I've got a Spector Rebop 5 with the stock EMG Hz pickups. I'm considering replacing the EMGs with a Bartolini soapbar replacement. I believe my particular Model has the Aguilar OBP-1 preamp. I'm wondering what to expect out of the swap? Has anyone out there done this? The tone has pretty good growl to it already but I'm looking for more character, and a more full bodied sound.
