    No more Musician's Gear

    I bought one of these to see how much difference a slightly more expensive boom arm could make over the cheap basic ones we all start out with. This is way better and worth the upgrade. The counterweight is a nice touch. No more Musician's Gear and On-Stage for me.

    Solid boom

    These are a great upgrade from basic booms. The counterweight balances most mics well, and the clutch is solid. Being able to replace parts (threads, clutch, thumbscrews) is a huge bonus, and extends the life of the gear.

    New Boom arms

    A lot of boom arms that come with standard microphone stands don't handle the weight of some of the heavier studio microphones.
    The Atlas boom arms have got a reasonable counter balance weight and also the locking/adjustment mechanism is robust and the extension arm work well and appear to be designed to last.

    Works well with a tripod base

    So I bought a 12 and a PB21 to give myself a more heavy duty and beefier stand for my large diaphragm condenser which I use for my overhead on the drums. Well, it's less stable when actually extending the boom arm to where you need the mic to be, than a cheap On-stage stand! Pathetic!

    The boom arm itself is pretty solid in construction, UNTIL YOU GET TO THE PLASTIC KNOBS. Plastic?! I could have bought three stands for the price of this BOOM ARM that have plastic knobs on them.. I don't care how much money is saved, how "comparable" they are to actual metal knobs, plastic does not belong anywhere on a stand this expensive.

    So, having purchased a build-it-yourself microphone stand from Atlas, I had to frankenstein it in my studio to get both of the pieces to work. I now use the MS12 as a base for my Guitar vocal mic, with the smaller foot print I can put it right next to my pedals without moving pedals around, great. However, that's literally the only benefit I have from owning a straight stand from Atlas, not worth it.

    I can ONLY use the boom arm I purchased, on an old on-stage tripod base! FeelsBadMan

    If you've seen my MS12 review, the only reason the PB21 wasn't returned was because besides those god awful plastic knobs that should not be within 100 miles of this company's factory, the metal construction and the counterweight are actually very solid in construction.

    Check the MS12 for the first half of my review with the boom portion!

    Measurements are a little misleading

    Just got this, so can't evaluate the clutch yet. Seems quite solid but it looks totally conventional, so I don't expect it will be any better or worse than any other decent brand. The lever is long enough that you can get a bit of torque on it. But you really don't want to have to rely on the clutch to hold your mic up.

    The actual extension though is not 38" it is only about 28". With a common or garden mic clip, it comes to about 31". 38" is in fact the total length of the boom, including the weight.

    This means it won't extend from the treble end of my 88 to sit over middle C.

    It will extend from the bass end, but if you have a board with a mod wheel etc down there it might be a problem - you might have to finagle it in behind. In my case room there is limited because my top board is only slightly shorter.

    From the bass end, I can allow 4" above the fixed weight for a detachable three pound weight, and it then balances my Sennheiser e855 nicely. That is a reasonably typical vocal mic for weight. Having got it to balance, I can experiment with putting it behind my rig, where the clutch is out of reach, since I should not need to adjust it all the time.

    You have to reverse the clutch, of course, and the actual clutch cannot be reversed. But the "fixed" weight comes off with a supplied allen key and you can turn the whole clutch assembly round. Reattaching the weight proved simple - there is a hole the allen key screw goes into, but I think I got it in there easily enough. That puts the lower tube locking knob on the back, but that is not a major problem.

    I use the weight with my existing, longer boom, but with that I have to have significantly more sticking out to balance, This will be less of a hazard on stage.

    So it works, even in the way I am using it, which is one of the more demanding uses of a boom. The construction is comparable to my existing boom that I have been using for years (the rubbers on that have perished but the boom is still sound) so I expect to get years of use out of it.

    Because the weight is removable, and the rod extends all the way to the end of it, you could remove that and put a heavier weight on if needed, so it gives you quite a bit of flexibility.

    Hey, It's a Mic Stand

    Seems to do what it's supposed to. Notice that the lower tightening gear always turns the entire lower vertical assembly when I loosen it to move the upper vertical up or down. Kind of a bummer. But overall it's just fine.

    Atlas Sound PB21XEB Adjustable Boom

    I own an older made in USA version that's wonderful, so i thought I'd get another & use them for drum overheads. The new made in China one, along with the matching expensive stand, is a complete piece of crap.

    The boom won't move without a fight. The knobs are almost completely useless, as they don't really tighten down all the way. It seems like the tubes are bent, warped, or somehow not straight as they won't slide easily like they're supposed to. How hard can it be to make straight metal tubes and proper knobs?
