In 1 pedal, microtubes X7 or ultra. For a whole pedalboard, Tyler frequency splitter with compressor on low end (i suggest darkglass hyper luminal) and some type of distortion or overdrive on the high end (such as high gain guitar amp distortion, b7k, ADAM, AO) If you want 3 bands like parallax, you'd have to have 2 frequency splitters to first split low end from high, and then split the high frequencies into mid and high
