I am an Alnico fan, and yes, this is now my favorite speaker. I admit the Celestion 100 is a hard speaker to beat, but my ears say this is a sweeter and more pleasing. I can set the tone to any of the 3 basic sounds: clean, mild overdrive, heavy overdrive and play indefinitly on the single selected sound. With other speakers I lose interest after a while and must switch to another patch (of course the sounds must match the song). I have been building/assembling guitar speaker boxes for 55 years, have tried most speakers, and may continue to experiment. Yet I doubt this speaker can be reoplaced. By the way, the reference is low volume playing in small rooms with 6V6 power tubes, so the nuances are easier to hear I think.
