i've used them. they're not bad, not amazing, but not bad. i'd say their definitely worth what they charge for them. decent cheaper alternative
I never had a set of the Cruncy's but I do like using their Vintage Extras as replacements for a lot of guitars. I also like the tone of their Classics as well. IMHO GFS makes top notch pick ups for a lot less than the boutique ones costing hundreds more. Another pup you might want to check out are Rockfield I really like the Fat Ass pups and the Mafia. I usually get those for some of the higher end guitars I work on.
