I can confirm that the tracking on the Future Impact is absolutely a non-issue, it's very, very good with both my 18V active and passive basses, and roundwound/flatwound strings. I also regularly gig with the original Deep Impact, and this new pedal is SPOT ON. It not only replicates some of the key sounds that I get out of my original, it offers many more possibilities with it's 99 patches and MIDI capabilities (which I have not yet explored, but it sounds promising).
