Well,I have done two hard gigs with my 812e with ES2 system.I used this with a Roland AC60 acoustic amp.
So,I did get a very good sound,but it took me about 10 minutes to get a very natural sound.This entailed adjustments to both the e.q.controls on the Roland and also the tone and controls on the 812e.
The sound was very natural / acoustic and fairly warm once I dialed out the unwanted frequencies.
I had the master volume and the individual channel volume controls on the Roland AC60 at just over half and did encountered no feedback at all.
Hope this helps folks that are new to the ES2 system, which i do like a lot.
