Your general opinion of this product.
This is a well made, rock solid little pedal. It does one thing and it does it really well. it gets you in tune. strum all six strings, it will show you which strings are out of tune (Polyphonic Mode). go to the single out of tune string - pluck it and it switches automatically to single string mode from polyphonic mode.
it runs on a 9V or a power supply (not included). it also allows you to daisy chain a power supply cable to power your other pedals.
and now for the BEST part - this pedal was selling for $99 just a few weeks ago... right now you can get it for $69 - such a deal!!
Buy it, you won't regret it.
