I have a GIO series Ibanez 4 string with pj pups. I'm using Steve Harris flats which have increased the quality of the tone tremendously, but now am trying to decide on a good set of active pups to go with. I'm just a beginner so I know a lot of the sound issue is caused by my inexperience, but the added sustain would be nice with a set of actives. I don't have a problem with doing a little Luther work so going to soap bars wouldn't be out of the question. I'm mostly into metal, so I'm looking for an aggressive growl. Thx for ur help.
