp knob.
Bartolini has been building pickups and electronics out of San Luis Obispo, California for decades, and every unit is 100% USA-made. Their gear shows up in instruments from top luthiers and is a go-to for shops handling upgrades and repairs — which is exactly the kind of trust you want in something wired directly into your bass’s signal path.
