Dating silverface twin reverb

I just got a ’70s silverface Fender Twin Reverb that needs a little TLC.

Master volumes are generally associated with and necessary in amps that use considerable front-end gain to overdrive the preamp section.

The signal level can then be reduced prior to the output stage to control overall amp volume.

Fender switched back to the blackface era cosmetics some time in 1980.

Twin Reverbs produced between late 19 have a black control panel and silver sparkle grille cloth.

But don’t lose sleep over this, as most post-blackface “improvements” can be returned to pre-’68 specs, yielding a pretty toneful amp. I hope that sheds a little light on your amp, but remember: It’s only a bad amp if you don’t like it!

Jeff Bober is one of the godfathers of the low-wattage amp revolution.

In 1968 Fender changed to the “silverface” control panel.

The circuitry was altered as well: There were changes to the bias and phase inverter circuits and, most important, the output stage.

Thanks, John Gilbert Matt Alcott Hi John, The Twin Reverb design has been through many iterations since its 1963 debut.
