Got my TZ and AN in my RG421 - DAMN!!!
Well, I finally got everything in there, after waiting several weeks for the pickups to come in.
The 5 way switching sounds incredible, there's not one useless position. The pickups are unbelievable, no wonder it's such a popular combo.
The 421 plays even better now, since I removed the tone control and put the volume nob in its place, leaving plenty of room for me.
I love this guitar, and I can honestly say I will never part with it, it is the best playing and sounding guitar I have ever owned.
