I am building a Mojo 100w Super Lead Kit, but I am following the Metro guide for the most part. This a 4 input Marshall. Is this meant to be a hi-lo set up for each of the input pairs. Each pair goes into two 68k's then to the grids. I get 68k on the top input and 33k on the lower of each pair and I read from the tip of the jack to the grid.
