★ Modified for a more vibrant and rich sound compared to the original. Based on the MOD by K company, further incorporating original MODs. The sound is truly thick and has a strong presence, responding faithfully to subtle picking nuances. A wide range of tones are possible, from clean to crunch, depending on the guitar's volume. A noiseless and wider-ranging gain knob allows for high-gain sounds with sustained notes. Rectifier diodes have been added to the clipping section, and most ceramic capacitors have been replaced with silver mica. This results in a more noiseless and fat sound. ■■9V-17V Boost Circuit■■ By switching the switch added to the left of the unit, a standard 9V battery or 9V adapter boosts the voltage to 17V inside the effector. By incorporating a new boost board inside the unit, a high dynamic range is achieved, ensuring sufficient headroom that is resistant to distortion. The sound range expands greatly, increasing sound pressure, body, and vibrancy. *Also becomes more resistant to feedback. You can switch between 9V (down) and 17V (up) using the switch. ★ A 3-WAY switch added to the far right of the unit allows you to switch between center (normal), up (same as K company) for FAT, and down for an even thicker FAT mode. This provides a resonance-like tube drive sound. ★ The second switch from the right allows for further GAIN increase. A thick, full distortion is added. ★ An ultra-high-brightness BLUE (blue) LED is used for the ON & OFF check lamp. Both 9V batteries and AC adapters are supported. ※ May end early as it is also listed on other sites. Type... Electric Guitar Manufacturer... BOSS
