Thanks again. It's good to 'talk' with people who have far more knowledge than myself. I've just listened back to a recording I did of an amplified jazz trio a couple of weeks ago. True, the sound reproduction from the Sony ECM MS-907 was crystal clear in the treble frequencies and not particularly bassy. However, the bass is there and I could always boost the bass frequency via EQ on my computer/stereo? I've been reading some other forums where people have had problems with an overload of bass and as a result, distortion (due to bass-friendly mics?) so I'm wondering if, with regard to mini disc recording, the MS-907 might be an acceptable compromise between crystal clear sound and undistorted bass-reduced recordings. Does anyone believe the Sony ECM MS-907 mic is a sound (pardon the pun)purchase for high quality semi-pro recordings or should I really trade it in for something else? If so please let me know soon as I only have 5 days' in which to return it if I'm going to change my mind. Many thanks for your unbeatable knowledge! (Sony - take note: THIS is good unconfusing customer service).
