Chord Hugo TT2

I have not heard it on a set of cornwals, but after owning a TT and a Dave, I would recommend you skip the TT and M-scaler and get a used Dave. its about the same price and the Dave is far better then the TT and M-scaler combo. I fond the m-acaler to be ok upgrade but not for the cost. I could only listen to the m-scaler at the lower levels the higher levels were a down grade. 

I also haven't heard it with the Cornwalls but do feel that the TT2 is a little on the bright and aggressive side. It's an improvement over the original TT but still not there yet in my opinion. Some people really love that sort of energetic presentation, others find it fatiguing. I don't know how the M-Scaler impacts things though, sorry.
