One Control Minimal Series Black Loop with BJF Buffer (OC-M-BL2)

One Control Minimal Series Black Loop with BJF Buffer is an easy-to-use loop switcher that has the BJF Buffer-which can be bypassed on the input-and 2 DC outs to power other effects. It can be used as a loop switcher for true bypass or buffer bypass while supplying power to the effects connected to Loop-1 and Loop-2.

The switching of each effect loop is standard true bypass style, and you can use it in the same way as the buffer bypass by turning on/off the buffer on the input.

The Black Loop is effective when connecting multiple effects to one effect loop, or using old effects that may load or degrade the signal when bypassed.

By connecting to the tuner from one effect loop SEND, it can be used as a mute switch and tuner out.
By connecting from the SEND of one effect loop to another amplifier, it can also be used as a switch to switch between multiple amplifiers.
LOOP1: Turn on the LOOP on the right side.
LOOP 2: Turn on the LOOP on the left.

If the BJF Buffer in the input part is set to OFF, it can also be operated without power (the LEDs do not light up.)


This amazing circuit is installed in many of the switching products from One Control. It is one of the most natural-sounding buffer circuits ever created that changes the image people have from using old buffer circuits that degraded the tone of their instruments.


  • Precise Unity Gain setting to 1
  • Input impedance will not change the tone
  • Will not make output signal too strong
  • Ultra-low noise output
  • When the input is overloaded, will not degrade the output tone.

Created at the request of many of the world’s greatest guitarists by Björn Juhl­-one of the greatest amp and effects designers in the world-the BJF Buffer is the answer to keeping your tone pristine in all sorts of signal chains, from the stage to the studio.

When more effects are connected later, the more critical a buffer is. This is the function of incorporating the BJF Buffer into the input. By turning on the BJF Buffer, you can stabilize the overall tone to a warm and natural sound with less signal loss and degradation.

Black Loop with BJF Buffer works with a center-negative DC9V adapter. The capacity of the current supplied by DC Out depends on the adapter you are using. Batteries cannot be used.
