Warm Audio WA-47jr

At Palen Music Center, we are thrilled to offer the Warm Audio WA-47jr, a FET transformerless powerhouse that brings the legendary "47" sound to your studio without the vintage price tag. This microphone is built around a custom K47-style capsule reproduction—the same high-end component found in Warm Audio’s flagship tube model. By utilizing a fully discrete signal path featuring premium Toshiba FETs, Wima film capacitors, and Panasonic electrolytic capacitors, the WA-47jr delivers a boutique tonal signature that is both classic and remarkably clean. Whether you are tracking intimate vocals, aggressive electric guitars, or detailed orchestral strings, this versatile workhorse is designed to punch well above its weight class in any professional or home studio environment.
