Congrats on the find that's really awesome!!!
The older pedals seem special....I mean with the HB I clearly love older ones made very early on but those did have some parts differences as the circuit evolved.
My current EGDM 3k is much newer. So maybe I won't notice as much change, can't wait to find out.
Hey one thing is for sure, we all seem to really love the EGDM. Personally I like the way it adds compression like a pushed amp/speaker & the dynamics of it. I find I have my preferred setting but still dial in many different ways. Never leaving my board!
