Description
EMG BTS Control — Separate Bass/Treble Preamp
The EMG BTS Control is a dedicated two-potentiometer preamp module engineered for recording and mixing scenarios where independent frequency shaping is essential. Its dual center-detented pots offer tactile, repeatable adjustment across the bass and treble spectrum, making it a straightforward drop-in for active or passive pickup systems alike.
Design & Build
This unit separates bass and treble control into two distinct potentiometers rather than stacking them concentrically, eliminating crosstalk and simplifying hands-on operation during tracking and overdubs. The center-detented design provides a physical reference point for quick return to neutral, practical for maintaining consistency across multiple takes and session recalls.
Audio Performance
The BTS Control delivers ±12 dB of gain or attenuation across its frequency range, with the bass control anchored at 20 Hz and treble control offering adjustable high-end response via a dual-dip switch that selects from four different frequency settings. Input-referred noise measures −120 dBV, keeping the signal chain clean even at moderate to high output levels; the 1 MegOhm input impedance and 2K Ohms output impedance ensure transparent integration with both active and passive pickup architectures.
Key Features
- Separate bass and treble potentiometers with center detent on both
- ±12 dB gain/attenuation range
- Bass control frequency: 20 Hz
- Treble control frequency: adjustable via dual-dip switch (4 settings)
- 1 MegOhm input impedance
- 2K Ohms output impedance
- Input-referred noise: −120 dBV
- Compatible with active and passive pickups
- Recommended supply: 18 Volts DC (max 27 Volts)
- Current draw: 600 µA @ 9V / 740 µA @ 18V
- Battery life: approximately 750 hours
- Programmable high-end frequency response via dual-dip switch
The EMG BTS Control excels in home-studio setups where surgical EQ control and reliable performance matter—recording sessions, bass overdubs, and active-pickup configurations all benefit from its straightforward topology and low noise floor.

At a Glance
The EMG BTS Control delivers surgical bass and treble shaping in a clean, low-noise preamp module—ideal for tracking and mixing sessions where you need transparent, repeatable EQ without signal degradation. Its center-detented pots and −120 dBV noise floor make it a reliable choice for layering guitars in the mix, and the programmable treble frequency (via dual-dip switch) adapts to different recording contexts and pickup voicings. Use it to shape fundamental bass response and bright air independently, keeping your recorded tone articulate and sitting perfectly in the mix.

Frequently Asked Questions
What does the center-detent feature do?
The center-detent on both potentiometers provides a tactile, physical reference point at the neutral position, allowing you to quickly return to flat EQ during live work or studio tracking without guessing.
Can I use this with passive pickups?
Yes. The BTS Control is compatible with both active and passive pickup systems; its 1 MegOhm input impedance and transparent signal path ensure clean integration regardless of pickup type.
How much boost or cut does each control provide?
Both the bass and treble controls offer ±12 dB of gain or attenuation, with bass anchored at 20 Hz and treble frequency adjustable to four settings via a dual-dip switch.
What is the noise performance like?
Input-referred noise is −120 dBV, keeping your signal chain clean and transparent even at moderate to high output levels.
What power supply do I need?
The recommended supply is 18 Volts DC (maximum 27 Volts); at 18V it draws 740 µA and delivers approximately 750 hours of battery life.
Do I pay sales tax on this order?
Sales tax is collected only on orders shipped to California; orders shipped to any other US state are not charged sales tax at checkout when you buy direct from our website. Marketplaces collect sales tax as the facilitator in most states, so the same listed price can cost more there. Buyers remain responsible for any use tax their state applies. Free US shipping and 30-day returns are included.
