What is your opinion of this product?
I love this little tuner as it is well built and precise. However, be patient when first using as it can be exasperating. Find the "guitar" and the "sustain" functions(the manual will explain) from the top buttons and have at it.
The tuner frustrated me at first as I wasn't use to tuners as accurate as the Peterson. Once I got used to it, I won't use anything else.
