Utilising light sensor technology, there are no clunky pops, no irritating scratching sounds, and no pots to wear out. Machined from solid billet aluminium, the heavy-duty housing will provide long life, on and off the road.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eRather than utilising simple band-pass or low-pass filters, the Killer Wail’s faithful emulation uses a specially-designed filter.
