Re: kelly shu
The fact is, mic placement is what helps get a good kick sound, and the Kelly Shu doesn't really help with that.
What it does is to keep that placement absolutely consistent night after night. Given that just an inch difference in placement can make a huge difference in the resulting sound, consistency is crucial.
If you use a flat mic (Shure or Sennheiser) like I do, they have now introduced their Flatz series to accommodate them. I am thrilled that my kick 1) sounds the same every night and 2) the mic no longer slips down the side or between the pillow and head, which meant the kick would disappear. Also, the mic just lives in the kick, it doesn't have to be placed or removed each night.
Big fan of the Kelly Shu!!
