Joining the Experience for the initial “Watchtower” session was Traffic guitarist Dave Mason, who, it was decided, would contribute a 12-string acoustic part.
“Dave hung out a lot with Jimi and was a regular in the studio,” says engineer Eddie Kramer. “Jimi was aware of his ability and felt that he could cover the part adequately.”
Jimi, says Kramer, had a firm understanding of just how the song was to be arranged and performed, but the session proved to be anything but smooth. Mason, whose job it was to double Jimi’s six-string acoustic rhythm part, struggled mightily, causing Jimi to reprimand him several times.
Hendrix and Noel Redding also clashed, and the bassist, angered by what he saw as Jimi’s obsessive quest for perfection, bolted from the studio midway through the session. Mason took over the bass in Redding’s absence, but Hendrix ultimately overdubbed the part himself, using a small, custom bass guitar that Bill Wyman had given to Andy Johns.
After the basic rhythm tracks were finally completed to Jimi’s satisfaction, he turned his attention to the song’s four distinct solo sections, each of which were recorded separately. “Once Jimi started working on his solos, the session moved very quickly,” says Kramer.
“The thing that occurs to me was how completely prepared he was. One thing that people don’t realize is that Jimi always did his homework. He and producer Chas Chandler always got together to work out ideas well before he walked into the studio. Jimi knew exactly what he wanted to play.
“He used an different tone setting for each part. I recall him using a cigarette lighter to play the slide section, and that the delay effect on each of the sections was applied later. I used an EMT plate reverb—that was the only thing available to us at the time.”
