That's an interesting device. But I believe that Matt is saying due to the design and sonic signature of a preamp, the component itself acts as the tone control for the system with nothing in it's path to introduce noise. Plus, tube rolling adds to this capability.
At least that's what I believe and I don't look for tone controls on a preamp. However, in the digital domain, you can EQ transparently.
