An additional change occurred in 1970 with the addition of a capacitor to eliminate “ticking” in the tremolo circuit.The next change was the addition of a master volume control in 1972. Now, having a master volume control on a Fender Twin Reverb, or most any other Fender amp of this era, seems like a useless addition.As you can imagine, a signal derived from this circuit could have substantial level, which could easily overdrive a preamp tube—and since the overdrive comes from a little tube power amp, it should sound pretty good. I’ve never ascertained if this is because the reverb drive signal simply doesn’t sound as good as you’d expect, or because of where this signal is applied in the amp.Either way, this under-whelming overdrive tone—together with the master volume and other post-1967 circuit changes—is why your amp is, in your words, maligned.In 1968 Fender changed to the “silverface” control panel.
The amps Fender produced between 19 are known as “blackfaces” because of their black control panels, and their designs remained largely unchanged during this period.
I just got a ’70s silverface Fender Twin Reverb that needs a little TLC.
Surfing the various forums, I’ve learned that this master-volume edition of the Twin is one of the most (unfairly, to me) maligned designs.
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.
