The Fender noiseless were a nice try, but a tad brittle next to Boss Duncan's offering. They just work for me. I have not tried the latest revision of the Classic Stack, as mine are from 2001 or so. What has changed? I'll likely be dropping a set in a recently acquired 2005 American Deluxe V neck. It has Duncan Antiquity Surfs in there now. Great pups, just not exactly what I need. I'll put them up for sale here later if anyone is interested.
