A pure modern classic, the 4400a features four polar patterns, a vintage-style brass capsule, two bass cuts and two pads, and the most adaptable shock mount around.
Much like a few particular well-known classic European condensers, the 4400a is a true "all-rounder". You can put it up on just about anything and it'll sound great. Unfortunately for many studio owners, those "classic condensers" are often not what they used to be. Capsule designs change over time, capacitors dry out, metal switches are replaced with plastic buttons and LEDs, and the mics that were once so versatile are now mere shadows of their former selves.
Given the practically cult status of these vintage mics, SE saw an opportunity, and from that arose the 4400a. Now these classics are obtainable - hand-made brass capsule, four-polar-pattern-versatility and all. And like the classics, the 4400a sounds great on everything. Vocals, guitars, toms, overheads, classical pianos, strings, you name it. Its tonal versatility is incredible at this price point.
