I was looking for an alternate drive flavour to my Fulltone OCD and JAM Rattler (RAT-style distortion). I ordered the AT+, Angry Charlie, Friedman BE-OD, Bogner Ecstasy, and Catalinbread Dirty Little Secret to compare as well.
This pedal really fills a gap for me. It has more clarity and crispness than pedals like the OCD, Rattler, Angry Charlie, and AT+. They all have more "girth" (boominess/muddiness on certain settings).
The 19 and 22 modes switch between Plexi and JMP/JCM800, though I admit I don't have the experience to say how accurate the tones are. They both sound great in their own way. Frankly they sound better than the Marshall-mode on my Strymon Iridium.
I like the dual gain knobs. They behave differently in both modes and let you mix treble in with the signal (19 mode) or add low end richness (22 mode). It really shines at mid-drive to distortion — not quite high-gain metal, but plenty for hard rock.
The 3-band EQ offers good tone sculpting capabilities. Nothing extreme — they are very amp-like in behavior. The presence control can add a ton of high-end sizzle. I'm a little worried about these thin, tall knobs though.
The boost gives you a touch more growl/gain, but it's not a dramatic difference. Definitely not a lead boost.
The black and gold design is pretty, and immediately tells you what this pedal is supposed to sound like.
Overall an awesome pedal for Marshall-like tones in mid-gain territory.
