I listened some sound of this instrument on youtube;
Very good sustain study I admit! far from rock guitar stupid-filtering ideas.
Result seem also really more better than Fernandes systems and Sustaniac too; even if .. please do not forget Sustaniac old model is the heart of Robert Rich lap steel magnificient sound!
In any case the price above mentioned is simply absurd.
It come in my mind a chat with sir Jeff Pearce some years ago,
when I asking him about his beatiful guitar sound processing ...
he surprised me with his usual irony, saying "Giorgio, yo just need a volume pedal..."
?! I realized afterward he was right!! (of course), and he was serious on his statement!
I think you can realize with a standard guitar with a volume pedal
an half of sounds I listened coming with this toy for millionaires ...
