My new employer wants me to go active with my bass. Can those who have added the appropriate electronics offer some input as far as brands, do's/do not's, and anything that you think might be generally helpful. This is a '97 American made Fender Precision that has Bartolini pickups in it. I don't mind digging into the body behind the pick guard as needed - this is a working instrument not a 'collector'. I am thinking that I simply need to buy a preamp and have it installed - is this correct? Thanks for any help/advice.
