i really dig the feedback tones in the middle,
just enough gain,
the mini rec can obviously get very close to early mark or even dumblesque tones with the right settings
I think the MR does do a pretty good job of getting early Mark (like Mark I) type tones, too. I've had the Mini Rec for 4 years now, and I'm still in love with what it does; just perfect for what I do both recording and with my trio. What I've found works best is 25W setting (the 10W setting is just too compressed, squashes the transients), "vintage" with low-ish gain (9-10 o'clock), high channel master (around 2-3 o'clock) fed by low output PAFs. I also fitted a 12ay7 in V2; seems to soften some of that Recto edge on the OD channel. I keep the bass around 9 o'clock, mids around 1-2 o'clock, treble around 11 o'clock and presence dimed. I also use a Fromel Shape parametric EQ in the loop to boost some upper mids and treble. That's my go-to setup when gigging with my trio, slight adjustments according to the room etc. That's also exactly what I used for the feedback section.
For the rest, including the solo, I took a slightly different approach going for more of that Dumble-ish vibe. I run the Mini on "clean" @25W with the gain around 1-2 o'clock and the master dimed, the rest of the tone stack similar to the OD channel. With the guitar volume wide open it clips nicely; good, classic rock type crunch. To get the D-amp thing I run a Wilson Lotus Drive (like a Zen Drive or any other D-amp type pedal) with the gain all the way off, level at unity, so it's more for that sparkle than actual OD. For the first verse I had the guitar volume just cracked open @1-2, 2nd verse it was about 5, neck pup for both. For the solo and final verse it was both pups blended to just give a hint of clipping but still sounding clean. Again, the Fromel Shape in the loop.
I mic the stock Mini 1x12 cab with a Rode M1, basically an SM58 clone, with the wind screen removed so it's basically a 57.
Then just a bit of compression (just to even out but not destroy the picking dynamics), delay, and reverb at the board.
