60's Fender Deluxe Amp

in the beginning of this video it looks like Van's 335 is plugged into this amplifier

Krantz used this amp during the "Two Drink Minimum" and "Greenwich Mean" era. According to the GP interview posted above: "The beginning of my sound was in 1993, when I got rid of a bunch of amps and just plugged a Strat directly into a Fender Deluxe turned all the way up. That sounded terrible for a year or so, but the good thing is that I had to figure out how to make such a thin tone sound good just by using my hands rather than relying on an amp."

At 10:13min it can be seen that Goldsmith choice is a Blackface era Fender Deluxe Amp.

You can see his amp in this picture he posted.
