Mr Daniel Page14th Nov 2023

Quality, reliable pedal. My first tuner was a TU2 and I never had any problems. I know some people can get really picky about tuners, but for me, there is nothing I would change about this. It is super reliable and just works - no clicking or popping sounds. Solid tuner option. The buffer does alter the sound a very small amount - if you use IEMs and you're used to listening at a professional level - you may notice a difference - but otherwise, nothing to be concerned about.

Responsive and simple. Really needed for a professional sound in the studio and at gigs. The power to kill your signal is essential.

Its high quality, durable and exactly what you need from a tuner. I think its a must have pedal, but the difference between tuners is slight.

Solid, classic, dependable tuner, also handy as kill switch to cut off sound when changing guitars or leads.
