This is the new 2020 version of the Amp & Tone Controller, featuring a new transistor filter design and new skinnier 10hp panel! 

The Amp & Tone controller is a VCA paired with a sallen key filter that closes to silence, allowing use in sort of east coast and west coast type contexts!  The VCA features an exponential CV input that's normalled to the filter cutoff, along with a linear input.  The Filter has a sort of korg ms-20 like sound to it and can be unstable and screamy with higher resonance, but can be tamed some if the input gain is turned down.  Add a nice oscillator like the foundation oscillator and it's a complete voice!  Per Verbos:

"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."
