Boss TU-80 Tuner & Metronome

My lead guitarist has one of these tuners. His is 20 yrs old and he still uses it flawlessly. That's all the testimonial I needed. I got this and am thoroughly satisfied. I detune my Martin two steps and this tuner let me tune the guitar right on the money. Terrific item. Highly recommend it.

I heard that it was a great product so I bought one for a great price

As it turns out - even though I heard great things about this product, when I got it, I was surprised at how small the items on the screen were. Way too small for an old man like me to read. I'm going to give it a great review because it's not its fault that my eyesight is so poor. I hear that it's a great product. (Instead I use a Snark - which I can read easily.)
