The snark air rechargeable clip on tuner is designed for players who want quick fuss free tuning at home in rehearsals or on stage. With no buttons or switches everything is handled through simple touch control so you can tune one handed and stay focused on playing. This makes it especially useful when you need to make fast adjustments between songs. The 360 degree rotating display helps keep the screen clear wherever you choose to clip it. You can place it on the front of the headstock or keep it hidden behind then tap to change the display orientation so it stays easy to read. This flexibility works well in different lighting conditions and playing positions. Usb recharging means there are no batteries to replace. A single charge lasts weeks to months with regular use and the accurate tuning software supports electric acoustic and bass guitars along with ukuleles banjos and more.
