The Artec EPP is an endpin with a miniature preamp inside for a soundhole or piezo pickup of an acoustic guitar.
It takes a 2.5mm input jack from either a piezo or soundhole pickup. The pickup plugs straight in inside the guitar and the amplified signal is produced at the other end straight to the cable (standard 1/4 inch).
Requires a 9v battery (supplied) to run.
Supplied with 9v battery (UK only), wire clip and sticky pad.
