Akai controllers typically have low profile recessed rotary control knobs. These can be a pain to turn and even more awkward to replace.
These rotary control knobs are typically in the 180° position. Although this type of knob is widely available, the short length of the potentiometer shaft can make finding a knob with the proper fit tough. The recessed seat for the knob will also constrain the maximum diameter for control knob selection.
The best fit we have for Akai rotary control knobs is our KZ0043 rubber grip DX control knobs
