I need an upgrade for my bass, it is a 5-string Warwick currently equiped with 2 passive soapbar pickups with passive electronics(2 volume, 1 tone). It sounds nice, but does not give me the versatility i need. I would like to upgrade to active electronics, preferably with some kind of EQ to give me a little more versatility. Any ideas? The only option i know of currently is the Aguilar OBP-1, but others would be greatly appreciated.
