Nice collection of tuners, the first one looks ace!
I've had a Peterson Strobo which was a great tuner, I found it very accurate and quick to use but I got rid of it due to the bigger footprint (although it wasn't massive I wanted a more compact pedal) and the noisy switch which used to pop every time I switched it on and off. I also have a Peterson VSII which I use at home... awesome desk top tuner for setting your guitars up. I have since gotten a Polytune and a Sonic Research Turbo Tuner and they are both great pedals. The Polytune tracks fast enough, has a few different modes including a strobe type display that works great. The Poly mode works well enough with fixed bridge guitars but not with my trem bridges. It also has a power out to feed other pedals. The TT has a really bright display which is good for all lighting conditions and tracks faster than the Polytune but not that much that it would affect tuning in a gig situation, with the true strobe it is good for set ups up too. It doesn't have a power out. Both great compact tuners for sure and now the Poly mini is out there's plenty of great tuners to chose from.
