Pro Audio or dictionary defined "Presence" as used by Headway should NOT be confused with the controls sometimes listed on some electric guitar and bass combo amps which use the “Presence” term to denote high treble.

Increasing bass, low mids and possibly high mids, may further obscure any remaining “quack“ Additional methods to reduce piezo “quack” include: i) seating under saddle pickups better with an even string to string balance and ensuring that the saddle does not keep shifting about against the pickup as you play ii) enabling any guitar saddle to be able to fall out under its own weight when destrung, but not loose enough to be pulled forward...
