Double Verb: based on Fender Twin Reverb
I haven’t done proper market research but the Twin Reverb may be Fender’s most famous / popular amp, up to this day. It’s big, it’s loud, it takes pedals well. And it’s ultra clean. To get this amp into overdrive requires a volume level that hardly anyone can handle. Unless you’re got your hands on a modded one. Also, the Twin can handle humbuckers well, which is not the case with some other Fender amps.
The NRM and VIB models are based on a ’66 blackface 85 watts Twin Reverb, with the common AB763 circuit (just like the Band-Commander and Deluxe Reverb models). Blackface Twins were produced between ’63 and ’67. This particular amp was modded by Andy Fuchs of Fuchs Audio and breaks up earlier than stock Twins. Cliff:
The SF model is based on a different Twin Reverb, the Vibrato channel of a 100 watts ’71 silverface (circuit unknown, no Master Volume). When I select a Twin Reverb model, I usually choose the Silverface.
Twin Reverbs use 6L6 power tubes. More Twin Reverb information.
Fenderguru.com:
The Twin Reverb has two channels: Normal and Vibrato. Both channels have Volume, Bass, Middle and Treble controls and a Bright switch. The Vibrato channel has additional vibrato and reverb controls. Because of its Reverb circuit the Vibrato channel breaks up earlier than the Normal channel.
Each of the channels has two inputs. Fractal Audio models are always based on the input with the highest input level. To get the equivalent of using the lower input, set Input Trim to 0.500.
The Twin Reverb can be a –painfully- bright amp and model. I always turn off the Bright switch, and increase Treble slightly to compensate.
It also can generate a lot of bass, so don’t hesitate to turn that down a lot.
The Twin Reverb is usually equipped with two Jensen C12 speakers, JBM 120s and even EV-12Ls. I usually use stock cab 21 but there are more Twin Reverb IRs among the stock cabs.
The Twin has always sounded great, also in the first generation Axe-Fx. Here’s @Jens playing the “first gen” Twin model at Dutch Axe-Fest 2013:

The 5F8 TWEED model is also a Twin (no reverb), but with a totally different vibe.

"The Twin Reverb that the model is based on breaks up like that. The model is MIMIC'd and is extremely accurate. It's a Blackface Twin which breaks up easy compared to later Twins. Furthermore, as with all models, it is modeled on the "Hi" input. If you don't want it to break up as easy turn Input Trim to 0.5 to simulate using the "Low" input, reduce Input Drive and MV as necessary. You may want to turn the Bright Switch off as well. People who want squeaky clean usually turn the Bright Switch off on these amps. However, you'd be surprised that a Twin isn't nearly as clean as you think. It's just so damn loud that you get the sensation that it's clean because a light touch on the strings creates a lot of volume."

"If an alien came to earth and wanted to hear an American guitar sound, I’d play him my Twin with a set of Jensens. This was stated by a happy Twin Reverb owner on Harmonycentral.com. It could have been our own words. The Twin Reverb is the king of Fender blackface amps. Having two pairs of 6L6, the popular and traditional two-channel AB763 circuit design, a diode rectifier and enormous transformers (power & output), it offers tons of clean headroom and volume for unmiked gigs and really big stages. Where the other Fender amps break up at around 4 on the volume knob, the Twin stays clean up to almost 6 and will hold up against heavy drummers and bass players with clean notes sharp as a knife edge. This is exactly what the amp is made for, being played unmiked in in a gospel band in a 300-seat church every Sunday. It is designed not break up like the other Fender amps. You need to have your expectations set correctly to be able to appreciate the evil Twin. Warming nr 1) The big transformers and speakers makes this amp weigh around 40kgs, a burden too big for many gigging players who cannot (yet) afford a crew of roadies. Warning nr 2) Volume and clean headroom. If you want tube amp breakup and smoking tones with no pedals you will experience many fights with your band mates and club owners. Just as the other Fender amps the Twin needs to operate in its sweet spot up to sound sweet. After carrying a Twin Reverb on to the stage, the least you should deserve is to crank the bastard. Sadly, we are seldom offered the opportunity to turn the volume above 3 on a Twin Reverb. Instead we have played many nights with a thin and unpleasant tone, even worse with a sparkling, clean sounding strat.

Note that the range of most Fender models is 1 to 10, while the model controls range from 0 to 10. For the OCD-crowd, here's a translation table, created by forum member Barhrecords.

Cab Pack 15 and 21 provide a variety of recent Twin IRs.
