This pedal has undergone a number of design revisions, but I own and use the one pictured in the image (Black box design, black knobs, white rectangle logo). This is a stellar overdrive pedal with a host of adjustments from internal trim pots to a push/pull bass boost knob. The title of this review is the best descriptor. It's easy to quickly get a solid OD sound, although I prefer keeping the gain around 50% or less. The push/pull is handy, but I do find that I often bump this knob when it's pulled out. The flavor is more of a TS808 inspired tone, only a little more transparent and with more "umph". I've seen these used for a great price and would absolutely recommend it. It's a great "boutique" spin on a classic OD for less than boutique cost. Not to mention, David Barber is great at customer response.
