Carlos Santana‘s sound is affected by the gear he uses, including his Mesa Boogie Amp (and others), Mu-Tron Wah Wah Pedal, and of course his recognizable Paul Reed Smith Santana Guitars. His history with Paul Reed Smith, especially, is fascinating: a symbiotic relationship that has enhanced both men, while producing a fine series of guitars, including the:
PRS Santana I Guitar
PRS Santana II Guitar
PRS Santana III Guitar
PRS Santana SE Guitar
PRS Santana SE II Guitar
and the latest in the series, the PRS Santana MD Guitar.
