Im actually tracking with the THICK off. It was a little too much with the 121. The 121 is giving me a great body and the 57 is giving that cut. If i was only tracking with the 57 the THICK button might have been used. I wish the germ let you control how much THICKness you could give. But its a great pre anyways!!
I did try the 421 and that sound good to. At one point i was going to do a combo of all three but it just had too much mid. So pulling the 421 out did the trick for me.
I will post an example when i have a sec of the rough track
