I will second the remarks that the Marshall sounds best loud, and that you can go some ways toward taming the fizz by putting a lower gain preamp tube in there somewhere. There are various threads on this topic on various forums with lots of different opinions. If you’ve got some lower gain (5751, 12au7, 12at7) tubes to try out, it’s a cheap and easy way to get things sounding different.
I went so far as to also change the power tubes out for a nicer, vintage pair (ANOS Siemens/Telefunken). The DSL40CR is easy to bias by the consumer because it has terminals for hooking up a multimeter, so trying out new power tubes is a cinch. Tube swaps went a long ways toward getting it less fizzy at lower volumes, but I also really improved things by ditching the stock speaker and throwing a Creamback in there. I went with an M65, which I picked up used figuring I could sell it for about the same if it didn’t make a difference. It certainly did. There’s not a hint of fizz at any volume now, and the higher gain channels are much more usable across the sweep. I believe I went with the 12AU7 in V2 but I experimented a lot and forget at the moment. Do your own research and experimenting before you give up on the Marshall.
Incidentally, I say all of this as a diehard blackface fender guy, but there’s just something about the crunch you can get from a Marshall circuit that a stomp box can’t give you.
Speaking of pedals—the other thing you should really try if you aren’t loving the tone is a tube screamer or some other time-honored classic boost pedal before the drive channels. I hate tube screamers into a clean amp. But there is something magical about using them to push a dirty Marshall.
