U2 in Vancouver

"I tend to do something with the guitar sound, use certain effects fo fatten it, rather than just use it clean - though on 'War', it's cleaner than the previous two albums. I use the echo in a very concise way - I try to use the repeats in time with the music. Most guitar players would use the full spectrum of the guitar to get across the power and dynamics, but by using the echo I can get away without using the bottom strings so much. I tend to use three-, maybe four-note chords rather than the full six and to use the top strings, the top end, which gives that distance between the bass and the guitar, and gives me a bit more freedom." - Edge on War, 1983
