Great replacement for the original LTD EC 401 bridge. The original got rusty over the years and the saddles couldn't be used anymore to set a correct intonation as they got stuck.
The TonesPros T3BT-C is just a perfect replacement: fits perfectly on the original posts (I didn't even need to replace those with the ones coming with the new bridge), plus I could tighten the two smalls screws on each post to secure the bridge so it doesn't fall off if I remove the strings and turn the guitar upside-down.
I needed just to file the slots for each string for the correct gauge. In fact, although the saddles are pre-notched (and the spacing is perfect for the EC 401), the strings would slip over the slots because those are not deep and wide enough. The whole process took me not more than one minute though (and it was the very first time that I was doing that): you'd need just the right tools (I used the Goldo Double Edge Nut File bought from Thomann).
After the replacement, I was able to get a perfect intonation.
The sound changed and now is fuller on every string, with some more middle (more Gibson-ish).
Way way better than the original bridge! Highly recommended!
