According to Eric, he used a Vox wah pedal to record the song White Room from Cream’s 1968 album Wheels Of Fire. Based on this, it is also likely that the same pedal was used on earlier stuff, like “Tales Of Brave Ulysses” from Disraeli Gears.
G.P.: What kind of wah-wah pedal do you use, like on the “White Room” track on Wheels Of Fire?
GP Flashback Eric Clapton June 1970
E.C.: Vox.
Eric obviously didn’t specify the exact model, but given the time period, it is likely that he used a V846 model (more about this pedal and the origins of wah-wah can be read here – The History of the Development of the Original Vox Wah Pedal).
I attended Eric Clapton´s concert in Copenhagen yesterday (june 14, 2022) and the pedal used there was clearly marked “cry baby”.
Alright, I’ll check it up, thanks. I haven’t really looked into his most recent gear.
