SE-PTN is specially designed for Stage. This has No Sound Loss by True-Bypass, and when tuning, this blocks the noise perfectly with Low-Impedance Mute output. Guitarist can read the display very easily with Big Size Dot-Matrix. The note flows Left and Right, so it is very easy to recognize tuning. There is no battery loss when bypass.

I have used Artec products before, always of serviceable quality. The big advantage of this tuner is its huge digital matrix - easily seen even in sunlight ( I live and gig in Spain). Solidly built and with true battery bypass. It isn't chromatic, so I can't use it for all instruments or dropped tunings, but overall well worth the money.
