Strobe effect is not my cup of tea. Not a true strobe in my opinion.
Simple, easy to use. Runs off a 9v battery or wall wart, but also has a 9v output so you can run another pedal off it. With the battery in, it will save any calibration you made and your preferred display mode.
Has a tuning range of E0 (20.60 Hz) to C8 (4,186 Hz) for you alternate tuning folks.
Can be calibrated from about A435 to A445. Mine was perfect out of the box. I read a review somewhere that the switch was 'flimsy', but I didn't find it to be. It is the same switch as is in my Tube Screamer. It has a metal housing, so the whole thing seems like it's going to last.
It's accurate to +/- 0.1%, and I found it real easy to dial in to accuracy. The LED's fade in and out rather then blink off, so you can really see when you are slightly off center pitch. Just a tiny tweak off with my tuning key and the appropriate LED would just begin to glow. It felt/appeared like an organic response to my adjustments.
It's a tuner. Does it's job and doesn't screw around about doing it. I would highly recommend it, and if it was stolen, I would certainly buy another.
...so ever since then, I always hang on to the buckle.
