First thing I did, was drill & tap the bridge height screws, machined brass washers, and installed a vertical setscrew. Then I had the tremolo block machined to lower the E and G string holes, so they have maximum downforce against the now locked down and stationary roller bridge. I also removed and reglued the string spacer (above the zero fret) with urethane glue.
The results were much more sustain, much more tone, and way more resonance, and a better setup as string height can be lowered if desired.
To finally have Mosrite tone (I rewired the guitar like a Ventures model) with Gibson sustain and resonance is a dream come true.
If anyone is interested in having this done on their Hallmark, I could figure up a price. It does no damage or non-reversible modifications to your guitar. The trem is the only thing that gets any permanent machining.
I'd like to think of what I did to this guitar is kinda what Carroll Shelby did to a Mustang
