Anyone have experience with these? I was thinking one might make a great addition to my Origin20c and help achieve that vintage pulsonic speaker tone heard with the big boys of the era. They are a little more realistically priced when available compared the 12" pulsonic GBs, curious if they would get me in that area being a 10". Do they share any similarities in tone to the GBs? I know it's a smaller and different speaker but I imagine they still have a lot more character than modern 10" speakers. I'll add a revision here as I'm not very educated on vintage Celestion 10" offerings and am open to any input on vintage Celestion 10" guitar speakers.
