Ok guys, i am thinking of getting some pedals. I have a peavey xxx and a jackson ps1.

Anyway i am looking for a overdrive pedal to boost my xxx's distortion. I am looking for a slayer type sound, i am also thinking of getting the mxr KFK 10 band equilizer. I can either get pedals or get a RR3 with the emg KFK pickups in it, any suggestions.
probably a new guitar if you dont like your current one also an eq may be a smart move but if you insist on getting an overdrive get one
