This model is inspired by FuzzHugger Doom Bloom, which at the same time is an improved design of the Algal Bloom. This board delivers some very unique, harmonically rich, wide-range tones that will appeal to any lover of fuzz!
Six interactive controls open a portal into a world of highly textured harmonically rich fuzz tones with a wide range that goes from flourishing, striking blasts to muddle super-fuzz, conjuring up all sorts of electric fuzzing in between. Doom Boom comes with a vast gain stage without losing one of its most notable aspects: a precise note definition and texture.
Now, let’s check some of the controls that make this pedal work the way it does:
Bloom control creates fuzz+gain+definition. It increases gain and note separation. It holds together pretty nicely when cranked, allowing it to hold up well with lower tuning.
Head control is a headroom. If you turn it right, the headroom goes up and increases the loudness, massiveness, and openness of the pedal, making it less clipped in the process.
Body shifts a considerable amount of lows in/out of your sound, leaving highs intact. Body also gives you control over fuzziness.
High controls highs (unsurprisingly), but it works separately from Body. So, you can set your lows and fuzziness where you want and then adjust your highs independently.
Bias biases the first transistor gain stage controlled by the Bloom knob, allowing to have an additional boost and character control. This is what we are talking about when we say Massive Boosting Power!
