Prince with immediate spring clip. Quick and reliable attachment above or below the tom. The gooseneck is equipped with a 3/8" thread with a 5/8" adapter on which you can mount an SM57 holder, for example. It comes with a clip for a small diameter microphone. The gooseneck is firm, it holds the imposed position well, which allows adapting the sound capture to your convenience. It is also adjustable in length with a very effective and secure butterfly nut clamp. I bought this holder to install an SM57 in a cajon. I made an additional holder to use the immediate clip system. In the manufacturer's place, I would have lengthened the gooseneck by 2 or 3 cm to provide more comfort when using bulkier microphones without compromising its very good rigidity.
