Microphone Holder for Guitar Cabinets. Features: The spring-loaded clamping arm makes the clamp suitable for almost any type of cabinet and securely fastens to the side or top of a cabinet or combo amplifier. Thanks to its adjustable edge grip, the clamp can be adjusted to fit snugly onto recessed edges. The rigid boom is finely adjustable in both boom angle and microphone depth – this ensures a far more precise and secure mic placement as opposed to using a gooseneck-based clamping system or conventional mic stand. Material: aluminium. Clamping width: 300 - 400 mm. Extension length: 250 mm. Threaded connector: 3/8''. Weight: 0,6 kg.
