Ease of Use: 

True bypass. Active DI can be used to send your instrument's signal to another amp - and it has ground lift to eliminate hum caused by ground loops. What other pedal tuners can match these features? I can't think of any others that are true bypass and have active DI with ground lift.  


Programmable to your own tempered tuning. You can adjust the base pitch in increments of 1 cent. This is handy if you are playing with, say, a piano that has been tuned slightly off concert pitch. Basically you can "tune the tuner" to whatever pitch you require. 

Incredibly accurate, stable and very fast. LED display is bright enough to be visible in almost any lighting situation, including outdoors during daylight.

Compared to the Boss TU-2 Tuner that almost everybody seems to use, the Peterson is streets ahead in every respect. I used the Boss for several years and found it very innacurate. It would "drift" noticeably, and it wouldn't track strings consistently. No such problems with the Peterson.  


The tempered presets are of questionable value for most users. I mean, how many of us will find a use for all those Buzz Feiten presets? I've only tried the GTR "sweetened" tuning, and found that it actually makes the A, D and G strings out of tune in relation to each other - exactly what you don't want when playing powerchords through a hot amp. The menus and options can appear a little daunting at first, but once you scroll through everything it becomes quite intuitive and logical.

Customer Support: 

No idea! Never had to contact them.


I bought mine used, and it's always worked flawlessly. It's very ruggedly built, and with normal use I can't conceive of any problems occuring. The large LED screen is the only part that could easily suffer damage, but it is somewhat protected by the design of the box. If you check out the photo you'll see that the screen is countersunk into the pedal, with metal humps on either side to help deflect anything from impacting the screen.
