Masamune is a sound-crafter pedal. It forges your dry-signal, enhancing your sound before sending your signal to your amp, and/or any effects unit. The Booster adds beneficial color to your signal, and, if necessary, after you adjust the boost & drive levels, you can cut high frequencies on your Input signal with the Hi-Cut Toggle Switch. Masamune’s Kompressor does a remarkable job managing and enhancing your signal: Komp Level knob adjusts the final Output level for the Compressor, perfectly balancing your Input and Output signals. Sustain knob adjusts the compression ratio, and increases sustain. Higher sustain levels will squash your signal harder when you hit the strings and creates a longer, richer sustain. Blend knob adjusts the compressor transparency from 50% to 100%, so you can dial-in the exact amount of compressed dry-signal blend you want.
