Según lo que dice el fabricante en la entrevista del enlace que ha puesto TheSpiderJam, los primeros que hicieron costaban $30 para promocionar el producto, pero lo van a poner a la venta bastante más caro:
Why is it so inexpensive? These types of guitar accessories usually cost a fortune.
Good question. And it's going to cost more going forward, but these are being sold as commercial samples to get guitar players worldwide working with the product. The goal is to have a number of current generation of guitarists become proficient with the device and that as their careers grow, awareness of the product will grow with them. Similar to the way the Floyd Rose whammy bar became a staple for guitarists because of Eddie Van Halen.
