The sweepable HPF from 30Hz to 400Hz allows precision crafting of the low end.\u003c\/span\u003e\u003cspan\u003eA new function is that the instrument input can be routed directly to the output stage without passing the preamp stage (the saturation circuit and HPF can still be inserted).\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eThe DI direct mode together with the vintage Class A stage gives
