The Yellow King Henry is a phaser pedal from Rotosound King Henry, the British string maker's entry into effects. Guitar Interactive Magazine's Jonathan Graham described it as sweeping "through the entire audio range from shimmery to vibrant, twisting to resonant guitar," placing it among the wider-ranging phase effects rather than a single-speed design1.
What it does
The pedal's headline control is PEAK, which Graham described as "a control for the wider ranging of phase effects"1. In practice that means the PEAK knob shapes how far and how broadly the phase sweep reaches across the frequency range, from a subtle shimmer to a deeper, more resonant twist.
Background
