http://www.pedalgeek.com/cgi-bin/new_shop.cgi?command=link--dsd It's a light overdrive or clean-to-dirty boost, with optional compression. I just received it today, so I can't properly review it yet; and I won't have time to record clips today, but I will do my damnedest to put some up by tomorrow night. But my first impression of it is so very positive that I felt compelled to post about it already. Good stuff: very low noise natural-sounding drive NO LOSS OF LOW END very articulate and dynamic The tone knob just affects the high end, so the lows are the same at all points on the tone knob. With the tone at minimum it rounds the sharp edge off the drive, for a warmer tone; with the tone at max it enhances the sharp edge, for more nasty bite; and with tone at noon it's a nice general-purpose drive voice. The compression is surprisingly good! I'll have to get more in depth about that in my proper review, but I have to say my initial thoughts about the compression are quite positive. The "soft" setting is a low ratio, and the ""hard" setting is a high ratio. It's a 3-position switch; the middle position bypasses the compression. The one I have is an older model in the BB (Barber, Diamond, BBE) size box; the new model is in the smaller MXR-size box. Anyway, I'm super excited about it, and of course I'll post more about it later--along with clips.
