Bought my Washburn Parallaxe 6 string a while back equipped with a buzz feiten system, decided that i want to tune it low (drop a,b etc.).

I went ahead and purchased some dunlop heavys (10-60) but the damn things don't even fit into the tuning holes like they do on my Schecter.

Anyone got a guitar with this system in it? I don't really know much about it, maybe i am doing something wrong or maybe it just isn't compatible with the heavier strings.

Any help is appreciated

This has nothing to do with the Feiten system. Many machine heads simply aren't bored out enough for a larger string. You may need to alter the tuner (not recommended), buy a new set of tuners (or just a single, if it's only one or two strings that won't fit), or go back to a skinnier set.
