This is a setting saver for BOSS compact pedals. * It's designed so the knobs are completely hidden even if stepped on, providing peace of mind! * It won't fall off even if turned upside down! * Prevents problems like broken or bent knobs! * Prevents issues like "I feel like the settings are slightly off!" * All items are inspected! For 4-knob models (excluding the X series). Please feel free to contact us if you'd like to know if this pedal is compatible, or if you'd like us to make one specifically for your pedal. * These are made by an amateur using a 3D printer.
