Ive never herd of the brand but its Jade sound systems PRO.15 Ive looked it up but nuthin came up. I just found where the name was written today.(im not stupid they just put it in the stupidest place) I'll probably just forget this one and buy a new one anyway. All its got is gain, tube drive(knob is broken), bass, mid, treble, and master volume. Headfone jack and ftswith jack and hi and low inputs.
