There's no more goodies in that abv. Darker roasts relate to higher temps, and a bunch of different variables. I'm sure I can get it darker but that'll be a bowl 4 try. Your not gonna get black avb, it's not designed for that. It's designed to deliver a consistent experience for everyone. Newbs, vets, and in between. The signature is one of its own for sure! Plus it pumps! I use a TM from the pre-order and the crafty cause they're kings and work well. I bought a TM2 and it's new in the box because TM 1 still kills it 4 years later or so? Maybe 3 years I forget but the 2 are the best portables in my collection along with the TA.
