I met a cool Craigslist seller today. The guy had enough repurposed gear to outfit a band on the moon. He had a Pro Jr Chassis that was screwed into a larger speaker cab and he wanted to part with it. I love ProJr’s and I’m going to make a P Jr head. I’d like to build a head cabinet that would let the knobs face forward (Like on a DRRI) but then the tubes will point straight back. I don’t know if that’s ok. It’s probably going to be a tall slender box. Any advice? The chassis.... He had the original Fender tubes in bubble wrap. I don’t know how to date the chassis it I’m guessing that it’s older. I’m looking forward to a table saw project in the garage. I can build a bird feeder so I think I can handle this. I built a Pathfinder 15R Head once and it looks like a bird feeder. Good times. Good times.
