I'm not sure what you mean by blue. I have both the green and the clear (blue?). The clear has the noise suppressor switch while the green does not. BTW, both are broken. Any opinions on where to send for repair. Would really like to get them up and running. I was thinking of contacting quad Bob but he seems to be very busy. Phil
The color of the VU meters is simply a function of the color of a piece of plastic that covers the face of each bulb. Find apiece of orange plastic the right size and that can take the heat of the bulbs, and you can have orange meters on your RS-858 if you like.
