Eleven Rack combines hyper-realistic guitar amp and effects tones with a dual-DSP-powered interface and studio-standard Pro Tools LE® software to create the ultimate recording solution for guitar players.
Introducing True-Z Among guitar tonehounds, it’s a well-known fact that input impedance — the electronic resistance found in the input circuit of the amp or effect you’re plugged in to — has a huge impact on your guitar tone. We realized that re-creating this electronic relationship was critical in nailing the sound and feel of our emulations. Others have tried to fake this with signal processing but we weren’t satisfied with a one-size-fits-all-approach. Each guitar reacts uniquely with each amp or effect — so we had to come up with a true analog solution that allows your guitar to interact realistically with our amp and effect re-creations.
That’s why we developed True-Z — a unique analog input circuit that replicates the input impedance of classic stompbox pedals and guitar amps, resulting in amazingly realistic sounds. It’s almost as if the True-Z input on Eleven Rack morphs into the 1/4" input jack of whatever classic stompbox or amplifier you are using. When you plug into Eleven Rack, you get the same response — and same great tone — as when plugging in to a vintage stompbox or guitar amp. You can also manually control the impedance of the True-Z input and set it to a value that suits your playing best.
