This all sounds borderline between something actually faulty and something to do with general set up. Don't know much about the SC20 but there is a common theme running through all the comments suggesting that the Amp. does fill out when cranked. Treble and presence settings will also revolve around bass and midrange settings. When recording with my JCM800 Jubilee 25/50, I would run the presence at about 7 and the treble around 8. That would sound crappy until I dialed the bass up to around 9 and the midrange up to about 6 then it all takes off with a good nudge on the master volume.It not the nature of the amp, if it was I’m sure there would be a plethora of folks complaining, and there’s not.
I’ve had my SC20 for over three years now and I don’t have the issue you and the op are describing. I run my treble around 5 and the presence about the same, maybe a bit higher, and it sounds great! No issue at all.
With the amount of people who own these amps now, I suspect we would’ve heard many more complaints if this is the “nature” of the beast.
