YES and NO!
SInce you asked, I went back and took another look at the build doc. The information I wrote there is correct. If you mount a component (or diode pair, for example) between the A and C pads and mount another between the B and D pads, you can have 8 different selections available if you use a standard On-ON DPDT switch as shown.
But, I know that we can use a three position DPDT ON-ON-ON switch to give us another signal path. If you mount an additional component between A and B, (it will require stacking) you can gain an additional 4 options with the ROTOTONE DELUXE.
Therefore, in truth, you can actually use the ROTOTONE DELUXE with the proper DPDT switch to provide TWELVE (12) switching options.
Thanks for correcting me.
