The Waveform 1U LPG/VCA module is an 10HP passive powerhouse. By switching out one component this can be either a Low Pass Gate or Voltage Controlled Amplifier (actually, since it's passive, it's an attenuator NOT an amplifier), and the faceplate text can be Sharpied over to show if it's a VCA or LPG. These are pretty easy to build, and the instructions on how to build this can be found on our Build Guide page. Faceplate is black with silver.
All Waveform 1U modules use the Intellijel size format.
