With a deep low end and a forward midrange, the TF47 delivers a warm and punchy sound reminiscent of the U47 and M49.



The TF47 is a modern 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. 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, as well as a pleasant top end articulation that sits perfectly in the mix with a certain authority and weight.
