Slash plays Marshall (he was the first guitarist ever to have a Marshall signature model !) , don't remember the model name ... Never mind anyway , it was limited and almost impossible to find one these days.
His pickups are Duncan "Alinco II pro" , and his LPs are mostly standard or classic models.
He also uses a Marshall distortion pedal , and Cry Baby (rack?) wah , a Boss equalizer pedal & Monster cables.
