This is a new version of our old favorite. We have taken the functions of the Amplitude & Tone Controller into a smaller 10HP package and shortened the name to what we have always called it. For those who don’t know, the module is a Sallen-Key lowpass filter followed by a VCA. The signal path is still all discrete, but now the filter is also made from transistors. The sound shaping possibilities remain, including a balance of distortion from the input stage or the filter as well as simultaneous linear and exponential control of the VCA.
