Jeff Beck, in my top five still alive, along with:
Joe Satriani, Eric Johnson and Eric Clapnor (sic).
Definitely there are virtuoso guitarists (Steve Vai for example), but Jeff Beck is the top.
Something I admire about both of them is that they are complete nuts for American hot rods.
Jeff Beck collects them and is a genuine motor head who builds and maintains his own machines -
Clapton has an affinity for tooling around in custom built Ford Victorias that he personally designs and styles in collaboration with Roy Brizio of San Francisco.
Clapton is less likely to be found with grease under his nails but his vision for creation can be seen in this 33 Ford Vicky 4 door. A model that never really existed - notice the wiper position. This car was built with right hand drive to be used in England.
(Of course money helps, too)
