I bought not so long ago an Ibanez RG420FB
I'm wanting to progressively change/add some of the hardware/electronics on it
I just don't know where to start

-Bridge: It's an Edge III i thought about adding a tremol-no to it to increase the tuning stability. good or bad idea??? should i change the whole bridge??? i heard you can fit and OFR in???

-Pickups:I mainly play metal but i really want a good clean sound to keep the guitar versatile I've done some research, red the pickup guide, but still not very sure
I thought about a dimarzio evolution for the neck and something with higher output for the bridge, like an EMG or a Blackout

So where should I start?

for the curious, I'm playing through a Peavey XXX 112
