on TOT i used one of my Fender Custom Shop strats i had at the time, the sunburst one, which had an EMG 85 in the bridge and a SRV Texas Special in the neck posiition. the "slidey" melodic harmony line was played with the SRV. the only really consistent thing about my lead tone over the years, other than my hands obviously, is an ibanez tube screamer pedal.
