Just reporting back in after doing the mod myself. It's a wonderfully effective mod that really lowers the noise floor, making the GE-7 really usable IMO. The amount of noise in the stock version is just not acceptable. Two things to keep in mind for anyone doing this mod themselves: - There is an error in identifying two of the capacitors: the drawing is correct, the instructions are not (I think... I did it late at night!). Easy to catch though. - If you paint your box like I did, be aware that the circuit will not work until it's reassembled and the input/output jacks are connected to the box which acts as a common ground. I tested my circuit while the paint job was drying and the circuit did not work and I figured that I hosed it up. Not so. Whew.... I painted mine a drab khaki and it looks as cool as it sounds! Kinda looks like a piece of military equipment. If you are on the fence about doing this mod (or having Kevin do it) I'd recommend doing it. It makes a huge difference and it's certainly worth the money and your time.
