I am looking to switch around some op-amps on some pedals I have - They are both socketed A Lovepedal eternity - At first I thought this one was broken when I got it. I guess I was expecting more drive. I switched this one for a JRC 4558d (new issue) and it sounds better but there is just too much noise. and the Hermida Mosferatu - This one sounds good It just needs more punch. I would like to have some more compression in both of these but I suppose that doesn't have anything to do with the op-amp. I just bought the Eternity but I can't get them to answer any of my emails. So I guess I am on my own. Any help would be great!
