    This is no KM85, but if you're on any sort of budget, I would strongly recommend this mic. It sounds good on acoustic instruments, putting out a bright, but not too much so, tone on anything that would normally take a small cap condenser. But allow me to tell you a story... I recently mixed a 7-piece band on a board with 10 mic inputs. Needless to say, I was very crunched for space. So for the drums, I put an Audix D6 on kick, SM57 on snare, and a Sterling ST31 as an overhead. I wound up not even using the snare channel; the ST31 worked amazingly as an overhead mic, picking up everything beautifully (the channel was compressed to hell, which helped). The snare actually sounded better in the context of the show through the overhead ST31 than with the 57. The drummer was fairly aggressive, and even with the channel gain set to minimal, I was still clipping on snare hits. That said, I never heard any distortion whatsoever. My one complaint about this mic is definitely its low SPL limit. However, the upgraded version, the ST33, has a built-in pad, and I'm definitely looking forward to trying that one out.

  • Economic Device to Amp String Instrument on PA System

    As reviewed by Ziggy Arnold on 2/24/2009

    I play double bass in church, in which I bow, orchestral style. We have an elaborate PA system. I had used pick ups, which made the bass sound raspy. All other strings are on microphones. Sunday, I used an ST31, and ran it into the board using phantom power. The mike delivered a strong, deep clear signal over our PA system (we have six cabinets, each with two twelves and other speakers. Our sound engineer said it was the bass sound he ever got out of my bass. I highly recommend the microphone if you need a mike for your accoustic instrument. Regards, Ziggy

    Bought a couple fo these to use on Drum Oh's at church. Pretty decent soundiong little mics. I didn't find them to be overly harsh, and they picked up the kit well, without too much bleedthrough. Also tried one out on Ac Gtr in my studio. Sounded pretty good, though a tad boomy too my ears, but nothing I couldn't eq out. All in all, pretty good little mic for $100.
