I bought this head a couple of years ago along with an MB200 as a backup. I ended up attaching the MB200 to my pedalboard and it's seen all of the action, as the MB800 sat in a padded bag. These heads are huge in tone and volume. I've provided a link to GK's website with the specs. The sale includes the head, the unused footswitch, and footswitch cable that still in its original plastic wrap. For Sale only, so no trade offers, please.
