In his interview with Dan Forte for Guitar Player magazine in 1985, Clapton commented that he was using a pedal board with a bank of presets built for him by an engineer that worked with Steve Lukather, namely, Bob Bradshaw. Lukather met Clapton as a part of the Los Angeles 'A Team' of studio musicians during the recording session there for the tracks to be included in the album Behind the Sun.

Clapton's guitar technician explained to Dan Forte that it was a programmable foot switching system which would allow the user to pick out presets and punch them into the memory. He further commented that the units in the rack at the time consisted of an Ibanez Harmonics/Delay, a DBX 160 compressor, a model SDE-3000 Roland delay, a Dyno-My-Piano Tri Stereo Chorus, that had three choruses in one, a Boss CE-1 chorus, and a Boss Heavy Metal pedal that Clapton heard Lukather using and liked. He added that Clapton used 'a bit of chorus, the CE-1, and a dash of compression'.

This Bradshaw system was in use until 1989 and was coupled variously with The Marshall amps (1985-c.87) in Lot 87, The Dual Showman amps (1988) in Lot 88, the Soldano amps (1988-89) in Lot 91 and the Dean Markley amps (1985-87) in this lot.

During the period from 1984 to 1988, Clapton's amplifiers were usually placed off-stage in a position accessible to his guitar technician and only the Marshall speaker cabinets were visible on stage to the audience. However, on rare occasions when Clapton was guesting at other acts' concerts, the amplifiers were placed on stage and hence visible to the audience. However, the presence of the Bradshaw system was manifest on the ever-present foot-controller on stage. Either of the two foot-controllers in this lot could be spotted on stage at Clapton's foot during his Behind The Sun world tour and The Live Aid appearance (the foot controller and the rack case were both visible on stage) at the JFK Stadium in 1985, various Prince's Trust Rock Galas with George Harrison, Paul McCartney, Ringo Starr and Tina Turner during this period, his Royal Albert Hall residencies which originated in this period, Nelson Mandela Concert at Wembley Stadium with Dire Straits and Clapton's 25th Anniversary tour of Japan with Elton John and Mark Knopfler in 1988.
