It has an FX loop, right?
I love highgain halfstacks with a Nanoverb or other FX unit in the loop, for playing at reasonable levels. Any unit with a send, mix, and return knob on it will allow you to have the amp turned up, then use the FX unit's output knob to bring the volume down to a crawl. For live, you can either run the amp bone dry, or use it with the Fx unit's reverb set real low, just to add some air.
Try it on your Hotrod 50!
