Cavallo, who had studied techniques used both by Jimi Hendrix and Jimmy Page, used a three way input from the acoustic guitar (direct, via VOX and Amp), and got Rzeznik to play with a Fender light pick closer to the bridge, a classical music technique known as "sul ponticello". In mixing with the recording engineer, Cavallo then created a curve-mix on the guitars spectrum, turning down all the mid range whilst adding both brighter high and more bass. The majority of the electric guitar parts were played on Cavallo's "glass-guitar" (a technique he would use on many of his later recordings), a hard-tail Fender Stratocaster with a bridge mini-humbucker pickup fed directly to a 100W head unit.
