Secure and Reliable

The TU-02’s high-contrast color display provides accurate, easy-to-view tuning everywhere you play. The rugged, padded clip securely grips to your instrument’s headstock, while swivel adjustment lets you position the display for the optimum viewing angle. A single CR2032 lithium battery provides continuous runtime up to 24 hours, and an auto power off feature conserves battery life when the tuner is idle.

Works with Guitar, Bass, Ukulele, and More

With its versatile modes and quick-change design, you can tune a variety of instruments with the TU-02. Choose from standard tuning modes for guitar, 4- and 5-string bass, and ukulele, or chromatic mode for alternate tunings and other stringed instruments. Flat tuning over a range of two semitones down is supported, perfect for players who like to tune low for a heavier sound. And with adjustable calibration from 430 to 450 Hz, you can set the tuner to a reference other than the default 440 Hz standard if needed.

Best guitar shop in Ontario. Tony is an absolute gem and a pleasure to deal with. Tons of selection, knowledgeable staff, clean store and great prices.

Just purchased a Seagull S6 QIT online from Picker's Alley. It was shipped the day I ordered it and I received it the next business day. The guitar was much nicer than I expected, a very high quality product, and it came out of the box absolutely pristine, set up perfectly and even in tune. Great product and service. I couldn't be more satisfied.

What a great store. Brands like fender, Gibson, Yamaha, Godin, charvel, Boucher, and Taylor. Lots of new stuff, and some really nice used stuff too. I found the staff very friendly and knowledgeable.
