  • 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.

    Hey, you get what you pay for. I bought a pair of these mics for a children's choir in a church. One of them was defective and after replacing it, I was disappointed in the dynamic range. I tried them on acoustic guitars, a pipe organ, grand piano and even tried 'em as overheads for congas. They're treble efficient and lack a little in the 40-300hz range. So far I've tried three and each one has sounded remarkably different. In the end, they are what they are and I'll use one of them more frequently than the other and that one as a last resort. I strongly recommend the MXL 993 pair in this price range.
