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 preserving the important nuances of the OD-3, the internal basic 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 when the switch is down, and the HP function works when the switch is up, 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 on the top of the unit switches to the knobs on the side of the unit. The left knob (GAIN2) and the right knob (LEVEL2) can be used to boost the sound, such as during solos. Practical use is possible, such as setting different settings for backing and lead and switching instantly. 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. Both 9V batteries and AC adapters are supported. ※We are also listing on other sites, so it may end early. Type...Electric Guitar Manufacturer...BOSS
