Is there a schematic floating around for this?  All of the relevant links for anything like this over at GEO are dead, and I would really like to make this my next project if possible. I suppose a schematic for the vintage MXR 10-band unit would suffice if someone happens to have that. Thanks

Bueller? ... Bueller? ...

I clued in and found what I was looking for - guess where?

Where?  (And is the 6-Band Schematic there too?  :oops: )
