After discovering that I find Rickenbackers more comfortable to play than the other custom instruments I own I had a thought. I love the Ric sound and the amazing neck through sustain so I'd like to keep my present 94 Fireglow Ric as is and buy another for modification. Has anyone tried completely changing the electronics of a 4003 beyond switching pick-ups? Would it be possible for example to fit a 2 band pre-amp and active pick-ups and get a modern sound? I know the 4004/5s have hb pick-ups etc. but I don't like their looks at all. For me the 4003 is the ultimate Ric look. Also, I've heard that the stock Ric bridge is the weak link in the design and would benefit from replacement. Has anyone done this?
