[processing the rhythm strums] That was real tape phasing. This was in the days when you took the tape off the synch head, put it though a couple of other tape delays, and then brought it back with the play head. There is no processing whatsover on the solo in that tune, as far as I remember. I used John Deacons's small amplifier and the Vox AC-30 to do those little three-part chorus thing behind, as well as the fingerboard pickup on the guitar. There is a bit more tape phasing on the end of that track.
