Blast From The Past

The WA-47 is an all vacuum tube, large diaphragm, transformer balanced, multi-pattern (9), large condenser microphone, based on the classic 47 that has been used on countless hit records for the last 50+ years. The WA-47 is designed for pro studio, home studio, live, and broadcast applications and sounds great on vocals, acoustic/electric guitars, acoustic/electric bass, drums, piano, strings, brass/woodwind instruments, and an array of other sources. The classic 47 became extremely popular in the 1960s and is now considered one of the greatest microphones ever made. The classic 47 is still widely used today in professional recording studios but have become extremely rare and expensive to acquire.
