■ Effector for guitar
■ Compressor
■ Control
・ VOL: Adjusts the volume.
・ BLEND: Adjusts the balance between the clean signal and the compressor.
・ SENS: Adjusts the ease with which the compressor is applied. The lower it is, the easier it is to take.
・ GAIN: Adjusts the boost level of the signal.

● Trim pot (when the housing is turned inside out and the foot switch is placed on the front side, in order from the left)
-LDR Adjust: A trim pot connected in parallel with the LDR. Turn clockwise to increase the adjustment range of the GAIN control. If set high, distortion and clipping may occur depending on the SENS setting.

-Post: The volume of the compressor may be lower than the input level depending on the settings. This trim pot allows you to readjust the gain to match the headroom of your amp or pedal.

-Decay: Adjusts the decay time of the LED in the LDR when the input level drops, and sets the release time. The maximum clockwise setting makes the dynamics smoother, and the minimum counterclockwise setting emphasizes compression. Adjust according to your playing and tone preferences.
■ Power supply: 9VDC center minus (batteries cannot be used)
