I have a parts bass, it started as a epiphone p-bass but now has a refinish and lots of other mods. Currently I have bassline quarter pound P pickup and a Bassline quarter pound Jazz. I am looking to install a preamp into my bass, the dilemma is I am getting married in June, so I need to do this on the cheap. Anyone have suggestions? I am just trying to get a little bit more tonal variety, with no specific goals other than filling my need to mod.
