LEVEL：Controls output volume. Turning it clockwise makes the volume higher.

　　BASS：Boost / cut low frequencies. It is flat at the center

BASS/FREQ：Switch the frequency point of the low frequency boost cut. 

              Frequency rises in order of 1 → 4

MID：Boost / cut mid frequencies. It is flat at the center

MID/FREQ：Adjust the boost cut frequency. Rotate left to right to increase the frequency. It is 

            continuously variable

　　TREBLE：Boost / cut High frequencies. It is flat at the center

TREBLE/FREQ：Switch the frequency point of the low frequency boost cut. 

                 Frequency rises in order of 1 → 4

　　GAIN：It can vary from 0 dB to 34 dB.

◯　Frequency point

　　BASS　1：30Hz　2：39Hz　3：52Hz　4：70Hz　　　±20dB

　　MID  260Hz～4.2KHz　±17dB

　　TREBLE  1：10KHz　2：13.5KHz　3：15KHz　4：17KHz  ±17.5dB～±21dB

◯　Foot switch

　　EQ PASS：When the LED is lit, only the controls of GAIN and LEVEL are effective with EQ OFF

MUTE：When LED is lit Output is muted. TUNER OUT signal is always output regardless of 

       MUTE ON / OFF

The input signal is always output regardless of the MUTE switch. 

Outputting through buffere

　　　Since it is internally connected in parallel, both inputs and outputs are 

　　　possible. Because it is only connected in parallel, please be careful with 

　　　voltage management. It can be used to supply power to effectors such as 

　　　UII.

　　　Always use 9V center negative adapter. Because the consumption 

　　　current is　230mA, which is very high, we highly recommend 

　　　using a switched mode adapter with over 500mA available. 

　　 PB12DC9-2.1 from CAJ PSA-100 from BOSS is supported as well. Please 

     do not use transformerless adapter.
