Hi just a quick question regarding input/output impedances for audio circuitry.
It seems like voltage transfer is pretty important as in the case of a preamp at least as you are taking say an op-amp or JFET with a much larger input impedance as compared to the output impedance of the guitar.
For audio at least, when would you care about power transfer through matching input/output impedances?
Through reading "Electronic Projects for Musicians" by Craig Anderton, he states in the Appendix that most often matching impedance for maximum power transfer is desired but voltage transfer is becoming more important and a rule of thumb is to have an output impedance 1/10th of what the input impedance being fed is.
Wondering what your thoughts are.
