I have been running an original Marshall JCM 800, (using the pre-amp direct out of the head to bypass the power amp on the Marshall) running it into an original Mesa 2:100 tube power amp, then from the 8 ohm out of the mesa into an 8 ohm 2X12 Framus cabinet. I've been recording the signal through the following chain : an sm 57 on axis (through an api 312), a Senni 421 (also through a 312) slightly off axis, and a Neumann U87 (through a focusrite isa 428) centered in the back of the amp room to pick up some depth. I sum all 3 tones (sometimes 4 if I use an Audix i5 ) into one mono track going into my converter. I have found this chain to be sure fire, every time. Anyone care to comment? Elaborate?
