Re: Super vs Twin reverb
A more "fair" comparison of Fender BF amps would be the 410 Super Reverb versus the 212 Pro Reverb. Both have the same power, but the SR has the MID control in the VIBRATO channel. The Vibrolux Reverb has slightly less power in a 210 combo. A clean Vibrolux probably commands the highest price in the vintage market.
Then again you have the Band Master rig, with its head and 212 cab, but no reverb...also 2x6L6. Its big brother is the 85-watt Showman head, and little brother...the Tremolux, clocks in at 35-watts with a 210 cab. The Tremolux is one of the best blues club amps I've ever used, and I deeply regret selling mine. And a lot of guys love rocking the bare-bones Bassmans.
Of course back in the mid-'60s and well into the '70s, there wasn't all this emphasis on playing distorted. You wanted loud and clean. Indeed, Fender marketed the Champs, Princetons, and Deluxes as student or practice amps. A bunch of us went to see a friend who was also doing a single act and we gave him a bad time because he was using "only" a Deluxe Reverb. His amp had been stolen, and the DR was all he could afford. He couldn't wait to get a bigger, cleaner amp, and I think he wound up with an Ampeg VT-22. (A BEAST!)
Of the single acts I knew in the '70s, I'd say at least 90% were using minimum 100-watt tube and SS amps...Twins, Ampeg, SUNN, Kustom, Acoustic, Music Man, et.al. And that's what the bands were using too. I remember the guitarist in one of my favorite bands used a Music Man 210HD 130, and thinking how cool it was to have all that clean power in a small package.
There were a few kids in my high school (Class of 1968) who had Fender SRs, and a few who had the top-line Silvertones, too. The SRs, and Fender amps in general, were cream-of-the-crop. I always like their tones, but never bought a Super Reverb. As mentioned before, they are really awkward to carry and difficult to fit in a car. A Twin or Pro also weigh a ton but are easier to manage. And the 10"s in a SR are so much quicker than the 12"s; with certain guitars they can be overly bright. I prefer the 212 models.
After owning and playing various Fender, SUNN, Acoustic, Randall and Marshall amps, I found my dream amps in the Mark III, IV and V Mesas. The original Boogies were based on the BF design. They have the power and the clean tones I need. They sound good at lower volumes. The lower watt settings are perfect for practice and tiny clubs, or terrific crunch tones. With the full power setting and the EVM speakers of the combo and a Thiele cab it will hang with any Marshall stack, and the combo+Theile has a smaller footprint than a Twin Reverb. And a Boogie sings like no other amp. To me, they are the best of all worlds.
But there is no denying the brilliance of the BF Fender amps. Fifty-plus years later they are still filling studios and stages around the world. Hard to argue with success.
