Please read my profile before purchasing for a smooth transaction. This is a knob cover for the MXR M108 10 Band EQ Effects. I will send a black one. ・Safe because the knob is completely covered even if stepped on from above! ・Prevents problems such as knobs breaking or bending! ・Prevents problems such as feeling that the settings have changed slightly! ・All items have been inspected! ・This is made by a amateur using a 3D printer. I will test for normal operation before shipping, but please understand that there may be individual differences. ・If you do not specify a color, I will send a random one. The in-stock colors are listed in my profile. Also, colors other than those in stock will be an additional 250 yen per color. ・There are also quantity discounts and combined shipping discounts with my other products. Please feel free to contact me.
