Gearank Recommendation

The Pitchblack Pedal appeared on our recommended list for Pedal Tuners from March 2017 until April 2018.


The Pitchblack Pedal is designed for use with both guitar and bass and includes a 9V out for providing power to other pedals.

It also has true bypass so you don’t need to worry about it eating up your tone when you’re not tuning.

Some guitarists choose this over the Boss TU-3 because it’s more compact and takes up less space on your pedalboard.

It’s used by both electric and acoustic-electric players.

One thing to note is that you have to unplug your guitar cable from the pedal to ensure it stops draining the battery. Of course, this isn’t an issue if you’re using a power adapter.

When compared to the Boss TU-3 the Korg Pitchblack Pedal is a little cheaper and is also appreciated by musicians who sometimes have trouble seeing readings under some stage and outdoor lighting conditions.
