The PowerTune system is just completely off the hook wild crazy amazing. It tunes your guitar in 2 seconds! You just STRUM the 6 strings then it automatically tunes your guitar. I WANT ONE! Or two, or...
Check out this PowerTune video here.
The parts to the PowerTuner are here: 1) The tuning knob, 2) The tunecontrol-bridge, and 3) The powerhead locking tuners.
You can even change tunings in the middle of a song - it's that fast!
Let's hear it for German engineering!
Cheers,
