The fetish for old guitars isn't reflected in most musicians choice of computers. All the bands I see have a brand spanking new Macbook on stage with them, even if the guitarist is struggling with a 70s vintage Fender. Even guitarists are finally leaving the dark ages in some respects, with the Kemper modelling amplifiers becoming the standard for touring bands. Now us bassists, well we're still wedded to our hernia inducing valve or solid state amps since the lightweight class D stuff can't reproduce low frequencies very well.
