Hey all. A Friend of mine was wondering what some good options would be for replacement PU's for his Warwick Corvette pro 4 string. J-bass style PU's, so I'm sure there's limitless options, but he's just prolly just looking for an upgrade from the MEC's. I've suggested S-D's because of success I've had witht their MM pickup. The bass has the MEC Preamp, how good is that compared to a good S-D, Bart, or other preamp? Plus some approx prices would be nice, like I said...it's not mine, and I'm just doing some research for him. Thanks all!
