Yup. It's true. Just got a pine, open back 1x12 cab loaded with a Weber alnico blue dog 50watt speaker. Took it to practice last night and played it at volume. It put a smile on my face. Not as "crisp" as a ceramic. A bit more "fuzzy" on the edges, if you will, but in a good way. Adds to the overtones of overdrive in a musical way. Otherwise, very clear sounding and not ice pickey. Beauty is in the eye (or ear) of the beholder, but from my standpoint, highly recommended!
