I'm wondering what gear or instruments you feel are - or will become - timeless tools of the trade, things that always can be found in studios and on stage? Things where you sort of can't go wrong if you buy it? I have a few obvious ones that people come back to, like Fender P and J basses, MusicMan's, and Shure SM57 and SM58 microphones. Ampeg SVT and 8x10 in the amp department. I believe the SansAmp Bass Driver DI will become one of those standards, if it's not already. Can you think of other nominees?
