※ This is a listing for a knob setting guard. The effector unit itself is not included. This is a homemade knob guard designed with CAD software and 3D printed. It was made to not detract from the appearance as much as possible. It has been updated several times and is now stable, so please use it if you need one. ※ As shown in the side view image, the height of the guard parts is made to match the height of the pedal, but if it is to be used with an effector with a high knob ceiling position, please contact us in advance. We will modify and manufacture it. <Specifications> Made to fit models with an operation panel (base) on the top. Please note that we have not confirmed implementation on all models. The frame part is the same size as the main unit. The screws are designed so that the heads do not protrude, so there is no visual discomfort. <Product Contents> Knob guard x1 Replacement screws x2 You can use the screws that came with the effector as they are, but we also include replacement screws. <How to Use> Remove the screws and washers on the side of the stomp part, set the knob guard on the main unit, and re-screw it. When attaching, the order of stomp part - washer - knob guard - screw is preferable. If the screws are not tightened tightly but are slightly loose, you can lift the knob guard as shown in images 4 and 5, and change the settings when necessary. If you have any questions, please feel free to ask. Colors other than black are also possible, depending on the materials we have.
