Additionally, their products faithfully reproduce the circuitry, components and overall legacy of these vintage circuits. In other words, they are making it possible for any musician to own modern versions of the best equipment ever invented. Now that we are all on the same page why don’t we look at some of their products?

WA-84 Small-Diaphragm Condenser

When designing the WA-84, Warm chose to go the extra mile and tackle a more boutique design known for its crystal clear, yet smooth, LARGE sound. Most importantly, it offers unique tone in a small size, the WA-84 uses a heavy Nickel CineMag transformer in its signal path to warm up and ENLARGE sound sources. Small diaphragm condenser microphones have widely moved to transformer-less technology in recent years for ease of design and a lower-cost manufacturing process.

WA87 FET Large Diaphragm Condenser

The classic ‘87 is arguably the most widely-used large diaphragm condenser microphone in pop recording history. Rather than base our WA-87 circuit on current incarnations of this mic, we decided to closely follow the early circuit designs that date back nearly half a century. As is true with many classic microphones, engineers who have worked with different versions of these microphones often prefer the warmer, more forgiving nature of the earlier commercially available models. The desire to re-introduce the warm tone of this classic mic at an affordable price to an all-new generation of recording artists was the inspiration behind the WA-87.
