Hi, can anyone help me?
I am working on a guitar tuner based upon **broken link removed** circuit.**broken link removed** 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?
