My oldest is my favorite - '47 Masco MA25P clip

[Riffraff]

I picked up a Mass 100 to use with my YBA-1 two weeks ago and got a little experimental with it last Sunday and tried it as a load box with a bunch of my lower wattage amps. It was no surprise that my standout favorite was my '47 Masco MA25P tube PA conversion. Here it is into a Weber Mass 100 set to load with the line out into a DL8 delay & Hall of Fame reverb then into a MosValve 1160 power amp pushing a pair of 212 cabs. No dirt pedals, just a Les Paul Standard straight in. The amp was turned up around 4-1/2.

That's one heck of a sound. I could play with that all day long. No dirt pedals.......magnificent.
