I owned a LP with a Kahler and did not experience this “tone suck” thing. Not disagreeing…just relaying my experience.It depends on the design. Rollers on a strat style bridge change the tone but not always worse. The real thing is they aren't necessary to fix the issues and they take a bit of the top away . Rollers on any design that the string moves across for vibrato are a huge tone suck though (think Kahler.)
