The THUNDER BOX by Lastgasp Art Laboratories, also known as the Donsharizer, is an effect pedal designed to produce the "Donshari" sound. The term "Donshari" originates from Japanese slang, representing a combination of "don," signifying a low sound, and "shari," representing a high sound. The pedal selectively boosts only low and high frequencies, allowing for powerful enhancement of the sound without passing unwanted frequencies through the circuit. Key Features: \- Controls: The pedal features two main controls, "level" and "donshari." The "level" control manages the overall output level when the effect is engaged, while the "donshari" control adjusts the treble and bass boost, enabling users to achieve powerful sounds with a single control. \- Size and Weight: The dimensions of the THUNDER BOX are 70mm (L) x 115mm (W) x 55mm (H), with a weight of 280g. \- Jacks and Switches: It includes input and output jacks, as well as an on/off switch. \- Power Options: The pedal can be powered by a 006P battery or an AC adapter (DC9V "barrel" type tip negative). Use Cases: \- Electric Guitarists: Recommended for electric guitarists seeking to achieve the distinctive "Donshari" sound. \- Musicians and Noisicans: Suitable for musicians or noisicans using a contact microphone. The THUNDER BOX Donsharizer is designed to offer a straightforward approach to boosting treble and bass frequencies, avoiding the influence of complex equalizers found in other effect units. This makes it an ideal choice for musicians looking to achieve a specific sound without unwanted alterations.
