are you sure the BB has clean signal blended in?I use 3 different drives in my live presets. It wasn't hard to get something really useful.
I did notice that the TS and BB Pre had a mix of 100%, while the real life ones have some clean signal in the mix. Easy to edit that.
Also, the TS defaults to SI diode, instead of 4558/SI.
The defaults sound good, too, just not like the real thing (?)
