    Hi, can anyone help me?
    I am working on a guitar tuner based upon porzio's circuit.(pcb construction and hex/asm code) I would like to eliminate the 6mm audio jacks so that it is soley based upon the microphone input. In addition because of space constraints is it possible to change the battery size but maintain the voltage/current necessary. Porzio's current circuit relies on 4 AAA, but if possible can i reduce that to one triple A or a 9-volt.
    the modified circuit is below
    any help would greatly be appreciated

    The two links do not work. The circuit you posted looks ok. What was the function of the parts you removed?
