The SHUBB capo is designed to reduce tuning problems. Its custom material presses the strings just like your finger tip. Its unique design closes onto the neck just like your hand. Its pressure is totally adjustable and easily repeatable. Shubb makes capos for just about any stringed instrument. We carry Schubb capos for 6 and 12 steel string guitars, classical guitars, ukuleles banjos and partial capos.
