All I can tell you is that you've got to check this thing out. If you type in INTELLITOUCH in the search window on Wholenotes home page, it'll get you to the website.

Where Obtained: Guitar Center
Just clip it on the headstock. Works equally well on electrics or acoustics. This thing just amazes me. Ambient noise (crowd noises, other instruments and such) will have absolutely no affect on the tuners ability to sense the vibrations from your instrument. Way Cool.
I was a little skeptical at first, when the salesman showed it to me. I initially thought I was going to buy a Korg, but since Guitar Center has a 30 day, no reason, bring it back for refund, policy, I thought what the heck, I'll give it a shot. I Wont be bringing it back!
Find one, check it out, and I'm sure that if your in the market for a reasonably priced tuner, you'll snatch one up too. BTW..I understand theres also a PT2 thats less expensive, I'm not sure what the difference is, but my guess is that its not programable like the PT1, the PT2 lists at $40, so you can probably pick one up for about $30.
Construction is comparable to traditional electronic tuners, although smaller. Its a new concept, so the company dosnt have a track record yet, but hey, I tell you what, there on to something here big time. Its a typical plastic case with a nice red backlit LCD display.
Durability wise, I rate it a 4 because, hey what the heck it is plastic.
