I have two Clapton Strats..(one black, one Metal flake green) Both Stock with the Lace sensors. I just recently compared these to the new "noiseless" PUPs. I think the Lace sensors sound brighter. IMO Better With or without the Preamp. I don't use the preamp that much I actually love the necks on these guitars. Both have been refretted with 6105 wire. I LOVE these GUITARS!!!!!!
