Description
If you’ve been running passive EMG HZ pickups and wishing you had more shaping power without gutting your whole wiring harness, the BTC System HZ is the answer. It’s a pre-wired active EQ setup built specifically to work with passive EMG pickups, giving you real tonal control instead of just a volume knob and a prayer.
- Concentric bass/treble stack delivers roughly 12dB of cut and boost on each band, so you can go from thumpy and rounded to snappy and cutting without touching an amp.
- Master volume and blend control let you balance pickup output and overall level on the fly, mid-song if you need to.
- Every knob is center-detented, meaning you can feel your way back to a flat, neutral setting even in a dark venue without looking down at your bass.
- A dual dip-switch mounted right on the PC board lets you dial in one of four different high-frequency response curves, so you can match the top-end character to your rig and your ears.
Under the hood, this system runs on modern surface-mount tech, which keeps noise floor low and current draw light – your 9V battery will thank you. EMG’s BTC platform is one of the most widely gigged bass EQ systems out there for good reason: it’s simple to wire in, reliable night after night, and it puts real tone control in your hands instead of leaving it up to the room.
Included in the box: two concentric knobs for the bass/treble stack, plus two knobs for balance and master volume.
