Audix Cab Grabber

This cab micing device works well with standard cabs and combos. However, if you got a combo where the speaker is mounted a bit off-set you may find it tricky to get the mic in exactly the spot you want it. The non-flexible neck of the mic-holder makes precise positioning hard. In my opinion there are more versatile and less expensive alternatives.

The spring mechanism is great so it can hold itself on the cab pretty nice, but setting up the angle of the mic gets a bit tricky cuz of the design, you can't get a good tight setup without using some sort of clamp to help. I used it at a live gig once and mounted it on the side of the cab, and halfway through the show, the arm decided to just let loose and dropped the mic position to where it wasnt facing the speaker at all.

If possible i'd recommend to mount it on top of a cab to reduce that risk, but other than that, just stick to a regular mic stand.
