Hey! So, if you're thinking about the On-Stage MSA9505 mini-boom for heavier microphones, it's worth noting a few things.
Our research shows that it does fine for typical setups, but when it comes to handling heavier mics—especially in horizontal or side-address positions—it might struggle a bit. The Posi-Lok system does a nice job of keeping the joints tight, but the telescoping arm can sometimes sag or rotate if the load is unbalanced.
For front-facing and balanced mics, this mini-boom generally holds up well. People seem to like the Posi-Lok system because it helps prevent joint slipping, and the ergonomic knob makes adjusting the boom's angle pretty easy.
But if you're working with heavier mics or need extra stability, you might want to check out other options. Some booms out there come with reinforced locking or fixed arms, which can be more stable.
The construction quality, like around the welds, also seems to come up in our research as something to consider for durability and load capacity.
In short, if your gear is mostly light and balanced, the MSA9505 might suit you just fine. But if you've got heavier mics, especially ones that are top-heavy or side-address, a boom designed specifically for those conditions would probably be a safer bet.
