Quiet and accurate
Has a small footprint that's perfect for my small pedal board. Switching on and off is quiet - no pops or drops of any kind. True bypass is accurate: when the tuner's switched off, you really can't tell that it's in the signal path.
Display is very bright. I've not used it outdoors but the room in which I use it is at times sun-drenched and, even during those times, I've had no issue seeing the display with perfect clarity. I use the standard display mode (as shown in the stock photo). As with the other pedals on my board, I use a Truetone 1spot cable to provide power to the tuner.
Bottom line: this tuner does the job very nicely, quietly, and (so far) reliably.
