BOSS AB-2 Schematic?

[Juntaar]

Hi All,

I've tried to search this forum and google for the AB-2 schematic but haven't as yet found anything. The closest I found to something relevant was a single resistor mod for adding a DC jack to the AB-2:

Can anyone point me in the direction of a schematic?

Thanks in advance!
