Euripide 14 Posted April 25, 2020 The fuzz face model seems a little hard to tame with my jtv-69 through the VDI cable. Is it possible that there are no impedance simulation mode to emulate a lower impedance with a fuzz face model when using variax through VDI? Since the impedance is unavailable when Selecting variax model as an input block, I was wondering how it’s actually working within the Helix when a fuzz face is the first in chain in that context. l’m pretty sure only someone from Line 6 will be able to give a definite answer to that question, but I post it here anyway. Thanks’ in advance Quote Share this post Link to post Share on other sites
silverhead 8,818 Posted April 25, 2020 The Input-Z parameter is only available through the 1/4” Guitar input on Helix. It is an analog circuit and does not affect the VDI input. Quote Share this post Link to post Share on other sites

I have seen this come up before. What would be the best way for VDI connections to deal with the impedance question? Have them digitally emulate the ideal impedance for the first block in the signal chain? Is impedance matching somehow not required with a digital input signal(Variax VDI)?

Since the TILT boosts lows while cutting highs (and vice versa in reverse) it's also provides a "pseudo shift" in the peak resonance which is what happens to a pickup under load. That shift can also be fine tuned with the frequency control if one feels ambitious. 21 hours ago, Euripide said: The fuzz face model seems a little hard to tame with my jtv-69 through the VDI cable. IMO, I would try the TILT EQ before the fuzz, and dial it back to about "dark 30" then adjust from there. Have a footswitch turn both the tilt and fuzz on/off at the same time as if they were working together. 2 Quote Share this post Link to post Share on other sites

Great suggestion. 1 Quote Share this post Link to post Share on other sites
