Asking is free, which for a Dutchman is saying a lot

It is an Epiphone Zenith a short lived model that came with special type of active pickups with special pre-amp(will look this up and tell) , I bought it on a trip to Barcelona. The previous owner thought the bass too heavy and he surely has a point. But it is a very nice bass but as I am not fond of active pickups , I will probably put in other pickups, which is not an easy thing to do on a semi hollow body, Ithink. Suggestions for this project from this knowledgeable group are welcome indeed.
