The Effects Bakery Suguru Big Katsu Distortion is a high-gain distortion pedal built in a mini case with three knobs: Volume, Tone and Gain. The maker describes it as delivering "crunchy and thick tones reminiscent of post-rock or shoegaze styles", with a thick character and a slight low-end roll-off1. It is a collaboration: Effects Bakery has been partnering with companies in Japan, including the food maker Suguru Foods, and the pedal takes its name from Suguru Foods' BIG KATSU snack1.
Batteries cannot be used in the Big Katsu Distortion. It runs only from a standard center-minus DC9V adapter or a pedalboard power supply output. At 2mA, the draw is low enough that it will not strain any output on a shared supply1.
Controls
The pedal keeps things to the classic three-knob layout1.
| Control | What it does |
|---|---|
| VOLUME | Adjusts the overall volume. |
| TONE | Controls the tone. |
| GAIN | Adjusts the intensity of the distortion. |
Sound and character
Delicious Audio, quoting the manufacturer, describes the Big Katsu as "a high-gain distortion delivering... crunchy and thick tones reminiscent of post-rock or shoegaze styles", with a thick tone that has a slight low-end roll-off1. Players drawn to those styles, or comparing it against overdrive and fuzz options on their board, will find it sits firmly on the distortion side of the gain range.
