The Elvis Mic

• because of its iconic design, the 55 Unidyne series is inextricably linked with the emerging rock 'n' roll of the 1950s
• Model 55SH Series II based on the 1951 'Small Unidyne' Model 55S, which is smaller in size than the former Model 55
• the capsule of the Series II is the same that used in the Shure SM48
• wide cardioid polar pattern
• uneven frequency response with a wide band reduction in the lower midrange and a pronounced presence peak at 7 kHz due to the housing
• fairly prone to feedback and hiss
• items for hire are the current 55SH Series II and an old Model 55 'Fatboy' (only as a prop)
• manufacturing period: Model 55SH Series II: since 1989;
  Model 55: 1947-1951

Favourite applications: Nostalgia microphone for stage, prop for films and video clips. The 55SH Series II is rarely used in recording studios because of its mediocre sound characteristics
