That looks like a great compressor. It even gives you control over ratio like in a studio. Also it has blend which is the most important control for me. I have three compressors, one for bass (always on) and two on my guitar pedalboard (one always on and one for endless sustaining leads). They need to be transparent. Although no one could ever tell I have it on my bass, I can sure feel it when I play.
The rare/elusive Rumble 112 is something I'd sure like to find locally. Not only is it a perfect fit for the 500, it is also a perfect match for the 200 like I have, which would give me the full 200 watts. If it came available here, I'd sure want to be the one who ended up with it.
I've never understood why they discontinued the 112. And I really will never get why Fender didn't make a 115 to match the size of the 200 and 500.
I wouldn't let a 112 get by me if ever found one, that's all I'm really saying.
