Oops! (check pic)You're gonna have a hard time finding anyone here who has actually replaced their bridge with an aftermarket one.
I prefer a "quick release" type of bridge and it actually seems to resonate better with this one anyway (go figure).
And since none of you can come up with a better answer than: "Don't touch it. It's precious." to the original question, I'll do it for you.
No. There, to my knowledge, is not a direct replacement due to the fact that the Lakland body and bridge have holes that run at an angle, not straight across like other string thru capable bridges. The lower (pitched) the string, the farther away the hole is.
