This capo is reversible, and does the job of 3 other partial capos. It is the lightest weight, easiest to reach over, most versatile, least noticeable and most attractive partial capo. It does 80% of all things that matter in the world of partial capos, and fits more kinds of guitars than any other type of partial capo. It is also the key to the amazing new Liberty Guitar Method that uses Harvey Reid's discovery of "Liberty Tuning." Use this powerful tool to get started playing guitar, and use it the rest of your musical life. It can clamp 3 or 4 inner strings on most guitars, and on most fingerboards it can also clamp 4 outer strings. It does everything an Esus 3-string capo can do, plus a lot more, since it can be moved very high up the neck, and will work on wider-neck instruments and those with higher string action. On most guitars, it can clamp XXXX00, 0XXX00, 00XXX0, 0XXXX0, and 00XXXX. Common 3-string capos don't have enough "reach" and string clearance for some special partial capo situations. The threaded mechanism allows you to get the perfect amount of clamping pressure without pulling sideways or overtightening. It attaches from either side of the fingerboard, for access to strings on one side or the other, or for better stability. • Strong, ultra-lightweight, will never wear out. • Perfect for both versions of the exciting new Liberty Tuning • Will also do about 2/3 of all the most useful partial capo configurations • Low profile is easy to reach over and around • Attractive and barely noticeable on the guitar • Works as a full or partial capo for mandolins, octave mandolins, mandolas, electric bass, ukuleles and banjos. If you have never bought a partial capo before, this is the first one you should get, and if you are a partial capo user already, you'll want to immediately add it to your collection.
