A great microphone. I have inly used it for Acoustic Guitar so far. It has great side and rear rejection with little to no bleed from other sounds in the room.
I have been recording a singer songwriter and my other mics, one being a Shure SM57, the bleed from the 57 picked up to much of the singer. KSM 137 did the trick. A side note the Shure 55 (Elvis type Mic), has great side and rear rejection.
You will not regret getting the KSM 137

Great mic great price, Did the jangling key test, rings clear and true.... great for acoustic guitar.

This small condenser mic fits the bill. I record an acoustic grand piano. My Steinway"s volume is big to say the least with all those frequencies! While I don"t know much about sound equipment I do know how my piano should sound. David M, my rep at Sweetwater, knows how to get the equipment for me at a price I can actually afford.

My final thought that any prospective customer should know is that the support after the sale is primo here and a reason I buy here rather than a big store.

Happy with these mics in a big way! Extremely clean and clear that how they sound!!! I also like how small they are... very handy! I have four of these great mics and what ever I put them infront of they sound fabulous!!!!

Over the years I've used a variety of mics as drum overheads in live situations. Up until now I've never been happy with the results. I have two of these, I use one as an overhead and one close micing the hi-hat. I could not be happier. This is the sound that I've been looking for. I use a variety of other Shure mics around the kit and I was hoping that this mic would do what I ask of it. It does this and more.

Bought this after my beloved AKG 451 was stolen. Needed something for hi hat primarily but also for acoustic guitar and piano and this does the trick beautifully. The DB filters are especially helpful, allowing me to drive the pre amps on my Midas a little harder for the best of both worlds. Love getting phone calls from Luke Herian, every time I see that number pop up I always answer "Hi Sweetwater, I mean Luke...". Great service, Sweetwater folks have this down to a science. Cheers!

Yeah I would say this is really good for acoustic guitar mic'ing, cab/amp mic'ing that sort of thing. I already have a 5k dollar tube mic for vocals so I am not using it for that. I also use electronic drums so I do not need to mic my drum set. I really only need to mic the cab, acoustic guitar, vocals. But if you really want a killer mic for acoustic instruments and/or amps then this is the best bet for the price range. Hope that helps.

Amazingly crisp hi frequency responses and transparent small-diaphragm condenser. Attenuation and HPF switches make it truly versatile.

I purchased this mike through Sweetwater a few months back and have really put it to much use. My background is acoustic music and like the other reviewers I have found this mike to work well with guitar, violin, mandolin, banjo, and even acoustic bass. I do a lot of overdubs on my own projects and it's nice to have a mike you can leave set up that works so well for so many different types of instruments. I usually record into a macpro, with Logic 8 through the Duet with no other outboard gear. I do not have experience with the high-end(priced) mikes but I think Shure is one of the best values around. (I also respect the SM7!)

This is a very natural and open sounding mic. It has a slight presence bump around 4-7khz. The low end seems fairly flat maybe tapering off a bit. I bought this mic mainly for close miking hats. Turns out, it's great on acoustic instruments. Banjos and mandolins sound great. Acoustics sound good but I think the Neumann 184 still Wins. but, considering the price difference it's great. And pretty close sounding.

I have used well over a dozen different SDCs in the sub $1000/pair range and the only ones I've found worth having thus far are the KSM137s (and 141s). I kept putting off buying a pair of these, thinking they would perform similarly to the rest. I am so pleased to say I was wrong! While other mics in this price bracket have smeared transients and annoying resonances, the KSM137 is crystal clear, fast and resonant free! Smooth low end and mids, with a just right presence that is NEVER harsh, glaring, distorted or brittle, yet airy and so pleasing. Cymbals sound stellar, as do various acoustic string instruments. If you can only buy 1 pair of SDCs on a modest budget, these are it! You wont out grow them either, as even if you have popular high end SDCs in your cab, these will still find lots of use! Given that the stereo kit of these is well under $700, I find this to be the best value in SDC mics around and one of the best values in pro audio period, only to be bettered by the sub-$800 priced dual pattern KSM141s.

LIke another reviewer, I have been able to put this mic up against several others when recording acoustic instruments. I have found none better, even those costing hundreds of dollars more. This gives a very "uncolored" flat respsone, yet warm through both of my DAW's (Protools and Cubase). It works equally well on banjo, acoustic guitar, and mandolin. Our banjo player uses this mic in live settngs and I love it when I'm on the board. I'm now in the market for a couple more.

I've had a rare opportunity to a-b several large and small studio condenser mic's in my home studio and compare them to other microphones in my locker. I've learned over time that you can't judge a great microphone on price alone. The Shure KSM-137 has a very smooth and warm low end with an outstanding up-front presence without getting thin, a sound quality that really caught me off guard the first time I heard it. What a gem! Hearing is believing. Of all the microphones I own, the KSM137 is without a doubt one of the most "versatile" microphones for recording acoustic bluegrass instruments that I have used. The KSM137 also sounds great in live performance applications. It is true that there is no one microphone that does every job well. But if I had to be limited to just one small/medium condenser microphone for studio or stage, the Shure KSM-137 would certainly be at the top of my list.
