I had the MarkUs and didn't care fir it at all and I got slammed here on the forum for saying so. I'm very familiar with Mark series amps as I have owned a Mark IV and Triaxis and my other guitar player in my band has had one for 20 years. His Mark IV is a particularly great sounding one from early 90's. Some of my favorite guitar tones (Dream Theater, Sevendust, Metallica) have been recorded with a Mark IV (or similar Mark IIC+).
The MarkUs didn't sound anything like the Mark IV IMHO. I compared side by side as his amp (along with my Engl SE670) is my benchmark for all the MTS stuff I've got. I know it was modeled after a IIC+, but still, it didn't even sound good as it's own unique tone...
Very flubby on muted chords, couldn't get the gain stages to sound good.
The "Scooped eq" setting is so exaggerated it's unusable. (Kinda like the guys on a Crate at Guitar Center trying to play Slayer)
I'm also not slamming Salvation. The Angel is my favorite right now an I will be receiving my Angel E in about 2 weeks. BTW, I had Anthony make all the voicing switches more subtle. I believe he makes the voicing switches too exaggerated (at least on the Angel and the MarkUs). I thought it would be better with an an in between setting (maybe I should have asked for a 3 way switch?)
Maybe there was something wrong with my MarkUs because the clips sound killer, but I'm sticking to my story. (I did change tubes also)
....Bring on the complaints!
