Agree, I had changed to a tung sol and it wasn't the same. Put the shguang back in and way better tone around so it stays in.
The surprise was changing the rectifier tube. Okay the sag from the 1944 RCA a guitarist would just love. The EH offered taught punchiness. There is so much delicious chewy color in the Monique that to crown it with immediate attack was my win!
This is why our notions get in the way. "15s have more bass than 10s." "1944 NOS JAN RCA Blackplates have to be better than the 2016 Russian Electro Harmonix rectifier tube." Not necessarily. The Ruby has a little bit more sag than the EH if you're tube rolling. As always, YMMV.
