i have one that i got for $200 new about a month ago....so far i like it, but i haven't gotten to try it with my #1 amp yet (i'm a college student and my main amp is at school and i just haven't had the opportunity to try it yet). the stock pickups don't sound too terrible, but i'm planning to replace them anyway. i like the neck, but i've also played around with a couple S-7420s in stores, and i really like the wizard-7 necks on those....a bit thinner than on the AX7521, but both are quite comfortable.
i've got a recording i did with it, but i can't get to it today b/c the website it's on is being a bit stupid today and not letting me access it.
also, i'd recommend moving the strap pin from the upper horn to the middle of the
neck joint, helps the neck-heaviness problem a lot.
