It has both a Celestion Vintage 30 and a Celestion Black Shadow C90 which compliment each other perfectly. Each speaker is completely isolated with the V30 being a closed back and the C90 being an open back. The blend of both brings a great amount of depth not found in most cabs. It is also able to be ran in stereo which is a nice added bonus. Solid birch construction and it's pretty compact and portable.
