The AEA is the RPQ-500, great pre; love the EQ on it. You get exactly what you hear in the room
with that on either of the Ribbons. The Great River is a fine piece of kit as well.
I go to the 121 probably because its size and ease of set up, the 84 is a little awkward with the built in cable.
Thanks on the tracks btw, Billy Leach is the writer/performer on Full Moon.
He also did the steel work on Crossroads, my lap work was/is a little weak.
Maybe I should practice a bit?

I much prefer the Blumlin Pair technique to the mid-side stereo.
I added a little "sweetener" on the Full Moon mix,
but basically it was "gorgeous" on the monitors going to disc in the control room.
Probably should have put up a room mic for the verb...
