The Korg DT-10BR is an excellent choice for a stage tuner. It will fit perfectly on a pedalboard or as a stand-alone unit and it's very well built with an all metal chassis. 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 9v power adapter so it's easy to add it to an existing multi-input power brick. This one is complete with its original box and operating instructions and I have left the velcro on the base in case you want to mount it to a pedalboard as I did.
