We compared two new small cardioid models (the Earthworks Flexwand and the 3 Zigma CHI SD-C) as drum overhead mics on a DW Drum Kit. The recordings were done on a single drum take with one of each model in the same place above the drumset. In each recording you are hearing only a single overhead microphone (nothing on kick, snare, toms, etc.) so it's not meant to be a complete drum sound. Just comparing overhead mics here.
Yeah, the Flexwand has more sparkle, but the 3 Zigma is more neutral, more like my drums actually sound in the room. I like them both for different reasons.
The inherent design of the CHI System is to have nearly transparent (nearly color-less) Small Diameter and Very Colorful Large Diameter Capsules. If you want to have Drum OH Leap out at you, try a C-Lol-12 or C-Lol-251 as a Stereo Pair for all but the loudest Drum O/H Applications. CHI is a big Crayon Box !!!
The Zigma was alright but didn't move me. I wonder how it sounds in stereo?
