Always. Synthy fuzz, fuzzy fuzzface fuzz, octave down fuzz, overdrives, envelopes, they all go through the VT because it makes em sound better. drive 10 o'clock, character 9-10, trebel & bass 1, mids 2 o'clock, vol. 9.
The VT adds a lot of texture to smooth sounding fuzzes. It makes the bass setting on my Pigtronix Disnortion sound grittier and more defined. It actually works best before my Subdecay Flying Tomato, though.
