Be careful if you attach this tuner to an acoustic guitar with a Standley Click-on Guitar Foot stand.
Only once the guitar felt down vertically to the front, on a carpeted floor.
Nothing happened to the guitar, but the screen of the TU-05 got broken, now there is a scratch on the display and it became completely useless.
Boss could fix this problem from happening, if they could just provide a 9H tempered glass screen protector designed for this screen.
Good that Thomann.de provides a fair compensation for this incident, so I am only satisfied with the service, not the product.
