Fuck I still need to do this mod... my friend has a Washburn WG587 something-or-other 7-string with a 707 in it (which I advised against) and his guitar was always wayyyyy too gainy, I noticed his pickup was really close to the strings. I made him lower it, which helped but it was still super gainy through settings on an amp that were fine for my EC1k with an 81. He did the mod and came back and it really did make a big difference in the headroom. Now I can actually tolerate hearing him jam in the corner, haha. Now if there was a way to make the 707 not suck he'd be in business...
