2-in-1 parallel booster for optimal tone shaping The Walrus Audio Emissary is a 2-in-1 "parallel booster" with a completely different concept from conventional booster pedals. A two-system boost circuit design with separate "Bright (treble booster)" and "Mid (mid booster)." Not only can each be used independently, but the boost circuits of each can also be mixed in parallel for output. This operating principle, which is not found in conventional boosters, allows you to obtain an ``optimized boost sound'' that matches any guitar or equipment. By combining and outputting a parallel mix of two independent boost circuits (Bright and Mid), it is designed to provide the optimal boost sound for any guitar or equipment. With simple controls and a wide range of applications, it forms the core of your guitar sound. The Bright knob uses a high-headroom JFET boost circuit to add a premium top end to your guitar sound. This treble booster adds musical clarity and enhancement to your tone, bringing out the sound of front pickups and humbuckers. The Mid knob is a mid booster that allows you to switch the frequency range you want to focus on at 800Hz or 1kHz. The unit's fat and punchy mid-boost is exquisitely tuned to deliver a lush, musical tone. It's useful in many situations, such as adding an organic mid-range to a single-coil guitar or enhancing a solo tone. The 800Hz/1kHz switch is a simple yet professional design that maximizes effectiveness, allowing you to adjust the appropriate boost for your guitar type and the tone you're aiming for. These two controls can be used individually as a "treble booster" and a "mid booster," and can also be used to output a parallel mix of each other's boost circuits. This operating principle, which is not found in conventional boosters, allows you to create a ``booster color'' that matches the character of your guitar or tube amp. The footswitch also supports a special momentary action, which enables the effect only while you hold down the switch and turns it off the moment you release your foot. It's a simple yet unique tool for creating tone-shaping boosts perfect for any guitar.
