I think you can install a mid control like this: John East - Mid Sweep - Best Bass Gear or this VMC or something similar in addition to your preamp. Just wire the signals from the bridge volum control and the neck volum control together and connect to the mid control input. Connect the mid control output to one of the preamp ... ... more
