    As reviewed by David Catron on 12/6/2010

    I bought a BOSS 12H guitar tuner 12 years ago, it finally gave up the ghost last month & I am replacing it with the newest model of the exact same tuner. It absolutely always gave perfect tuning for electric or acoustic, would even tell you whether your voice was exact pitch; In fact we looked at an electronic keyboard to purchase, I checked it with my tuner & we did not buy it because it wasn't exact pitch. HINT: Buy the AC adapter, tuning is difficult w/ low battery.
