Used EMISSARY Guitar Effects Pedal

This Walrus Audio Emissary Parallel Boost is a 2-in-1 analog guitar effects pedal designed to make lead lines stand out, add clarity to fingerpicking, and push tube amplifiers into natural breakup. It features two independent boost circuits that run in parallel, letting you use each circuit on its own or blend them together.

Description & Key Features

• Bright Circuit (Top Knob): A clean, high-headroom JFET boost that adds high-end sparkle, definition, and top-end vibrancy.
• Mid Circuit (Bottom Knob): A targeted midrange boost that injects punch and presence. It includes a 2-way toggle switch to choose between 800 Hz or 1 kHz center frequencies.
• Switching: Features true bypass with a smart soft-relay footswitch that also supports a momentary function (press and hold to temporarily engage the effect while off).
• Aesthetics: Silk-satin black finish with artwork by Adam Forster featuring an x-ray graphic.
