Different strokes, I guess. he must like the sound.I myself am a huge Neil Peart fan but I've noticed how the quality of his drums are sounding not so good. I don't hate DW Drums but I think Neil should really do what he did back then and not use the stock heads on his drums. If he got like a Roll the Bones or Moving Pictures sound on his drums that would be good but I think it's because he stopped using the Slingerland snare. Ever since the Snakes and Arrows DVD the drums sound horribly tuned to me. The snare on the R30 DVD and album sounds godly compared to what it is now. But Neil really should go back to not using the stock heads. But his tech I think has said that his drums are like rarely tuned so that's why they probably sound awful. Neil is still a good drummer but it's just the EQ and what not is really awful.
The information that drums are rarely tuned is incorrect, but his current sound is definitely way different than the old Ludwig or Tama kits of yesteryear.
