Practicing guitar with stereo music and guitar amp is not practical in many housing or populated areas. It sounds great when you get the chords right with song. Neighbors lack patience on this method. This circuit mixes audio tune and guitar track to hear on headset.
Top left audio input and lower right headphone output are 1/8 inch connection jacks. Lower left jack is regular 1/4 inch guitar jack plug.
