Wow I like this! I've got a couple SX strats that could use this. I love the speed and accuracy of the the motors.
Let me say that i play guitar with a lot of alternate and open tunings. And am acutely aware of the herd of various tuning guitars problem. So I've been working to solve it for some time. I have so far spend money on two usable solutions.
One is the Hipshot mechanical tuning mechanism. It fits where the tailpiece goes (like say on a resonator guitar where mine is) and give you three notes per string. That allows it to cover nearly all popular alternate or open tunings (but not all!) with one setup. It's shortcoming is that there is a certain amount of string histeresis even with a Graphtech lubed nut that makes tunings just a tad "iffy". Still I use mine quite a bit. It's not horrible and being mechanical has no battery hassle.
The other thing I've got is two Gibson Robot tune guitars. These are pretty much equivalent to the tronical tune in design only bigger older and clunkier and a previous generation. The tronical tunes much faster and comes into lock much better than my Gibson. But other wise they operate about the same. Also I had the fancy control knob fall apart on my Les Paul and I had to glue it back together (it's a complicated technical mess inside!). And the battery charger is quite flakey and hard to keep working right. So far I've nursed it along, but Gibson customer service is like nightmare city. I asked about replacement batteries and they won't sell them. They won't tell you what they are. They insist you actually SHIP the whole guitar to them for expensive repairs just to change the battery. I can see this is going to be a problem down the road.
Tronical tune has a slide out battery (though they haven't said if they sell batteries yet) and it obviously is special and must be purchased from them, but at least there is some provision for it.
Still the Gibson robot tune system DOES tune the guitar fast enogh that you can have ONE guitar and play various tunings from song to song. I am having serious GAS for a Tronical tuner for a strat.
My only hope is that by the time the battery dies in my Gibson Les Paul, Troncal tuners will have a Les Paul model and I can tell Gibson repair to pound salt.
I really don't see any utility for this kind of device for bass though. But then I never play drop-tuning on a bass.
Yes, I want them to take my money too!
