Haha! I’ve gone ‘round and ‘round with the same dilemma since I started playing! I think others have, too. If I was a high gain player, as I think you once said you are, and used time-based fx like delay and reverb, I’d try the fx loop just to see if I liked it. To give it a shot, you can always sit a pedal on top of the amp and use a couple of short pedal interconnects into and out of the loop. I think Angus or Malcom actually used the preamp from an old wireless device to boost or color their signal before hitting the front of the amp. I don’t know much about it, as I’m not into that style of play, but I’ve read there’s a company making a reproduction of it. Then, too, they had the stuff that could be done with effects at the recording console and FOH mixer when playing live. From the sound of the records, seems that a substantial amount of compression was used to even out guitar levels.
