I really wish I could spend a month or so with a Classic, because I've been a daily user of an original 101B for almost 10 years now, as a primary amp.
I agree that the mid and presence, including the assignable presence, is the key to tailoring the sound.
What's so amazing about the XTC is that you could hand the amp to any type of player, and they'd all come back with different settings.
I've known Bogner products since the beginning, but really need more time with a Classic, just so I can assess it. What Reinhold did was strip as much circuitry as he could from the 101B, to create a beautifully pure tube path. But I also know that a lot of 101B owners had their amps modded into Classics, then wish they hadn't. When I saw that happen, it made me think the tone-shaping features were a good thing.
No matter what, for a decade I've had a 101B/Vin 30 next to a Matchless Chieftain as a main rig. I may start using a Blackface Fender as a clean amp....who knows, but the 101B is staying. The only thing I'm going to do in the future is feed that amp different speakers and see where that leads. The XTC was designed around Vin 30's, and I have a bunch of cabs. That means I need to start loading all my cabs with different classic speakers, and utilize one feature my particular amp has...cabinet assigning. Cabinet assigning means I can send my clean channel to an open-back cab, while the gain channels go to closed 412's.
What I need to do, in order to finally dial my rig in is utilize the cabinet assigning. I should assign the clean channel to an open back Fender style cab with Jensens, then assign the plexi and hot channel to a closed back cab with a mix of the best Celestions....maybe even 4 different ones, so I could choose to mic anything.
