This pickup comes with a 2.5mm jack on a 22" lead. The pickup is 4 1/4" at it's widest and 5/8" tall with a depth of 1". The magnetic magnet provides excellent output volume and a great hard driving acoustic sound.
These are very resistant to feedback when used properly and plug into any of our GFS endpin jack preamps with no modifications. You may also use them with any our GFS acoustic preamps that feature a 2.5mm piezo input jack.
