The venerable Guitar Player has posted a list of “The 10 Most Iconic Guitar Amps.” You could probably run down the roster yourself: Fender Twin Reverb, Vox AC 30, Fender Bassman et al.

Introduced in 1965, the amplifier included four inputs, two channels, 100 watts of searing power and a Plexiglas faceplate (hence “Plexi”).
