FDP Forum / Fender Amps: Vintage (before 1985) / 1966 Super Reverb Standby Switch



Mar 11th, 2018 09:29 PM   Edit   Profile  

The back of my SR has toggle switches for power and standby...

If BOTH switches are UP...should the amp be on Standby (guitar is NOT heard) or off Standby (guitar is heard)?

With both switches up, you should have sound.
If that's not the case, perhaps your standby switch is upside down.
Does the pilot light come on when you turn the power switch to the "on" position?

Yes there is sound with both switches up...I was curious as to why the word "Standby" is on top of the switch rather than below it, making it seem the amp is in Standby mode when the toggle is up..

It all works properly.

Many thanks for the confirmation.

Yep. Ya might think that "Standby" means that when the bat of the toggle is leaning toward the label, then the amp's in Stand By mode ...

Fender should have silk-screened these back plates with STANDBY on the bottom and PLAY on top. But there may have not been enough room below the switch. If you notice, the Carling SPST switch centers for both Power and Standby are located well below the horizontal center of the back plate. This to make enough room for the switch terminals facing upward for assembly.

I might not be correct about this, but I believe tweed chassis were silk-screened the same way. I only have repro tweed chassis around so I couldn't be certain. But I believe that the last time I worked on a real Tweed Super, same thing.

It's a funny Fender quirk. "Standby On" would have been a better choice. I agree about the placement of the switches in the chassis. The switch terminals are offset to the top of the chassis moving the mounting hole downward.

Honestly I never look at the back of my amp when setting up for a gig. I plug it in, feel for the power switch and light it off. The rest of the rig gets set up then I flip up the SB switch to test. Same process since 1974 when I bought a BF Bandmaster.

Vox amps have weird power/standby labels on some amps too.

It's just indicating what switch it is, not what position it is.
