Wow, this might be just the thing for me... I have a Fender Precision Plus Deluxe with Lace pickups. Great tone that I love. But I have to turn the amp gain up from 9 to 3 o'clock when I use this bass. There is already a 9 volt Kubicki circuit on board, just needs more output. This could resolve my only nitpick with the PPD.Yes
Yes.
Yes
If your current bass is passive you'll have to install a stereo output jack to switch the battery off when you're not using the bass, and you'll have to find a space for a 9 volt battery. If there's not room for a battery, you can route out a hole in the back of your bass' body and install a battery box. I'm sure the Bartolini module is pretty small and will fit in most control cavities without modification.
