Hey guys...I need a little help about mod my bass....I want to install a Fender jazz delux pickup on my Ibanez active pickup bass. So there will be 3 pickups on my bass. I want to have full volume control of each pickup individually. So I think I have to change my on board Preamp. Can anyone suggest any on board preamp which will support 3 pickups??? In addition I have a seymour duncan STC 3 on one of my old basses. Can I mod this preamp anyway for 3 pick ups??? Thanks in advance.
