Please note that these precautions are listed for all products.) 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------ Versatile Tone Adjustment: The GK-20 effect pedal offers a wide range of tonal variations, from clean boost to singing overdrive. It can be as a pre-drive gain boost, post-drive solo volume boost, or main drive tone, meeting the needs of various musical styles. Precise Control Knobs: Equipped with four control knobs. The VOL knob operates independently of the GAIN control and provides a clean boost of up to +30dB. The GAIN knob adjusts the pre-gain stage, allowing for precise control of the amount of clean sound (counterclockwise) and drive saturation (clockwise) without affecting the pedal's total output. The TREBLE and BASS knobs are 15dB active EQs that adjust the high and low frequencies, respectively. Recommended Tone Settings: We provide recommended tone settings such as "Biting Blues" and "Electric Rock" to help users quickly find the right tone. Even beginners can easily get started. Standard power supply compatibility: Requires a center-negative 9V DC power supply (current consumption 50mA). Compatible with common power adapters, ensuring stable operation. Compact and highly portable design: The product measures 11.2 x 6.4 x 3.4 cm and weighs only 0.23 kg, making it convenient to carry during live performances or practice sessions.
