The speaker configuration right now is a 4x10 with jensen alnicos, but soon i should be getting the 1x12 matching cab with a eminence/two rock speaker. its a 100 watt speaker so it should be good. its pretty simple, although you can dial in super complex tones, its easy to get any good sound. the artist and sig are much much closer to each other now than when they first made them. they use the same parts, but they only do a few extra things for the sig. the reverb is super lush, like a fender reverb, but clearer is how i can think of it. it goes from very subtle to super surf style. just need to set it carefully with the gain controll or else it will really echo! i think im going to get a 4x10 cab with tone tubbies, and sell my mesa combo with the jensens,if anyone wants it,ill let it go for a grand. but i think the 1x12 and a 4x10 will rock, and mabee a sig cab 2x12.purely awsome!
