David Glimour is a genius... and he used effects better than almost anyone beside maybe Jimi Hendrix... A modern day version of him would be Tom Morello...... But anyway... "Time" is a pretty wierd song because each verse is slightly different... He changes his styles slightly... Most of his "tone" comes straight from his fingers though... practice those bends and play with some light strings.... He also uses EMG pickups in his strat... which contributes to his tone quite a bit.
