Description
Swapping out a stock preamp harness is one of the fastest ways to unlock what your bass pickups are actually capable of, and the Bartolini HR4.4/918 makes that upgrade painless. This prewired harness is built around Bartolini’s respected 918 electronics, giving you dual volume controls so you can dial in the exact blend between your neck and bridge pickups instead of fighting a single master knob.
- Dedicated Volume control for pickup one
- Dedicated Volume control for pickup two
- Mid Frequency control with push/pull switch to select frequency range
- Stacked Bass/Treble control for shaping low-end punch and top-end bite in one pot
The push/pull mid frequency switch is where this harness earns its keep on stage – flip it to move between frequency ranges and reshape your midrange character without reaching for outboard EQ. Pair that with the stacked bass/treble knob and you’ve got real tonal range packed into a compact control layout, useful whether you’re chasing a fat, rounded low end for a reggae gig or a tighter, more aggressive attack for rock and slap work.
Because it’s prewired, installation is straightforward for anyone comfortable with a soldering iron – drop it into your control cavity, make your connections, and you’re shaping tone instead of troubleshooting wiring diagrams. A solid choice for bassists looking to get more expressive control out of an existing instrument’s electronics.
