I plan on using an eight string guitar with my Kemper tuned to the low E. I also saw a bundle deal selling a DXR 10 with a DXS 12 inch sub. Do you guys think the combo of the two would make for a good combination of guitar sound. Tight low djent chugging ect... I also might want to try playing a bads through it as well. I am jnder the impression that the DXR 10 doesn't ha E the low frequency response to handle 8 string guitar and bass on its own. Do you guys think the DXS 12 sub will work well for me?
