After using the TT a lot and being a believer in the product, here are a couple features that would be amazing to see in a future app update if possible: 1. A "Full Spectrum" mode that automatically cycles through chromatic major and minor chords for the guitar's full range of notes in all registers. The time duration between chord changes could be a user-selectable option (i.e. 1-10 seconds) or TT could have a preset time between changes. This would expose the guitar to a wide range of shifting frequencies that, in theory, would help a guitar sound and feel "played in" much quicker for those who can't have their hands on a guitar for several hours every day. A "Randomize" button would also be cool for more abrupt frequency shifts. 2. Custom Scale "User Presets." This would allow the user to program unique chords, tunings, or focused frequencies they want to send to the guitar with the push of a single button rather than manually selecting/deselecting notes every time they want to change their note selections. A bonus feature would be a "Play All" button that cycles through the various presets to simulate chord progressions or custom spot training for stubborn instruments. Anyway, just thought I'd put it out there. I'd still be a happy customer if these things aren't possible, but one can wish, right?

Why yes... yes it does. I originally bought the Tone Traveler after getting a '92 Les Paul Standard on Reverb that I almost got rid of. The guitar looked great and had a fantastic neck that pretty much played itself. The downside... it was dead. It was quiet unplugged, the low end was thin, and the guitar barely vibrated. I've got eleven Les Pauls from '86-'02, and while they all have their own unique character and personality, this one was the black sheep of the group... I thought I bought a lemon and realized why the previous owner wanted to sell it. Once I got the Tone Traveler, I alternated putting it between the bridge/tailpiece and the headstock resting on the nut. I used the standard guitar mode as well as the custom scale to get the guitar vibrating as much as possible; periodically touching the neck, headstock, and body to feel how much the guitar was moving. I would switch modes, isolated notes, and major/minor/complex chords every couple hours to vary the frequencies I was feeding the guitar. The results were really amazing! A guitar that felt thin and dead in the hands came to life! Now it has a deep low end, it's more acoustically resonant, and you can really FEEL the neck and body vibrate when playing chords; something that simply wasn't there before. I've done the same process for several of my guitars; some taking longer than others, but currently doing it to a case queen '02 R7 Les Paul I recently got. It's already changing after a couple days and I can't wait to see this guitar come to life as well. All that to say, experiment with all of your guitars. Get the wood vibrating and you'll start feeling the differences in a pretty incredible way.
