Scale has little to do with it. My full-maple Carvin is 25" scale with an ebony board, and it has the basic EQ profile of a jcm800 lol. It is anything but muddy even with an Invader, which only on the internet is a muddy pickup.
On a shorter scale just bump up the gauges by a notch and there...
^^^ Exactly this.
You want something thick with fat lower-mids and not too much upper-mids, or at least not a dominant upper-midrange.

Between my four rectifiers I'm sure at least one will outlast me lol.
Only one of them has ever needed service yet, and that was my 95 dual needing some new caps, a couple new pots, a loose chassis ground fixed, and by choice a different effects-loop jack to convert it to their original factory...
Those are really great. If set to the "standard" clean-boost with level at max and drive at 0 they are cleaner than the basic ts9 or 808.
Sometimes I use the toggle in normal with the drive at 9:00-11:00, and other times with the toggle in boost with the drive at 8:00-9:00.
Even using the drive...
Yeah I'd agree to trade it or sell it and go for a Mesa.
Oversized/Recto slant is very close in regards to internal volume compared to a traditional-size straight cab, so don't resist the very easy to find recto-slant, even if it's much newer than the 2000's era it will still have the 8ohm UK...
81/85 at standard 9v
edit; As Rex mentioned, buy the old logo emgs if possible, and if buying the modern logo shoot for before 2015 and you will be getting good versions.
I bet they would mix very well with the CL-80. I'd put both reds on top if mixed in a 412.
CL-80 have the loudest perceived volume to my ears of any Celestion model.
So what about the series2 single/rectoverb? It allows for EL34s to run while using diode/bold. (?)
Personally the only pair I've used in mine are the mesa str-447 yellows.
Yeah I wished they were switchable too. Parallel is great if you are running something like a single chorus, but trying to get a wet/dry balance across multiple pedals can be impossible, and then obviously it's a problem with time-based stuff like delays.
