Go get 'er Jer, it would be very cool to see one opened up just to see the differences between the Series I and II besides the faceplate and meters
I was wondering that IF someone preferred VU meters, wouldn't a set of Series 1 meters from a 400 Series 1 or 700B drop right in? As long as the bezel cut is the same, I bet they would go right in. I know you can use 700B meters in a 400 Series I (same size but flipped, you also have to flip the bezel). I think it would look friggin' tits with VU meters but that's just me
