It is a Mission Amps 5E3 tweed deluxe. I can't recommend Mission Amps enough. Everything is top notch quality, including the service. I am so proud of how this turned out I had to share. The cabinet is in the mail as we speak and will be here early next week. This chassis and an alnico Celestion Blue is waiting for it. Can't wait. I plugged the chassis into my Deluxe Reverb's Weber Blue Dog to hear it for the first time. I couldn't turn it off! It sounds awesome, if I do say so myself! (Sorry the pics are so big).
