No. Distortion must be produced first and then fed into the T4S/T8S as a clean, non-clipping signal. To achieve distortion, the guitarist can use a few methods:Inline devices: One popular method would be to use any of the effects pedals on the market or use a DSP-based amplifier modeller that models the tone produced by amplifier tubes, guitar transducers and guitar amplifier speaker cabinetsMiking a guitar amplifier: Another method would be to use a guitar amplifier and mic the speaker as closely as possible. The trick here is to run the amplifier at the lowest level at which the correct tone is attainable but does not diminish the benefits of the ToneMatch setting. Louder amplifiers can be located and miked offstage. Miking small, low-watt amplifiers is a better technique for this methodUse a loading device: Some electric guitarists may prefer to use their amplifier’s output as an input signal into the power stand. Before doing this, they must use a load device, such as a “Plate Soak” or a “Hot Plate” to give a line-level output suitable for the input stage of the T4S/T8SUse the “line output” of a guitar amplifier: Some amplifiers have this option and it may be suitable for some guitarists. The only suggestion here is to turn the volume of the amplifier down so only the ToneMatch setting is heardRefer to the Bose website and Portable PA Community at www.Bose.com/musicians for more information on interfacing instruments with the ToneMatch mixers.
