A simple AKG D112 suffices on the kick drum, OK the purists amongst you will be saying the older version is far better, I agree. We use this to allow us to get both the old AKG bass drum sound and the new toppier D112 cleaner modern sound. I cheat by using EQ/Simulation to get the old sound, hey they don’t know technology has taken over. It saves setting up two mics. What the heck….use the bits to your best advantage. Personally I prefer an RE20 but but on the road it gets too many knocks for my liking. This gives a great sound that is acceptable too most engineers and the punters hardly spot the difference (there is always one though isn’t there?). Even to this day the drummer always asks which way round it goes. 🙂
