The AKG C451 B Small-Diaphragm Condenser Microphone is perfect for drums, percussion, acoustic guitar and strings. Best known as the 'go to' microphone for acoustic guitars. The C451 B sits perfectly in the mix. The C451 B is a small-diaphragm condenser microphone with the identical acoustical behavior of its predecessor, the legendary C451 EB + CK1 capsule, which was a bestseller right from the start in 1969. With its airy sound, high overload limit and improved engineering details, the C451 B continues the success story of this legend. The roadworthy design around the handcrafted capsule and the low-noise preamp electronics ensure impressive results even under very harsh conditions.
