The Fall '03 issue of Double Bassist magazine contains a photograph of Rainer Zepperitz, retired principal of the Berlin Philharmonic, with a bass that appears to have a laminated bridge. No adjusters, just a black line that suggests it might be a sandwich of maple on both sides of an ebony core, of about 1/8" thickness. I've never seen this before. Anyone have any experience with these? I'd guess it would be stiffer and more warp-resistant, I'm curious to know how it would affect the sound of the instrument. Brighter, maybe?
