Effective solution

By John from Michigan
Music Background: Many years experience playing folk, country, and oldies rock for mainly senior audiences.

This is completely adjustable to the correct height for my SM57 for acoustic guitar. Securely attaches to vocal mic stand. It is a pleasure to play high-end guitars without the "piezo quack", although pick ups are better in settings that are very loud, or where you need more freedom to move around. In those situations I use K&K Pure Mini or Fishman Rare Earth Blend.

Protective padding bg in the clamp

By Danny B. from Nashville NC

Can't believe this does have scratch guard padding in the clamp.

Much better than a separate stand on the floor

By Mitchell S. from Bedford, IN

Using this is much better than a stand on the floor. Much more secure and saves space. The only thing is the part that holds the mic is too short. I had to put an extender on it.

Great for VO usage!

By Mike M. from Wilton, NH

As I'm now getting into promo work, I needed to be able to use either my Ethos or 415t at a moments notice. As manually changing out the mics every time I needed the other was getting a bit tiresome, I started looking for something that would easily allow me to run both simultaneously with each in their optimal position.

To say that this fits the bill is an understatement. :)

An Excellent Solution

By Jack S. from Vacaville, CA

I wanted to get my rack tom mics off the drums and I used this MSA8020 for one mic and the On-Stage TM01 mic clamp for the other. Both I attached to the mic stand I'm using for one of my overhead mics, so I have three mics using one mic stand. I also used the On-Stage MM01 ball joint adaptor on these to dial in the angle of the mics. The boom arm may be 19" but the reach is only about 16". But I was able to take a boom arm off an On-Stage mic stand I wasn't using and that gave me the reach I needed.

Does not swivle

By Jennifer D. from Walla Walla, WA

Love the durability of this arm. However, once connected, there is not way to adjust the arm to swivel. As long as you set it in the place you need, this is a great product!

Upright piano

By Christopher from WI
Music Background: Engineer

Space is limited in my home studio, so I find setting up a forest of traditional boom stands to be a real hassle. I've grown to love short stands and clamp on type stands for reducing clutter. One of these clamp stands now lives permanently attached to the moving handle on my studio upright piano. Perfect placement, done. One piece of gaffer tape to prevent the adjustment handle from rattling, and we are rolling!

Great product, great price.

By Shoheen O. from PARAMUS, NJ

Got this and the On-Stage 13" gooseneck to attach to the back of my 2 tier keyboard stand for an all-in one stand setup.

Clamp works great on both round and square posts up to 1" wide. Its holding up the gooseneck and microphone, no problem.

Nice mic clamp for creating a fast and cost effective mid-side rig.

By Shepherd T. from Michigan
Music Background: Artist

Place your cardioid mic on this clamp-based stand, then position your figure 8 mic below it.

Works like a charm.

Great Item

By Andrew
Music Background: Drummer

I use these as drum over head mic stands. Just simply clip one to one of your cymbal stands on the right side, and another to the left of your kit. They go up just high enough to get the perfect sound!

Great Mic Stand Accessory

By singplay from Arkansas

I use my main mic stand to mount my ipad at a little higher level than those with great/young eyesight. :) I attach the clamp on boom to the mic stand along with a MSA9030 Gooseneck. This allows me to angle the mic more precisely than other setups I've used. Now I have a nearly perfect setup for leading worship with guitar.

Simple solution to a big problem

By Sweetwater Customer from New Hampshire

Our acoustic trio normally plays unplugged into a single large diaphragm mic. We recently landed a gig in an acoustic nightmare restaurant and needed a solution to capture our sound, maintain our single mic close in style and avoid feedback. I clamped two of these to a boom mic stand. We were able to setup 3 SM58s with enough separation to capture great sound but close enough that we could still hear each other without need of stage monitors. We've nicknamed it Hydra and it is a good solution when we can't use our LDC.

Solid

By mOMMA l. from hOUSTON TEXAS
Music Background: 25 GREAT YEARS

I'm keeping it..

Pros: Solid/ Sturdy -- Simple/quick mounting to my music stand and doesn't move- Boom holds the heavy mic and cord in place-- looks nice - eliminates one extra B/S stand -
:
Con: For a saxophonist, the boom is short. It would be killer with about 6 more inches.(took off a star). PERFECT FOR ALL OF YOU GEETAR GUYS.

Handy

By Ernest W. from Bay Minette, AL

Allows you to blend your acoustic guitar with installed pickup for a fuller more natural sound. Attaching it to the mic stand eliminates the clutter of an additional stand. Works great!

Works with V Stand Second Tier!

By Phil O. from Santee, CA

Thanks to Phil Schwan for helping we with this purchase. This works perfect with my Ultimate Support V Stand and Second Tier Attachment. The boom arm attaches securely to the second tier arm and extends easily above my upper keyboard. No more mic stand to carry around!

Handy Boom

By Sweetwater Customer

Great for acoustic situations and bluegrass type set ups.

Boom Arm; What a good idea!

By John R. from New Hampshire
Music Background: Amateur musician and sound engineer

Mounted on a vocal mic stand, this holds a mic in just the right place for guitar, mandolin, or banjo. Reduces stage clutter, and tripping hazards.

versatile, economical - perfect for stereo miking

By Ward J. from Seattle, WA USA
Music Background: Pro and Avocational Musician, Audio Technician 40+ years

This unassuming little "accessory" is better than having a second mic stand in just about any situation where you'd otherwise have two stands spaced less than about 5 feet apart: 1) x-y or mid-side stereo miking - you can get the microphones much closer together than you could with two separate stands, and with the footprint of only one stand. 2) two musicians facing each other - assuming the primary stand has a boom, you can get the two mics arbitrarily close together or up to 4 or 5 feet apart. (Try this with two figure-8 pattern mics; each picks up the ambience of the opposite singer.) 3) Live in a small club: vocal mic on one boom, mic a small amp with the other; no extra real estate necessary for a second mic stand. 4) A-B comparing two mics, or recording with two for their unique characteristics. QUALITY: as with several other OnStage products I own, this is well-built and with ordinary care should last a long time.
