The FET-72 is Locomotive Audio's take on the most legendary tube preamp of all time, the Telefunken® V72®. The FET-72 takes the classic V72-style tube circuit and puts a solid-state spin on it. By using JFETs instead of vacuum tubes, this module will give you access to the familiar German module sound while giving you plenty of options and flexibility. When set to “Classic” mode (switches set to NFB and Pentode), the FET-72 sounds most like its vintage inspiration, boasting a big, thick low end and smooth top without sounding dark. By removing negative feedback (switch set to NO NFB), the frequency response will be rounded off, making the low end less pronounced. Set to Triode mode, the high-frequency response will drop subtly, and there will be a smoother transition from clean to distorted when using your Colour Palette’s Drive control. Pentode mode is much more aggressive in nature. The 4-position “HI CUT” (low pass filter) gives you flexibility when driving the module for a harmonic/thickening effect. Using one of the low pass filters will make the naturally brightened result of added harmonic distortion less pronounced, allowing the user to truly shape their sound to taste. Features Triode or Pentode mode Negative Feedback (NFB) or No Negative Feedback (NO NFB) Output transformer offers depth and weight to the audio Jumpered 4-position low pass filter (Off, 18kHz, 12kHz, 6kHz) Compatible with the Colour format The FET-72 comes fully assembled and tested by Locomotive Audio. It is not sold as a DIY kit. Note: Changing switch positions can introduce pops and clicks. It is advised to reduce monitoring volume when switching to protect your ears and your monitors from damage. *The FET-72 is not made or designed by Telefunken or TAB-Funkenwerk.
