So I tested further by feeding pink noise into the effect return, and record the direct out signal from my DT50. This is to eliminate the impact of the changes in the HD modelling in the firmware upgrade. LVM is off, since in firmware 2.0 the effect loop got bypassed (according to documentation it shouldn't, but anyway). All settings are identical.
Looking at the spectrum of the two recordings explains why the direct out in firmware 2.0 sounds horribly thin and harsh - it sounds like it has no bass at all!! Looking at 100hz, it is more than 12 db lower than in firmware 1.2. As a result, the direct out in firmware 1.2 sounds warm and authentic and just like the real cab speaker, while in 2.0 it sounds horrible!
So Line 6, what is going on? Anyone can confirm the same behaviour in your DT?
Firmware 1.2 direct out, feeding pink noise into effect return
Firmware 2.0 direct out, feeding pink noise into effect return (what happened to the bass??):
