After all the research, reviews, clips, vids and consultation, I finally ordered a WGS Reaper 30 for my Nolatone (open back) Rotten Johnny combo.
I'm hoping for a little more oomph...some more top & bottom vs. the Heritage G12M I've been using.
Not that I dislike the Greenback...just want to try something different. More to come after install.

Any other players using stuff from Warehouse Guitar Speakers?
