Critic Reviews

Keeley Engineering Super Phat Mod & Hooke Reverb

guitar.com

The Keeley Super Phat Mod overdrive pedal offers a sophisticated take on the classic Boss BD-2, with amp-like dynamics and a sleek, gold finish. The pedal's versatility shines with a switch between 'flat' and 'phat' modes, catering to different tonal preferences. While it delivers excellent touch sensitivity and smooth distortion, the 'phat' mode's added bottom end might not suit every situation. Nonetheless, its ability to mimic a high-gain amplifier channel is impressive. Overall, it's a well-judged, classy addition to any pedalboard, providing dynamic flexibility and a high-quality overdrive experience.
