There goes the distinction between the older circuit design (green board, 1995-2000) and the new layout (cream colored, 2001 to present). The photo below is a new Series III Blues Junior, but with a green, transparent circuit board. The components and layout are identical to all the cream-colored boards. You can see the Series III faceplate at the top.
This will doubtless cause some confusion among “old green” and “new green” owners, but as long as it was built after 2000, the existing cream board mods work properly.
