A few months.
- What thing do you like most/least about it?
It's amazing! Nothing else i've ever tried does anything like this!
It's small...easy to carry around...and can even work on an acoustic if you practice a little.
- Did you try many other models before getting this one?
Nope, i heard about it & ordered it!
- What is your opinion about the value for the price?
I paid 60 € i think, but i think it's still expensive for what it is. Should be half that, if even that much...
- Knowing what you know now, would you make the same choice?...
It takes quite a bit of practice and if you're into this sort of thing then maybe check out the Moog Guitar...which might be much better.
But, well, listen to Brian May's work on Queen records and that'll give you an idea of what can be done with this thing. It's unique, and it sounds that way.
