EMG BQC System vs EMG BQS System
The BQC System offers superior battery life (750 hours vs. 170 hours) and lower noise floor (-120dBV vs. -96dBV), making it better for extended touring and session work where consistent power and transparency matter most. The BQS System adds a dedicated fifth knob for easier access to balance control and includes center detents for tactile reference, suiting players who prioritize ergonomics and quick tone recalls during live performance.
No sales tax on orders shipped outside California — total cost beats national retailers that charge sales tax in nearly every state.

Why choose EMG BQC System
- ✓ 750-hour battery life—ideal for multi-week tours and extended sessions without frequent battery swaps
- ✓ Lowest noise floor at -120dBV input-referred noise for maximum signal transparency
- ✓ Higher recommended voltage headroom (18V standard, 27V max) for greater dynamic range
- ✓ Lower current draw (740µA @ 18V) extends battery performance across long sessions
Why choose EMG BQS System
- ✓ Dedicated 5-knob layout with pre-wired balance control for faster, more intuitive operation
- ✓ Center detents on all controls allow you to find neutral by feel without looking
- ✓ More compact interface reduces accidental parameter drift during live play
- ✓ Slightly lower bass control sensitivity (±10dB vs. ±12dB) prevents over-processing low end
Frequently asked questions
Which system has longer battery life?
The BQC System delivers 750 hours per charge at 18V, while the BQS System provides 170 hours at 9V. The BQC is substantially better for touring and full-day session work.
What's the main operational difference between the two?
The BQC uses four concentric knobs (Bass/Treble paired, Mid Boost/Mid Frequency paired) while the BQS uses five separate knobs with a dedicated balance control and center detents on all controls. The BQS layout is faster to adjust by touch.
Which has a cleaner signal path?
The BQC features lower input-referred noise at -120dBV versus the BQS at -96dBV output noise, giving the BQC a significantly quieter signal floor for studio and high-gain applications.
Are the EQ ranges the same?
Mostly—both offer ±12dB treble and ±12dB mid with 100Hz–1KHz sweep. The BQC offers ±12dB bass at 20Hz while the BQS offers ±10dB bass, giving the BQC slightly more low-end control.
