No master. The controls, from left to right:
Vol, Treb, Bass ---Vol, Treb, Mid, Bass, Reverb, Speed, Intensity.
On the back panel you can see the two RCA sockets for the foot pedal for the reverb and tremolo.
This is one of the very early silver faces because it has the alloy trim around the speaker grill. Very nice amp.
[EDIT]:I just about had a heart attack then. I went to look for the Fender Amp Field Guide to link to for this post, and it
wasn't there!!. Eeek!! Found a mirror, though:
