I purchased this used about three months ago. As the reviews said, it's a very rich-sounding and excellent effector, but I've decided to sell it due to the needs of my band's sound. I'd like to pass it on to someone who will use it more. I will consider some price negotiation separately. *Please refrain from purchasing if you are overly sensitive. Only those who understand that this is a used item, please. *The following is a product overview. The DJ1 is the first bass effector from the high-end Japanese effector brand VEMURAM. After collaborations with veteran musicians such as Miles Davis and Sting, it is a handmade overdrive/distortion pedal for bass, born after a long joint development (about 6 years) with American bassist DARRYL JONES, who is currently active as the bassist for the Rolling Stones. It features a brass body with seven knobs and two footswitches. Separate from the distortion ON/OFF, the booster can be turned ON/OFF individually. You can create a clean sound with the CLEAN knob and a drive sound with the DRIVE knob, and mix the two sounds with the MIX knob. It is equipped with a 3-band EQ including the MID knob on the back of the body, and a SAT knob to adjust the saturation. Furthermore, inside the body, there is a mid-frequency switching (1Khz/600hz) switch, an OUT2 output ground/lift DIP switch, and an output adjustment (12db to -33db) knob for OUT2 output, allowing you to fine-tune your sound.
