For your Fender late 60's Amp, here is an original knob.
Notice this has the set screw on the side that sets at #1. Knob shows original wear and tear but functions perfectly.
The other feature is they have the metal insert on bottom of knob.
It shows dirt and wear from being 50 years old. Great to restore your
Vintage Fender Deluxe Reverb, Princeton, Twin, Champ and other Fender Amps.
