\"mmm-mix-panel\"<\/a>Mattson VC Mixer<\/p>\n

Taking stock of all my VCA modules, I realized that while I had at least two of each type, I had built only one of George Mattson’s VC mixers.\u00a0 This is a relatively easy DIY project.\u00a0 All it takes is an assembled and tested VC Mixer board and a wiring kit, available from the Mattson Mini Modular store.\u00a0 Part numbers VCM1-B, and WK-14B.\u00a0 I had already designed the panel for the first one, so I simply ordered another from Front Panel Express<\/a>.\u00a0 (The black anodizing didn’t match the other panel, but I’ve come to expect that.)\u00a0 Add panel jacks, pots and knobs.\u00a0 Wiring is simple with the WK-14B wiring kit.<\/p>\n

Here is how the two of them look, side b side.\u00a0 The earlier one is to the left.<\/p>\n

This time I fabricated a simpler bracket from aluminum stock obtained from the hardware store.<\/p>\n
