A Solution in Search of a Problem

How many of you who own a Twin Reverb have decided that it isnt loud enough? Any of you? Figured there isnt anyone who needs a louder Twin. Ok lets try another question: How many of you think the Twin Reverb isnt heavy enough? Same response? Figures.

Well, CBS decided that there is a market for a louder, heavier Twin.

It hungers for eardrums

At 180 watts, but depending on how it is biased you can get these things to output 250 watts, these things are loud. Because sound pressure levels are logarithmic, not liner its hard to compare the real volumes between a standard Twin and a Super Twin, but simply saying that its "Louder than a Twin" says enough.

As far as features went it had a graphic eq section, a notoriously awful distortion channel, and the infinity loud clean channel. These were made from 1975-1977 or 78. They wern't made long or in mass quanitites because there simply wasnt any demand. Current prices are still low because theres still no demand. The amp circuit was useful for one thing though:

This amp is not useful for the studio at all by the way

Besides the brute of the Fender 400ps, this is probably the most capable tube bass amp Fender ever made. Its identical internally to the Super Twin, minus the reverb, distortion, and a modified EQ.  It was, oddly enough, a combo amp with 1 15 inch speaker. The speaker could in no way handle the wattage, and the amp was extreamly heavy, so most people just cut the cab up to make the amp into a head. This is actually my main amp, and I did just that to it. Even more problematic than just the speaker and the weight was the cabinet's tendancy to fall over because of how top heavy it is. Once in head form, it makes for a mini SVT of sorts, just more Fender voiced because of the sextet of 6L6 tubes it contains.

CBS had sort of an obsession with extreamly loud and heavy combo amps durring the mid 70's. Some other highlights include:

Fender Quad Reverb
Its a Twin Reverb with a 4x12 cab instead of a 2x12 cab. Cleans for days but weighed over 100 pounds.

Fender Super Six Reverb:
135 Watts. 6x10. 140 pounds.

Most of these amps are fairly rare, but also fairly worthless because of their size and weight. Ive seen Quad Reverb amps go for as low at 300 dollars because they simply cant be moved by one person. Most of these amps wernt particularly great guitar amps either. They were clean for days but by the 70's most guitarists wanted good overdrive, which ironically the 50 watt Bassman amps had. Many bands would have the bass on a Twin or a Dual Showman of sorts and the guitar on the Bassman. If they had changed around the nameplates maybe they would have had an idea there. But they didnt, so these amps float around Craigslist endlessly.
