      Modeling Mics That Work for You

      The SP-1 pair and included Hemisphere Mic Collection software work with or without UA hardware, and go way beyond subtle EQ curves to give you precise control over filter, proximity, and axis — an industry first. Just set them up in front of your source and use the plug-in to find that “sweet spot” for an acoustic guitar or piano, or tame harsh frequencies on drum overheads and more.





      Your Go-To for Stereo Recording

      SP-1s feature a classic cardioid design, high SPL tolerance, and smooth, clear top-end — delivering consistently clean capture of acoustic guitars, drum overheads, percussion, horns, and more in any environment.





      A Rugged, Dependable Pair

      Engineered to be your everyday choice for stereo recording, SP-1s feature a retro finish and road-worthy build. They’re equally at home on the stage or in the studio, and pack vintage elegance for days.

      Sound good, but too noisy

      These mics sound great, they look really cool and if you are going to record loud sounds as drums, guitar amps, loud acoustics, orchestra, etc. they will work fine. In my case, I'm currently using them to record acoustic guitar picking, upright piano and other acoustic instruments. If you need to record very intimate performances, forget about these because the amount of noise they make will mess your recordings up, unless you are searching for this "hiss" effect.

      Good microphones overall, they are just not made for quiet performances.

      Good sounding mics, just need a little overhaul (noisy noisy noise)

      I have to use extremely high quality cables (equal to the mic value) when working with these mics as they are so fussy and noisy. When they are working and the sound is clean, they are great.

      Sp1, both faulty when delivered brand new

      A disappointing first impression of these mics. The quality control isn’t what I expect from UA. I use several of their various units, digital and analogue, and am otherwise very happy with those. Regarding the mics, one was profoundly noisy and scratchy and on the other the XLR connection didn’t want to latch even under force, so these have gone back and it’s unlikely I’ll get another pair as I feel I don’t have much trust in their construction.

      These Mic's are incredible

      You can find this quality of Pencil Mic's for This price! They sound amazing!

      For the price I love them

      I'm changing my review to 5 star as my Sp-1s were faulty and replaced. I just got done testing them on several different acoustic guitars and they sounded great. Even using just 1 of these to mic an acoustic sounded brilliant. My ear isn't as trained as many here but what I hear I loved.

      Tentative 3 star

      I just spent 1 hour with a new pair of these and they are picking up an extreme amount of noise even when the preamp is at 0%. The noise isn't similar as one of the pencil mics is picking up 3 times more than the other one. My studio is treated and these is nothing that a microphone can pick up. I've changed out the cables to several different brands and used two different apollos (the X8 and the MKII) and the issue is on both. I've even plugged in other highly sensitive condenser microphones which are working perfectly. I'll change my review once I hear back and if mine are just faulty.

      New overhead mics!

      I just swapped my large condenser mics to the SP-1's and I'm so happy I did, normally I prefer large capsules but these sound amazing. Can't wait to try it on other instruments!

      Clear, detailed, neutral sound.

      Exactly what I want in an SDC—playback sounds like what I was hearing in the room!

      measurements

      Unfortunately, there are no usable data sheets or diagrams on the frequency response or directionality of the microphones. Information that should be expected even in this price range.
      UA should definitely provide a reasonable datasheet here as soon as possible.
