Frequently asked questions
Can I use the BTS HZ System on a bass?
The BTS HZ is designed as a guitar preamp for passive pickups. The Stacked control set is purpose-built for bass and extended-range instruments, especially those with active electronics or multiple pickups requiring blend control.
Do I need to buy additional components with either system?
The BTS HZ is a complete preamp that integrates directly into passive-pickup guitars. The Stacked control set comprises three potentiometers that require integration with an existing or planned active electronics harness.
Which offers more tone-shaping flexibility?
Both deliver ±12dB bass and treble control. The BTS HZ adds a 2-position dip switch for high-frequency slope adjustment and operates at variable voltage (9–27V) for headroom tuning. The Stacked set prioritizes pickup blending and integration with active preamps rather than tone-stack flexibility.
What noise floor should I expect?
The BTS HZ specifies 120dB input-referred noise with 18V operation. The Stacked control set is described as low-noise and designed for EMG active electronics, which typically match or exceed that performance in active systems.
