I wanted to replace the stock 3 springs in my floyd, for two springs. I wouldnt say these are massively high tension, but they offered more resistance than the stock springs, though I did have to screw my claw in about 6mm ( I was unable to get this tension with two of the stock springs, even with the claw screwed as far as it could go which was about 12mm travel). So plan worked, hhappy with these springs. Noise wise they do work. I didnt remove any paint but its possible my tremory is doing the grounding?
