Thrilled, Set this up with a microphone in the center of my Jam Room, This will now allow me to get rid of the three Boss tuners that were just enough off from one another that I could never confidently tune multiple guitars on different tuners. And, the first thing I noticed was when playing the chord progression right before the lead in Still of the Night was that the chords sounded so much more like they were supposed to. I feel like I am actually in proper tune now. I've always wanted a strobe tuner since I saw Angus use the one in the Let There Be Rock video, almost 37 years ago, and now I feel like a dumb-azz for having waited so long. If you have ever thought you wanted one get it, far superior to the pedal you likely to be using right now.
