Tone Stack for Guitar Amplifier Reference Design
TIPD186
Overview
This split-supply, high-performance guitar tone circuit provides control of the bass, mid, and treble frequencies of an electric guitar signal, while also providing gain with minimal distortion and noise. Buffered inputs and outputs preserve the behavior of the system independent of the source and load impedances, and a radio frequency (RF) filter on the circuit front end attenuates noise from outside the audio band.
Features
- THD+N at 1 kHz: -105 dB
- Treble adjustment range: 10 dB
- Mid adjustment range: 9 dB
- Bass adjustment range: 19 dB
- Supply voltage: ±15 V
- Utilizies OPA1642 high-performance, JFET-input audio operational amplifier
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
