I have a '69 Ampeg Dan Armstrong-modified Danelectro U1, and the bridge screws have pulled forward so much that even a drop-in intonatable bridge can't make it play in tune. The screws aren't bent; the bridge block screw holes have been pulled oblong. I imagine the best fix would be to replace the bridge block with better wood, but I assume that'd kill the value of the bass, and might be more than I can handle anyway. The next best fix would be to fill the existing holes and remount the bridge in the correct place. Either method requires patching the Masonite over the old holes seamlessly. THAT is my question! How is it done? IS it done? I can't find anything about it here or all of Googledom. I doubt I'll sell it, but as the most valuable bass I own, I'd like to either have the option to sell, or at lest make it playable. I might be able to sell it as is for a good price, but I'd feel much better about selling a tuneable instrument. I'd just like to make sure a repair won't wreck the value. I've never cared about resale value before, so this is an opportunity to learn new skills. Bonus question: How to repair the cracked chrome cover of the lipstick pickup, and maintain vintage value?
