As I was reading here about customizing it, I couldent resist and screwed the hole thing apart. Unfortunatly, there is no way to take the Roland and BPM text away in the bulls eye, because its like a lens made from 2 layers, one laser engraved, and somehow weldet together. Its like one piece, have a look:
However, in the coming weeks, I will customize some other things which you might be interested.
Stay tuned
