Clapton used both the Les Paul and the SG to create his self-described "woman tone".[148] He explained in a 1967 interview, "I am playing more smoothly now. I’m developing what I call my 'woman tone.' It's a sweet sound, something like the solo on 'I Feel Free'."[148] Writer Michael Dregni describes it as "thick yet piercing, overdriven yet smooth, distorted yet creamy".[149] The tone is achieved by a combination of tone control settings on the guitars and Clapton's Marshall JTM45 amplifier.[150] Vintage Guitar magazine identifies "the opening riff and solo of 'Sunshine of Your Love' are arguably the best illustrations of full-blown woman tone".[148] Clapton's "Fool" acquired its name from its distinctive psychedelic paint job, created by the visual art collective also known as the Fool (just before Cream's first US appearance in 1967, Clapton's SG, Bruce's Fender VI, and Baker's drum head were all repainted in psychedelic designs).
