Boss TU02 Chromatic Clip-on Tuner

Boss TU-02 Chromatic Clip-on Tuner is Boss's latest foray into cableless tuning. Despite being listed as a guitar tuner, with four independent modes of operation, this versatile device can bring consonance to a range of string instruments: 'Guitar', 'Bass', 'Ukelele', and 'Chromatic' for others. Perfect for taking on the road allowing you to tune in spots without a power socket, the astonishing 24 hours battery life means you won't be caught short, while the intelligent auto power off feature conserves power when not in use. This is not at the expense of performance however, the high contrast colour display is bright and provides easy visibility for dimly-lit areas such as stages. If you need a reliably robust clip-on tuner, get the ever-dependable TU-02.

Great price, smaller than my old one but big enough to read. Ideal
