I love the SL-OD. Especially since it's configured withe double the OD. My one beef whether it be the real SLO, Slodano or Salvado, is I never care for the crunch side of things. So, why not build a Dual OD module? That IS the answer. The same thing goes for the XTC. I don't care for the Red channel, the Green channel is good, not great. Why not build in two Blue channels? Again, it's the right answer (for me). The Voxless just adds a nice touch of chimey cleans and mid drive crunch. It's been a nice couple evenings with the rig.
