The TF47 is a new design based on the “German” sound, drawing inspiration from the historic U47 and M49. With a deep low end and a forward midrange, the TF47 is excellent for adding depth and presence to any source. These characteristics make it especially ideal for recording vocals, guitar amps, and drums.

Circuit Design

At the heart of the TF47 is an all-brass K47-style capsule, new old stock 5840W vacuum tube, and custom-made historically accurate BV8 transformer (as found in the U47). These components deliver a warm and punchy sound reminiscent of the U47 with a pleasant top end articulation that sits perfect in a mix.
