Pedals that stack with the Greer Royal Velvet

Keep the Echolution after the Royal Velvet — the smooth, velvety fuzz stays thick and the delay's complex, modulated repeats trail behind it. — goes in the amp's FX loop (or last, into a clean amp)

Run the OB.1 Bass before the Royal Velvet to keep the low end controlled going into that smooth, velvety fuzz.
