nothing more to say, everything Negens described (thank you)
Extremely simple configuration. Channel A = clear, crystalline, Fender hard-but beware, ancient grain (Vibrolux, Vibroverb, supereverb, twin reverb except bassman 59). No new (Hot Rod, Blues deville, blues delux ...). All these grains thanks to the push-pull boost the treble and bass and the possible inactivation of the medium.
Channel B = the slight crunch to heavy bluesy crunch of 70-80 years. Metal possible by adding an overdrive.
Easily a beautiful sound is obtained while in the middle. But it may be precisely carved with all the boost and cut filters.
The interest of channel B is having a very hot super crunch and subtle mix between 1 and 5. Above I find it less fine.
I play blues (Clapton), blues rock (Popovic, G. Moore) and the modern blues-jazz (R. Ford). Perfect for all styles. A channel sounds are sublime. Playing on the settings found all the old Fender. Channel B is great for crunch. It should also try to mix the two channels at a time, mixing lightly under the channel B with respect to A and adjusting the gain of channel B at max 5. This is like "crankait" an old fender bottom but more reasonable volume. This setup also allows the famous game volume knob on the guitar. Lowering it nétoie sound and amount on the crunch and a treat.
I play mainly a strat mapple equipped kit EMG DG 20, I kept the medium boost EXG but removed the treble-bass boost SPC that I replaced with a conventional tone control but controlling 3 pickups.
I just bought it. I do not know much, but I have played on many Fender (Bandmaster silver face bassman 59 Field Delux super reverb). I found the spirit of these amps that I do not recognize the new Fender tube amps. I connect the head with a Marshall cabinet closed in 1922 and an HP combo Line 6 DT25.
The model I have played a reverb (much rarer than the model without reverb). It is exactly the same channels as the twin red knob combo.
I bought 550 euros, completely revised. Compared to the argus, this seems correct.
This is a very powerful comprehensive amp (see review Negens). The grain is for lovers of the Fender 60-80 years. Very versatile thanks to channel B
I would do this choice without hesitation because I do not have the money to buy me an old super reverb black face.
