I did a full ‘57 specifiction conversion to my 1978 LS-50. It was by no means a cheap process, but I can attest it was worth every cent. As far as tone is concerned, it produced an instantaneous night and day improvement. It is now by far my best sounding guitar plugged in and is everything you’d hope a vintage Gibson to sound like. If you are genuinely invested in doing this conversion, I would advise you overhaul the entire guitar. Not simply replacing the electronic components. As, I believe the most contributory factor to achieving “burst” tone lies in the anchoring of the strings from tuners to tail studs.
Here’s the parts I used:
50’s Kluson tuners,
60’s Gibson wired abr-1 bridge,
Wizz premium clone PAFs,
CTS 500k pots and NOS sprague capacitors,
DMC lightweight aluminium tailpiece,
Gibson 1 1/2” steel stud bushings

Luckily for you, the aftermarket for reproductions of vintage specific parts has moved along considerably. It is now far more affordable to purchase reproduction parts and are readily available from a range of different suppliers. Don’t buy the cheapest or first part you come across, as they vary in quality and accuracy. Do the due diligence and learn the precise specifications and idiosyncrasies of each individual component.
Best of luck to you on your tone quest, brother. Rock on! 🤘
