I've posted "60s Fuzz Jubilee" on the Rig Exchange. Even if you don't like to use fuzz, try the amp with it bypassed. It is my Jubilee, time warped back to the '60s, with an open 2-12 cab from the "AGL Marshall" rig.
I heard a sound clip in another thread of the Lovepedal MK12 Chrome. It is a "vintage parts inside" fuzz, in the tradition of the Tone Bender. I combined the Muffin and a Bit Shaper before the amp, with another Bit Shaper after the amp to get a little closer to that kind of sound.
The sound clip is the Marshall and Bit Shapers first, and then with the Muffin added.
