Hey guys, So I just picked up an Ibanez gio off of craigslist for $150. I know this isn't by any means a gem, but I have been looking for a workhorse bass for my cover gigs. My main bass is a 4 string fender American jazz bass. As great as it sounds, it doesn't give me the beef for some rock songs we do. Plus I could really use the low B. I'm looking at removing the "phat II" preamp that is currently in it and putting an Aguilar OBP3 in it. Does anyone have any thoughts or recommendations? I figure for the price I bought it for would justify me spending another $150-$200 to make it sound more "presentable"
