Product overview This control circuit provides precise bass and treble shaping for instruments with two pickups. It uses B50K potentiometers and is specified for use with Pickup MN250K. The circuit is intended for installation where P1 is wired with the neck pickup positive and P2 is wired with the bridge pickup positive. If you are not familiar with soldering or wiring guitar electronics, please consult your local luthiers for installation. Key benefits Clear tone shaping: Bass and treble controls give dependable boost and cut so you can tailor the instrument sound to the room or recording. Predictable performance: Component values and frequency points are specified for consistent results across installations. Designed for two pickup setups: Explicit wiring orientation for neck and bridge pickups reduces ambiguity during installation. What it does and why you need it Bass and treble control: Provides +/ 10 dB adjustment at the specified frequencies to correct or enhance low and frequencies without affecting the overall pickup balance. Improves tonal flexibility: Lets players quickly adapt their sound for different musical styles, live stages, and recording situations. Ensures proper phase and wiring: Clear P1 and P2 polarity guidance minimizes wiring errors that can cause phase cancellation or incorrect signal routing. Specifications Potentiometer type and value: B50K Pickup reference: MN250K Bass control: +/ 10 dB at 30 Hz, B50K Treble control: +/ 10 dB at 6 kHz, B50K Pickup wiring: P1 should be with neck pickup positive; P2 should be with bridge pickup positive Configuration: Intended for use with two pickups Compatibility and fit Intended for guitars or instruments using two pickups where the specified pot values and pickup model are compatible. Requires wiring that places neck pickup on P1 and bridge pickup on P2 to match intended polarity and control behavior. Practical use scenarios Live performance: Use the bass and treble controls to adapt the instrument tone to different venues and PA systems, reducing the need for repeated amp adjustments. Studio recording: Fine tune low end and presence to sit the instrument better in a mix, using the specified dB ranges to make predictable, repeatable adjustments. Upgrade or : or upgrade the existing control circuit in a two pickup instrument while retaining standard B50K pot behavior and MN250K pickup compatibility. Installation note Wiring polarity matters. P1 should be wired with the neck pickup positive and P2 should be wired with the bridge pickup positive. If you do not know how to install the circuit, consult your local luthiers. Performance expectations Bass range provides up to 10 dB of boost or cut centered at 30 Hz for low frequency shaping. Treble range provides up to 10 dB of boost or cut centered at 6 kHz for frequency presence control. Using specified B50K pots ensures consistent linear response as designed.
