If you are only used to regular low pass filters, this one will take some time getting used to. I suggest digging some material online or video guides to make sure you understand the relationship between frequency and mix. The mix knob allow you to seamlessly glide between lowpass, notch and highness. Creates some unexpected and happy accidents. The attenuation is good. Only downside is the knobs that are too tight for my taste. The nicotine color is fitting for the time period it represents but it is of course very subjective if it is actually looking god and wether it fits your other modules in the case :)
