Tuner cheap, convenient visibly strong.
The power supply adapter is not provided, it is indispensable for this creature eats the batteries in no time (as long as the input jack is connected, it debits). Response time too long for my taste, but for that price it's worth it.

If I were rich, I would have something else (and if I were rich I would take a robot guitar from squarely in Gibson, so he no longer even need to pay).

To agree on stage without having to unplug the cord and beast without breaking the bank, the tuner is ideal.
