Usually, when I see a guitarist constantly pissing about with the tone controls, the volume controls, the pickup selector switch, the tremelo vibrato bar.... I'll be (internally) shouting "leave it the fuck alone!". But not with Jeff Beck. He was never "pissing about" with them. Everything was considering and crafted into a unique tone. If ever the saying "It's all in the fingers" applied to anyone, it was Jeff.
Also, most of his peers got good in the 60s and then never changed. He completely changed his style over time and was still making great music...
RIP.
