Journey Instruments upgradeable EP001K 3-Piezo Passive Balanced German Pickup

The EP-001K Passive piezo pickup is an elegant pickup solution for transparent tone to amplify the natural sound of your acoustic guitar. Installation requires no modification to your guitar apart from drilling the endpin jack hole and gluing the elements to the bridge plate. (Note: If installing on a guitar with narrow x-bracing under the saddle, such as a Martin Jr or Taylor GS Mini, we instead recommend you go with the EP101KM)General Specs and Details:3 balanced German-made ceramic piezo elements - 20mm diameterStandard 1/4 inch (6.3mm) mono output jack2.5mm mono input jack from piezo elementsno batteries neededlength of wire from peizo element to pickup jack: 22cmfrequency response 22Hz-18kHzEADGBE guitar frequency range is E2 (82 Hz) to F6 (1,397 Hz)impedance under 1 M?Installation Guide At Manufacture's SiteNOTE: As this is an endpin jack, you may consider buying our Journey Guitar Strap which is slit to fit this endpin.
