I always thought it interesting that people get similar tones with different settings.
For me, the best starting point for the rectifiers is noon across the board. You might wind up setting it differently with tweaking, but at least you get the spirit of the amp there. My Mark experience is very different. With that, you have to start out with mids and bass lowered.
My current settings on the Mini Rec (for classic rock) are:
Clean
25W
Clean or pushed, I go back and forth
Gain 12:00
Treble 1:00
Mid 10:30
Bass 1:30
Presence 12:00
Lead
25W
Vintage
Gain 10:30
Treble 1:00
Mid 12:00
Bass 3:00
Presence 12:00
I also have a Tung-Sol 12AX7 in V1 and Mullard EL84.
I played it through a variety of cabs, including 4x10 and recto 2x12 with the same settings. For my RV25 I had a combo which really altered the tone. I had to work on the treble and bass quite a bit. I wish I had put it on top of a Thiele and had NOT put it on a stand. It's amazing how much bass you lose when you pick an amp up off the floor.
