Features a dual-stage overdrive circuit. Characterized by beautiful overtones, a thick low end, and sustained sustain. An all-around overdrive that can be used from chord cutting and riffs to solos. While retaining the important nuances of the OD-3, the basic internal lines have been changed to high-quality parts, resulting in clearer sound and lower noise. ★The 2-way switch on the left side of the unit allows you to switch the HP filter (low cut). The same as normal below the switch, and the HP function works above the switch, moderately cutting the low frequencies unique to the OD-3. ★The 3-way toggle switch on the right side of the unit switches the clipping circuit. The original silicon high-compression (S) mode is on the switch up, LED TUBE DRIVE (M mode) is on the switch down, and BOOSTER mode is in the center of the switch. ■■Twin Drive Mode■■ The foot switch added to the top of the unit switches to the knobs on the side of the unit. The left knob is (GAIN2), and the right is (LEVEL2), allowing you to boost the sound significantly during solos. It is possible to set different settings for backing and lead and switch instantly, making it practical to use. The ON-OFF check lamp is ultra-high-brightness BLUE (blue) during normal operation, and the check lamp switches to ultra-high-brightness RED (red) in BOOST mode. Compatible with both 9V batteries and AC adapters. ※We are also listing on other sites, so it may end early. Type...Electric Guitar Manufacturer...BOSS
