Unless I missed it, nobody's created one of these yet. I used to have a Barber LTD that I loved in a lot of ways, but wound up selling. Recently, though, when Barber came out with the Gain Changer, I was all over it. It's essentially four pedals in one: The LTD, LTD SR, LTD Silver (similar to the fat/flat setting on this pedal) and the UnLTD (the GC doesn't have the double drive of the actual UnLTD pedal, of course, but it gives you the same higher-gain sounds as that one). It was so nice, I had to pick up the Compact Direct Drive when that came out, and I'm pleased as punch with that one as well (Direct Drive, Direct Drive LG and Super Sport in one package). For $130 a pop, these are a great deal, IMO. I'm surprised that Barber doesn't get as much buzz as some of the pricier small-time builders because his products are every bit as good (if not more so). They sound great, they're well-made, and they're not too much money. What's not to like?
