ObsidianWire T 3-Way Universal Spl. Harness

Installed this piece of electronics. Looked like ok quality, nothing exceptional. Very poor quality instructions, the leaflet showed how to connect to a 10 pin Block, even though my part had an 8 pin Block. Confusion right there. Eventually figured out the connections, quite fiddly, but not too bad. The disappointment came when everything was plugged in. Extremely noisy. Tried humbuckers, single coils, P-90s, stratSS, filtertrons,...... You name it. Basic sound through amp was ok, but Extremely noisy. Have gone back to just soldering as usual with my old pots, no problems and quiet as it should be. I like the idea, but the excecution and quality of this product is just sub-par.
