I want to add a programmable gain amplifier to my Teensy-based guitar "pedal", so that I can use guitars with different pickup levels.
I already have the buffer with gain 1, so I'll put the amp right after it.
Should be low-noise and 3.3V power.
And I need it to be controlled via SPI or UART, something Teensy can do. Don't want any knobs on my pedal, only the touch screen.
Thanks.
