Bob Kilgore’s Harmonic Capo could be the Accessory of the Year. Unlike a conventional capo the Harmonic Capo has six individual rubber pads that rest gently on the strings at the 12th fret. This light resting action produces harmonics. When you fret notes below the Harmonic capo the notes will sound like harmonics creating a very unique sound coming from your guitar! To get an idea of what this sound like visit Bob’s website for video tutorials. The Harmonic Capo is only recommended for six string acoustic and electric guitars and is available directly from Bob at weaseltrap.com. Credit: Bob Kilgore/weaseltrap.com.
