I'm comparing different "all in one" PA systems. Was recently able to demo an HK Lucas Nano 300 in a store and was quite impressed, especially for the price and weight. Downside was that it did not have any built in effects or EQ. The Stagesource series, if I understand it right the "t" models have the built in mixer and effects, while the "m" models do not, is that correct? What are the major differences between the L2 and the L3 t models? Just power or? Has anyone here played a jazz guitar through the StageSource,, if so, how did it sound? Thanks!!
