My existing bridge which had no adjusters previously installed. (so, essentially, a fresh bridge.) Absolutely no degradation in the tone whatsoever, at least to my ears. Actually, my first impression of the tone after having the adjusters installed was, "Wow, they actually make my bass sound BETTER than it did before, more open." Makes me feel silly for being so standoff-ish about adjusters for so long. And the amplified tone is fantastic! I had a Realist, which I always liked (still do) but didn't care for the occasional feed-back issues, so I had the FC installed threads up/elements down. The FC sounds every bit as good as the Realist for pizz but less dark/boomy in the lows and a much sweeter midrange than the Realist. Haven't gigged with it yet but I think I'm gonna be very pleased.

(btw J, let me in on the joke; TL;DR? I sense a bit of sarcasm. If so, unfortunately, it went over the target's head.)
