Great upgrade for my P-Bass

Installed this last weekend. The noise reduction is incredible compared to my old passive setup. Highs are crisp.

Professional tone

Using this for studio recording. The active preamp gives me the headroom I need. Very satisfied.

Quiet and punchy

No more 60-cycle hum. The mid-range control is very useful for cutting through the mix.

Good value, tricky install

Sounds amazing once hooked up. The wiring diagram could be clearer for beginners.

Solid component

Potentiometers feel smooth. Battery compartment access could be easier, but overall a great harness.
