Please read the profile before purchasing for a smooth transaction. This is a knob guard/setting saver for the Darkglass Microtubes B7K (v1). * It completely covers the knobs, so you can step on it with confidence! * Prevents issues like the settings slightly changing due to the shield touching them! * Prevents gear failure due to broken or damaged knobs! * No need to stick stickers on your effector when you want to record settings! You can memo multiple settings! * All items are inspected! * It fits perfectly and won't fall off! If you have any questions, such as whether this can be used with your pedal, or if you'd like me to make one for a specific pedal, please feel free to ask. * This is handmade by an amateur. I will ship after testing for proper function, but please understand that there may be individual differences. * If you do not specify a color, it will be sent randomly. The available colors are listed in my profile. Colors other than those in stock will be an additional 250 yen per color. * Discounts are available for multiple purchases, and combined shipping discounts are also available with my other products. Please feel free to contact me.
