Does anyone have experience or recommendations on how to interface an analog electric guitar mono signal to the Teensy 4.0 Audio Shield?
Audio shield "Mic" input or "Line In" input or Teensy A/D input?
Impedance matching circuit, etc?
Thanks

I used both with an ATMega1284 with a +5v supply but the MCP6001/2/4 data indicates a power supply range of 1.8V to 6.0V, and the TL97x family operates at voltages as low as ±1.35 V.Would you power the OP Amp with 3.3v or 5v?
