This review was written about the AT835ST and AT815ST. The models were changed slightly in 2007 before being renamed the BP4029 and BP4027, respectively. In the rapidly changing world of pro audio, taking things for granted is not a good idea. If you think you know what to expect from a stereo shotgun mic, you might accidentally dismiss Audio Technica’s 9-inch AT835ST ($899) and 15-inch AT815ST ($999) mics.
