The Boss TU-15 Chromatic Tuner gives guitarists the most accurate tuning possible -- bolstered by new Accu-Pitch and Octave Adjust functions -- plus popular Drop D, open and flat tunings. A back-lit needle and LCD make tuning easy, while improved high-impedance inputs let you connect between an amp and guitar without signal loss.
Quality: Plastic casing won't hold up as good as metal that's for sure.
Value: Way too pricy for the matirial Boss used for this product
Desirability: Its accurate at its best, forget about all other matrix dot type of digital tuners.
Sound: Never put a tuner in the chain
Overall: The price on this tuner is just way too high, for this price I expect metal casing and have input and output jacks mounted on the casing not on PCB board which would break easily, well how about at least include a little carrying bag for protection? the answer is no. this product is made in China and the labor there is cheap you know?...
