The One Control Minimal Series Black Loop with BJF Buffer is a 2-loop switcher equipped with an ON/OFF BJF Buffer in the input section and two DC Outs. It can be used as a true bypass or buffered bypass loop switcher while supplying power to the effects connected to Loop1 and Loop2. Switching each effect loop uses a standard true bypass style, and you can use it like a buffered bypass by turning the input buffer ON/OFF. It is also effective when connecting multiple effects to one effect loop or when using older effects. * By connecting the SEND of one effect loop to a tuner, it can be used as a mute switch and tuner out. * By connecting the SEND of one effect loop to a different amplifier, it can also be used as a switch to switch between multiple amplifiers. LOOP1: Turns ON the right LOOP. LOOP2: Turns ON the left LOOP. If the BJF Buffer in the input section is set to OFF, it can also be operated without supplying power (the LED will not light up.)
