Yep, they have the vintage power section....you crank the power section on these and they WARM up and if you do that to a Framus it's the opposite, it get's tighter and meaner. The Dragon's like a JCM800 (with added gain) in reverse. the thing's dark and chewy at low vol but tightest amp i've used cranked up.I thought this too when I got my first MV (a JMP 2203). Then I realized the spikey treble is from running at too low a volume with the pre amp gain cranked. This goes away dramatically as you play the amp louder. If you want to tame the treble at low volume / high gain, cut way back on the presence (mine's at 3) and treble 3-5. Or if you can attenuate at all, just crank the master vol up some and problem fixed (I usually turn the presence back up around 6 or 7 here and Treble to about 5-6.
You can also try a Telefunken in V1 which I loved to fatten up and make a trebly sound growl more.
