Got this amp a few weeks ago. I was searching for an amp, that allows me to dial in the historic pop, blues and rock sounds. At first I wanted to buy the head with a 4x12 cab, then my brain kicked in and I bought this one. For those unsure about the combo: The combo sounds absolutely mean with tons of bite and low end, if you want to dial your sound in like this. Careful with the weight tho, the box says already "2 man lift", so plan ahead how youre going to move it. As others have written before me I can confirm, that the clean sounds, that Marshalls delivered 25 years ago are a thing of the past, with the 410c you can even get Fenderish cleans.
Coming from a Boss Katana maybe the best description of tonal difference is: The Boss Katana sounds like watching a rock concert on TV, the Marshall sounds like that concert is happening at your bedroom. It's not just the bare tone, it's the animalistic growl, that the Marshall produces, it's the extra overtones when you start stacking individual notes. The amp sounds great on minimum loudness and can be played at night in an apartment (at least clean), but be warned, I don't find more than 10-15% of master volume doable in an apartment, the amp has the power for a real stage. I personally bought it for the tones and I accepted, that I won't be able to crank it at home as a downside. On the other hand even the Katana is too loud to truely crank at home. The Marshall gives me the feeling I ended the search for an amp and settled, to me it leaves nothing to be desired (except for a place without neighbors), a truely fantastic amp for many styles, that allows you dialing in the tones of many fantastic records and not just "get close".
