The M T2D dual triode distortion is a Nutube-based distortion module for the Eurorack format, offering two independent channels which can be patched separately for parallel processing, stereo, or multiple sources, or used in series for more complex distortion of a single source (or simply extreme distortion settings).

Spectral tilt filters before each triode stage alternately boost or cut high and low frequencies for different harmonic emphasis. These filters also affect the feedback loops, and can interact in very interesting ways with high feedback settings. The individual tube bias controls can also have a strong influence in combination with high feedback levels, in addition to more subtle shaping of the distortion when feedback levels are low.

Independent control of input level, tube bias, feedback level, and dry/wet mix is available for each channel, with CV inputs for the bias and mix controls. The CV inputs for the mix controls also have dedicated attenuators. A global plate voltage switch offers two different character options, for either smoother distortion or more severe clipping.
