Simple solution to a big problem

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.

Works with V Stand Second Tier!

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!

Boom Arm; What a good idea!

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

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.

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.
