I owned 70's and 80's Rics until the mid 80's Bought a new one in the late 90's, and thought the tone had drastically changed. I now own one of the newer ones, with push/pull pot. I still don't think it sounds like the older ones. Is it just me, or do the 90's and current 4003's just sound much darker than say the 80's, or even 70's 4001's? I don't want to change out the pickups, but could the existing be rewound to give a more clear tone? If so, what would be the key to successfully pulling this off? Thanks.
