Nice organic sounding overdrive pedal. Really well made. True bypass. Really nice as a dirty colored boost. Also a great mid boost. And at higher gain, a really good distortion, sort of Marshall Plexi territory. Really good for rhythm crunch.
the Snarling Dogs' original description said: "You own a classic American vintage or reissue amp setup and want more power and punch like the British amps of the late 60s, then add a Black Dog to your rig. Emulating the roar of a cranked up classic British amp driven by EL34 power tubes, you get great bottom, smooth highs, mid-range warmth, and exceptional in-your-face drive and crunch? Reminiscent of the song after which it was named."
