At first I was a little skeptical about shopping in this web store, but I decided to give it a try and ordered this guitar tuner. I was very impressed with the time that passed from the moment of ordering to the day of delivery. Superbly done - only 3 days. Thanks Muziker for the express shipment. The D'addario tuner itself is of high quality and precise. It surprised me with its sensitivity to vibrations over the wood of the guitar it attaches to. Another advantage of this tuner is that the screen can rotate 360 ​​degrees, so it can be easily adjusted to any instrument and adjusted so that it is visible in front of your eyes. The screen is perfectly visible in daylight and the colors are vivid with plenty of contrast. Basically, I highly recommend this tuner to everyone! Well done Muziker!
