I saw that Sweetwater had these for $40 (looked like a close out sale). Couldn't really find any information and very few video reviews most of which were bluesy, so I took a chance. It doesn't have much of an volume boost at all, and the "tone" knob only adds or takes away high end, but it has a very pleasing and warm tone to it, seems like a low mid bump with a very subtle bass rolloff, and the compression on it is also subtle but very pleasing to play. As a "clean" boost, it fails since gain at 0 provides very little compression, and volume at 10 is for all intents and purposes unity gain. However, I have been enjoying it as a drive for my dual rec, since it sweetens up the high end and let's the mids bloom/glow more. I found myself lowering the gain between 11-12o'clock when I normally have it around the 1o'clock "sweet spot" everyone seems to run. I don't have a maxon 808 to compare it to, but it makes the ts9 sound harsh (when running the ts9 at gain 9'oclock, volume 12o'clock). Just though I would post this in case anyone is searching for information about one regarding heavier gain settings, or wants to grab another overdrive cheap.
