Honestly, I'd rather try a different company's clone. This ones not bad by any means, but it doesnt give you much of a volume boost. It seems like the more you crank the volume the more it becomes compressed.
I bought mine off ebay, so I didnt pay what he is asking. But for what I use it for (slide) it was worth it. I'd look around a bit at some of the other builders clones though and just take it all in.
The switches on this one do make it quite versatile though. You can taylor it to fit different guitars, its kinda nice.
