I've recently picked up a couple of 5 string basses: a Samick (Artist series, PJ configuration and active preamp), and a DeArmond Pilot 5 (most likely Fender era, dual J pickups, active preamp w/3 band EQ). For varying reasons, I'm looking to change out the stock pickups in both, but being that they're pretty cheap basses I don't want to spend a fortune doing so. To give an idea of what I'm after, the Samick I was looking to get a reasonable versatile set of pickups that would be usable for most styles, whereas for the DeArmond I'm really just looking to get a good punchy tone suitable modern rock/metal. So with that in mind what are some decent pickups I could get on a budget? Ideally I'd prefer to spend under $100 all up for each bass. Would a set of Wilkinsons or something do the job or would it make a huge difference going up to some Seymours or similar? I'd prefer not to have to change the preamps too if that helps. Thanks in advance.
