Has anyone ever used/heard of one of these? It's not even listed on Guyatone's web site, so it's either really new or really old. It's part of the flip series so it has a tube in it. I'm just wondering if it's any good or if I should just get the ART Levelar or DBX 160a, both of which seem to be the most popular among TB'ers. I'm kind of new to the world of bass compression.
