If your pedalboard has little space left, and a tuner is a must, then look no further.
I use this on a smallest pedalboard size and voila I suddenly found another space for a standard sized pedal - with a bigger tuner I did not have enough room.
Don't let the size fool you, it's a great tuner, that responds fast and is very accurate.
After a few days using the tuner, I noticed the pedal introduces noise (I guess you can call it digital whining), possibly from power supply, but after some experimentation, the noise disappears from signal when you turn buffer off - or turn on a pedal after it that does better job with DC coupling.
For some reason the switch feels very different from others I have tried - it's better. I'm sure that's the same switch but I like the feel a lot better than I did on older Flashback delays and newer Flashback II Mini delay.
Best thing is it's on the affordable range, not too crazy expensive but the best for the money
