I used my 56 Goldtop Les Paul thru an AC-30. No effects. This combo sounded fantastic at that time. I use very thick strings. The solo was played on the lower strings up high. The room we were in had a tall ceiling with a wooden plank floor. The drummer sat in the archway, his kit essentially in the next room with a marble floor. Bill Dillon was on the guitorgan. Just the magic of the day.
