The SP25B-TP Acoustic Bass Microphone with Tail Piece Mount from AMT is a professional-quality condenser microphone designed for use with an acoustic bass. The mic has a durable and lightweight aluminum construction and a positionable flex arm for precise positioning. The attachment mechanism is designed to attach to the tail piece of a bass, allowing you to put the instrument back in its case without having to remove the mic.
Its cardioid polar pattern is designed to reject surrounding noises and to provide the most gain before feedback. The mic's disconnect cable technology lets you easily detach the cable for convenient setup and breakdown. The included "Super Preamp" features 2 XLR outputs, a ground-lift switch, 9V battery or AC power (with optional power supply), and 1/4" phone line output with volume control.
