The Korg DT-10 is an excellent choice for a stage tuner. It will fit perfectly on a pedalboard or as a stand-alone unit. It's perfect for a gigging musician as it one button controls whether the tuner is on or off and when it's on it totally silences your rig which is great facilty to have on stage. It is powered by either a 9v battery or a power adapter so it's easy to add it to an existing multi-input power brick.
