Product Code: EMG BQS HZ system

The EMG BQS HZ System is a top-tier active electronics solution meticulously engineered for the modern bassist. Tailored specifically for instruments equipped with passive pickups (such as the EMG HZ series), this system offers unparalleled control and tonal depth. As a high-quality 3-band equalizer, it provides separate, dedicated controls for Bass and Treble, paired with a specialized stacked parametric mid-range potentiometer. This unique design allows you to sweep through the frequency spectrum and boost or cut your chosen target frequency, giving you precise command over your bass's voice.

Engineered with an ultra-low noise floor and exceptional headroom, the BQS HZ ensures your signal remains pristine even when pushed to its limits. Because it utilizes the acclaimed EMG Solderless Install System, this preamp is not only sonically superior but also remarkably easy to install – requiring no soldering. Whether you are using a 4, 5, or multi-string bass, the BQS HZ system provides the special combination of passive warmth and active power, delivering the articulate, punchy sound that defines a modern professional instrument.
