My little cousin brother, who has recently been inspired to pick up the guitar, now wants to learn more than just playing the instrument.
I'd say that we are not a musical bunch but when he says he wants to produce different sounds from the guitar, after learning the basics, I thought of the Rocktron xpression Guitar Multi Effects Processor.
I've seen a friend using it in his music studio. If I remember correctly, it has ten different effects and more than a hundred presets for guitar and bass. Perhaps I'd take my cousin there for a visit and see how comfortable he is with the features first.
I don't want to invest money on it and then find that he has lost interest in it. You know how young people are these days.
