This pedal is simple. It helps you tune your instrument and does that well.
It has many cool features like the additional power supply output, true bypass and buffered, and more.
I'm having two issues with it:
The switch
It's very low quality and easy to press down.
Since i have large shoes, sometimes I press the nearby area and accidentally engage the pedal which then becomes a fancy mute switch.
This is an expensive pedal (if you look at it as just a tuner pedal) with a cheap switch and I don't think it would be a much larger production cost if they just put a quality switch.
Polytuning
It's innovative and I'm amazed how people can do something like this.
That being said, I don't think it's there yet.
Sometimes when i try to play single notes when in a loud environment (rehearsal/gig) it registers as if I want to tune all the strings at the same time.
This makes the process a bit difficult and time consuming in some areas.
For me the perfect fix would be if there was a way to disengage the Polytune functionality all together and make it an exclusively single note tuner. Though I see why that might make no sense since it's the whole shtick of the pedal.
All in all, I probably wouldn't buy the pedal again nor recommend it.
It's a bit pricey for (in my opinion) an imperfect product.
I doubt I will go out of my way to sell it, but the idea of exchanging it for a Boss tuner isn't off the table.
