Tell me more about this bridge…

Korean made, early 2000's.

 

This. I have one on my Artisan B4FL. It took some help from friendly folks on here to figure out how to lock the string saddles in place, since it's a unique design.

 

wow, that tailpiece seems to be hanging off in space there.

barts are good

 

It's called a Fortress Bridge, I had one on my A6 from around 2005. Not sure if's proprietary or who made it, but my guitar tech was impressed with it.

 

The Kubicki saddle assemblies were similar. The saddles are threaded for up 'n down and the cap screws are the lock-downs once you've dialed-in intonation.

 

Actually the string retainer is recessed into the body. It's solid.

Not these MK1s so much. My guitar tech has it right now, swapping those out for MK4CBCs and a NTMB+F preamp.

The cool thing about the notched string saddles is that there is a brass pin with a rounded top that the string sits on. It really helps the strings ring with great clarity, IMO.

 

See the hex screws adjacent to each saddle? Find the properly-sized hex key and insert...you may have to slacken and remove each string for better access (PITA). Caution: the hex screw may be a reverse / left-hand thread so don't force. Loosen the lock-down hex screw and each saddle will move to & fro with some thumb pressure. Once the intonation is dialed-in, re-tighten the lock-down. It appears the E saddle has been reversed to better accommodate the normal "retreated" position.

Had a luthier do a set up right after I bought it, over 15 years and it never needed to be adjusted again. That being said, I used the same brand/gauge of strings the whole time I owned it.
