Korg GACS Guitar Tuner Review

Korg GACS First Impressions


This tuner worked as good as any at a lower price than many I have seen and used. First, let me state that I am not a piano tuner. I gave it to a child for her birthday who was going to become my new student. The switch output goes directly to the Korg, and it's output to a delay and DI box. However, it's very convenient when practicing or playing casually.

Korg GACS Final Thoughts

"Beats every other I've owned."

It just might be more 'functional' than I actually need. Basically everything you want and expect out of a tuning pedal at an amazing price. Korg also has the instruction manual as a PDF online if you need it. I've used this in all my practices and shows for 2 1/2 years and it's awesome! Great used pedal, these things are workhorses.
