So I just got a bullet strat as a hand-me-down, wanna get some hard rock tones, maybe even stoner rock, any ideas for pickups or otherwise?

Any suggestions or comments welcome!
Current Gear:
Peavey Zodiac DE Scorpio (Bass)
Yamaha RBX-170 (Bass)
Boss ODB-3 (Overdrive Pedal)
Line 6 LowDown 150 (Amp)
GFS/Guitarfetish for nice budget options.

IMO, it's better to experiment on a cheapie.

That said, your amp is going to make a bigger difference on tone, and if you don't have that down, then pickups are a waste of time.

Me, I would go full size humbucker in the bridge slot if it will fit or a single coil sized one if not. Something higher output like say a Super Distortion or what not. Prol' get one used on ebay cheap enough.
