Description
EMG BQC System
The EMG BQC System is a compact, battery-powered active electronics package engineered for studio and session work where surgical control over instrument tone is non-negotiable. This four-knob configuration delivers real-time equalization sculpting through an intuitive layout that tracks player input instantly, letting you dial in your tone during tracking or re-amp sessions without introducing noise or compromising headroom.
Precision EQ for Recording & Mix Integration
The BQC offers comprehensive equalization with ±12dB treble control, ±12dB bass control at 20Hz, and a sweepable mid-range control spanning 100Hz to 1KHz. This three-band architecture lets you address specific frequency ranges with precision during recording—tightening low-end mud before it hits tape, adding presence in the upper midrange to cut through a dense mix, or sculpting the fundamental character of your source.
Studio-Grade Signal Path & Transparency
Exceptionally low noise at -120dBV input-referred noise ensures your signal remains transparent and clean in the mix, even at high gains or through multiple recording passes. The system operates efficiently on 18V recommended supply (27V maximum) and draws only 740 microamps at 18V, delivering approximately 750 hours of battery life per charge cycle—substantial runtime for extended sessions and recording days.

Frequently Asked Questions
What is included in the BQC System?
The system includes the main electronics module, 2 concentric knob sets (for dual-function controls), 2 single non-concentric knobs, a battery clip with bus connector, a stereo output jack with battery switching, and 4 interconnect cables for wiring integration.
How long does the battery last?
At 18V recommended supply, the BQC draws only 740 microamps and delivers approximately 750 hours of battery life per charge cycle—roughly 31 days of continuous use. The system supports up to 27V maximum and maintains low current draw for extended touring or session schedules.
What skill level do I need to install and use the BQC?
The BQC is designed for intermediate to advanced players and professionals. Installation requires basic soldering and wiring knowledge; use is straightforward thanks to the four-knob layout (master volume, balance, bass/treble, and mid boost/frequency controls).
What frequency ranges can the midrange control adjust?
The sweepable midrange spans 100Hz to 1kHz, allowing you to dial in presence in the lower or upper midrange depending on your instrument and tone goal. Combined with ±12dB treble and bass controls at 20Hz, you have comprehensive three-band EQ.
How does the BQC compare to other EMG active systems?
The BQC offers surgical, three-band EQ with a noise floor of -120dBV and extended battery runtime, making it ideal for session and touring work. It differs from the SPC and EXG in its dedicated mid-sweep control and comprehensive tone-shaping architecture designed for transparent, low-noise signal management.
Do I pay sales tax on this order?
We collect sales tax only on orders shipped to California. Orders shipped to any other US state are charged $0 sales tax at checkout when you buy direct from our website. On this item that is roughly $14 less out the door than the same listed price at a national retailer or on a marketplace.
