EX PT-21 Guitar Tuner Review

EX PT-21 First Impressions

"Tight and hold tune well."

These are typical of EX quality but, the first ones I've owned of this style. Only annoyance is that in selecting keys they are flats. It worked fine, and the price was certainly right. To get around to the pitch, it is there NOW. When I saw the EX my curiosity was piqued.

EX PT-21 Final Thoughts

"Fits great with my tuner."

I've bought two other similar tuners before, none of them worked well. I play in tunings such as E flat standard, Drop D all the way to Drop A. Decent tuner, but the tuner on my Line 6 M5 is more accurate. They lock well, look great and adjustments are great with the 19:1 turning ratio. Not a big deal, unless you want to compare to other pedals.
