I love this amp!
I've been playing it more and figuring out how the eq works. The mids are not surgical, most of the tone shaping happens between the treble/presence, and you can add a ton of bass without it getting wooly or flubby. It stays tight.
I read somewhere that the 50W has less mids than the 100W and this is fine by me. So while the mids may not be surgical, it really loves a boost pedal in front. Both the blue and red channels take an SD1 perfectly.
The big surprise though is that even though the amp has a single presence, I can get two completely different sounds on blue and red channels. On the blue channel, I can get mild rock to high gain liquid solo. And on red channel I can get thick, evil metal rhythm and engage boost for sharp and aggressive solos.
With the right boost pedal, it feels like a six channel amp.
I do think you have to choose the right speaker cabinet to get your perfect sound. The XXX cab works well enough, but is a little smooth on top. I'd love to find a used 1960 or evh cab. Searching for a used Marshall cab now. I haven't been able to crank it, and I know everything changes when you get some volume.
I was worried that because it doesn't have alot of options, it wouldn't be a versatile amp, but it is really versatile. (Still need to find a boost that gives edge of breakup on clean. ) In a perfect world, it would have something like a bright/raw switch to give it some more top end aggression so it would pair better with dark cabs.
