turns out I blew the Celestion greenie, not the CTS. Cheap Chinese junk. One of my vintage, UK greenbacks coulda taken way more abuse and it woulda sounded better, okay, maybe I would blown it.... but not at 5 or less.
So the CTS went in with the Fane Classic 50 and they compliment eachother really well. The CTS has nice compression, slightly earlier breakup and a chinier top, the fane has THE mids from heaven. Wow, I get it. With the dying Celestion out of the way the bass tightened up in a great way. Its got plenty of low end, but its punchier and more dynamic with no boominess. Greenbacks aren't so hot unless they are 60s/70s ones. The vintage freaks are right. I was wrong! Shoulda sold this one with the other post-90s greenies I unloaded recently, woulda made an extra $50-100.
The flatter fane speaker suits the amp a lot more than the celestion. Its not as clean as all that, its definitely growls in the mids and a little in the lows. Some of the grunt n the Who's "Live at Leeds" was the speakers. I have the amp set to just start growlin' as I dig in, but the speakers are giving up growl and crunch as they are pushed.
with a little research on goggle I found the CTS can handle 40 watts and the Fane can handle a good 40 without issue (its rated at 50, but Fane had a tendency to overrate their guitar speakers, Pop 50s blow at 30 watts.... the joke is they call 'em Pop 50s because if you show 'em 50 watts they POP). So the 2x12 can now handle my Traynor at full tilt. Its a glorious Hiwatty sound with the Fane in the mix. I wonder if two fanes Classic 12/50s would be better than the Fane CTS combo.... the CTS has great treble paired with a smoother speaker though.... hmmmm.... tempted to drop 100 bucks on another 8 ohm Classic from 1983.
