First time posting here, and kind of a unique question I think: I just got a used Rickenbacker 4003, and I'd like to be able to rest my thumb on the top edge of the bridge pickup (I'm used to playing a bass that has J-style pickups). The chrome plate that surrounds the pickup is basically a big rectangle that sticks out - it's not flush with the body of the bass: I installed a trebel bezel (http://www.pickofthericks.com/products/Treble-Bezel-for-Rickenbacker-4003.html), but I still feel like my right hand is too high above the strings. Anyone know of somewhere where you could get a pickup plate that is just flat, flush with the body of the bass, and would leave the edge of the bridge pickup exposed so I could use it as a thumb rest? I'm open to any ideas at this point. I'm to the point of looking into getting a piece of metal custom-machined for this purpose, but want to get some feedback before I go that route! P.S. - just to be clear, I'm not talking about the pickup cover that comes with the bass. I removed that already, as most Ric players seem to do!
