I recently saw a reference to this device here but can't locate the thread and a search did not produce anything. I googled it and found the site where it is sold (@ $20 US). I'd appreciate some input from those of you who are familiar with this device. Is it helpful, how can it best be used, etc. Is it worth buying? I should say that I'm currently working specifically on intonation and tone improvement. I have an electronic tuner but would like to improve my "ear."
