MXR M400 Turbo Tuner

Being able to tune quickly and accurately is important for every guitarist. Whether you’re playing in your bedroom at home or selling out the Ziggo Dome every year, a reliable tuner is always a good investment. The MXR Turbo Tuner delivers just that.

With a large, easy-to-read LED screen, you can clearly see what you’re doing even in the darkest places, and the 0.02 cent accuracy ensures you’re always perfectly in tune with the rest of the band. In addition, the MXR Turbo Tuner offers some extra features such as: adjustable range from 300.0 to 599.9, a USB connection for firmware updates, true or buffered bypass, and a 9V loop-through, so you don’t have to sacrifice a 9-volt output from your power supply.
