So, what do we have here? We have a heavily modded modern voiced 4 Gain-Stage Rectifier, with a boost on the gain control, which accentuates the mids and the highs and also gives a bit more gain, an adjustable bass frequency pot "Fuel" and an additional tight switch on the Master, which both control the amount of bass that's fed into the input stage(s), a self-explanatory mid shift and a smooth switch, which reduces harsh highs later in the preamp and an attack switch on the depth-control which changes the negative feedback to a similar way like the modern mode on the Rectifier in a Marshall Headshell with Dagnall Transformers with EL34. Pretty much unbeatable, if you ask me. Fair enough, i'm still in a, like you say "Honeymoon-Phase".
In this clip that i recorded a few days ago i kinda overdid it with the fullness. All knobs are pushed in. I had it cranked to MV3 today with the same settings but the "Fuel" on 10 and the gain on 5 with the Deadweald in the Green Channel set like in the Clip. Man, does it rip. The Amp is special. I had many Amps and i tried even more. This Amp's got all i could ask for. Saturation, punch, clarity(maybe not so much in this clip

), string separation, sparkle openess, compression (both at the same time

) it's kinda airy, but it's full, it tracks fast, records well, sits in a mix nicely and i feel connected. You can use it with a boost, or without. It cleans up nicely. It's clanky when you want it to be, but it isn't fizzy.
I just compared it to old(er) clips of my Rev F and my Rev Blue which both use the matching cabs. MF400B with the Lenzifier. The clips have more cut, but they are also pretty fizzy.
Opinions on all 3 please. I'm glad to answer questions.
