I installed a MSSC Holy Grail harness on my Class 5 LP and it was the single best upgrade I have ever made on a guitar. I liked it so much that when I heard MSSC was shutting down production due to personal reasons, I had to buy another one while there was still finished stock available. For those of you who were around at the time might remember, Bill at ECP took all of Matt's old stock and sold it for him, so this is an authentic MSSC Holy Grail in an ECP Box. It features short shafts and has never been installed in a guitar.
New this was $275, and today they are unobtanium. I'm asking $225 OBO shipped and PayPal to the lower 48.

The Martin Six String Customs Holy Grail Les Paul Harness w/Real Bumblebee Caps
The Martin Six String Customs Holy Grail Harness uses CTS 550K short-shaft audio-taper potentiometers with 10 percent tolerance to give the pot a gradual increase in volume through the entire shaft rotation. Its pots are grounded with 20-gauge bus wire and have been hand-aged, and the harness uses ’50s Sprague Bumblebee .022/400V 20 percent capacitors with hand-aged sleeving.
DESCRIPTION FROM MARTIN SIX STRINGS CUSTOMS:
We spared no expense with these limited edition, prewired harnesses. Each harness is aged to perfection. Our goal was to capture the magical tones of an old burst with the marriage of new and old parts to produce the ultimate Les Paul wiring upgrade harness. No harness looks the same and has its own character. What's consistent is the unbelievably good tone these produce.
Each pre-wired harness includes the following:
(4) CTS 550K Premium Custom Audio Taper Potentiometers with 10% Tolerance. These are not your standard issue CTS pots. Although these are marketed and labeled as CTS 500K, they are actually spec'd at 550K to ensure that pots meter no lower than 500K. These pots have a very responsive sweep and are metered for optimal placement in the harness.
(2) Genuine 50's Sprague Bumblebee .022/400V +-20% Tone Capacitors with hand aged sleeving. These are the real deal. Not reproductions.
Meticulously wired 50's style and properly grounded with vintage correct 20AWG bus wire.
Harness is tested prior to shipping to ensure proper operation.
