I've been using Shure SM57's on toms, many different kits, many different players, and no matter what I can't get a good tom sound. I know my room and pres play a big part, but I recently stopped using the 57 on snare and now use the Senn E609 and get the sound I want. I'm thinking that it's more so the mic and less of the other factors. Now... How does the Audix D2 compare to the almighty MD421? Obviously the difference in price is about 3 fold, and one is the industry standard, but a lot can be said for an underdog. The tom sound I love is pretty much your commercial rock/metal tom sound. So would you even put these two mics in the same ball park? How would you describe the sound of each on toms?
