The unit is preset for an 8 Ohm load, but can be factory modified for 4 or 16 Ohm. You can go direct and use your speaker simultaneously if you choose by using the Thru jack, and there are also four additional unfiltered 1/4“ outputs with a separate level control. Two three-way filter switches allow you to adjust high-end response to simulate "American“, "British“, or "bright“ speaker types, and adjust low-end response to simulate closed-back 4x12, "neutral“, or open-back 2x12 speaker cab sounds.
