Mission Engineering KM 212P from Petaluma, CA. It was designed to work as a FRFR cab for Kemper heads but can be used as a normal guitar cab with regular speakers. I used it for the past year with Celestion vintage 30s and it sounded great. I’m selling it unloaded. It’s very sturdy and side handles make it easy to carry. Makes for a good cab for whatever speakers you want to put in. It weighs about 40 lbs unloaded.
