The treble bleed, or bypass mod will definitely help. All pickups, unfortunately, lose some treble when you roll back the volume. BKPs suffer much less from it, but it's still there. I have a Mississippi Queen in the neck of my SG Standard, with an Abraxas in the bridge. I found that the treble loss was not excessive, and certainly not enough to require a treble bleed mod. With the stock pickups, and all the others I tried (Lollar, Fralin, Duncan, DiMarzio, etc.), the treble bleed was a necessity. You won't be disappointed with Bare Knuckle Pickups.
