Вот стырил камент буржуйского форума HD vs 11R
They are both cool units IMO (11R & HD).
They go about their sounds differently IMHO and depending on what you like, you may or may not like one or the other.
11R: brighter, more 3D sounding
HD: darker, more upfront sounding
11R is so simple to use. It's fantastic. The HD300 was pretty good but the HD500 is much more fiddly and you've got to sit down and play with it for a bit to get a handle on it.
I like them both but I've got a highly boosted plexi patch (TS>EQ boost>Plexi>Greenbacks>off axis mic) which (to me) just sounds absolutely fantastic for 80s high gain and I just cannot get the HD to sound like it. I can get kinda close but it's not as smooth or warm or as natural.
I really like the Fender models on the HD though. The deluxe is great. Recto is cool too.
The Vox AC30 on the 11R absolutely nails the HD IMHO. It's a great sim.
I mostly use:
11R: Lux, AC30, JCM800, Plexi, Mesa MarkII
HD: Twin, Lux, Plexi, Park, Recto
