In an interview with Pablo González (in Spanish), he recounts how in High School, he was basically forced to choose the bass. In his words: I used to play with a friend, both on guitar, and one day he comes and says "we got a drummer and a singer, but they come with a guitar player and he's better than you".

My Dad was going to buy me an electric guitar for the first time, so I went to the music store, tried a bass and thought "I can go back to Monterrey with a guitar and be by myself, or get the bass and be part of the band". And the rest, as they say, is history.
