Due to the fact of the white leds I use being backordered, I have found a source for diffuse white leds. I have to say these do not magically fix the diffusion of the buttons. They only add marginally to the effect. I am now also including a Mk2a knob along with the Mk2 type. I hope to have a semi large quantity of at least blue kits ready to go out around April 8th.
