Know before you buy
This kit is best suited for those with intermediate soldering experience. You should be comfortable working with through-hole components and following a schematic, as the build requires precision to ensure the filter functions correctly.
The kit includes the PCB, all necessary electronic components, and your choice of panel. You will need to provide your own soldering iron, solder, and basic hand tools to complete the assembly.
The difference is purely aesthetic and structural. The metal panel offers a more traditional, industrial Eurorack look and feel, while the black panel provides a sleek, modern alternative for your rack.
Unlike a standard filter that simply cuts frequencies, a formant filter mimics the resonant characteristics of the human vocal tract. It creates vowel-like sounds and complex harmonic textures that add a distinct, organic quality to your patches.
Yes, the Motomouth is designed for the Eurorack format and uses a standard 16-pin power header. Ensure your power supply has enough current overhead to accommodate the module before installation.
