This is not "natural voice with minimal coloration". I bought this pedal thinking it will linearly boost the signal like GE-7 or TC Rush. Wanted something with better switch than TC and better knobs than GE-7. But this pedal, even it its NAT mode cuts the low frequencies (I tested it with REW Software, not just by ear). Altough its not so noticable by ear I feel like BOSS should tell people in their marketing what are they buying. This is not "natural voice with minimal coloration" they clearly have high pass filter in signal path when pedal is engaged.
