pangwin61 Posted December 18, 2015 Share Posted December 18, 2015 One main reason I would upgrade to the Helix from my HD500X is how it responds to rolling off the volume with the guitar volume knob when connected through the VDI. The response is terrible and unusable with the HD500X. Can anyone tell me if this function has been addressed on the Helix to respond as if it were plugged into the standard analog quarter inch?

shredjsx Posted December 19, 2015 Share Posted December 19, 2015 Mine works fine on my HD500x, Variax and my L3t setup... For patches on the Variax I set the volume pots to 500k and it has no problem 1 Quote Link to comment Share on other sites More sharing options...
pangwin61 Posted December 20, 2015 Author Share Posted December 20, 2015 After I made this post I remembered all the control I have by setting the knobs to control the amp gains, effects, etc and then locking them to prevent local control. I'm curious though, how do you set the pots to 500k? Quote Link to comment Share on other sites More sharing options...
silverhead Posted December 20, 2015 Share Posted December 20, 2015 You use Workbench with the JTV to set the pots. Quote Link to comment Share on other sites More sharing options...
PeterHamm Posted December 20, 2015 Share Posted December 20, 2015 I found the HD 500 to be much better suited to rolling off volume on any guitar, Variax (which I had for a while) and otherwise.I don't have a Variax currently, but I find the Helix to be way way better at changing the sound naturally when rolling off.

Leftzilla Posted December 21, 2015 Share Posted December 21, 2015 Definitely agree PeterHamm. The roll off on Helix with Variax is better than HD500 or 500X Quote Link to comment Share on other sites More sharing options...
vmoncebaiz Posted December 21, 2015 Share Posted December 21, 2015 You can use Workbench HD to not only change the resistance value of the pots (250k vs 500k), you can also change the taper of the pots from audio to linear. This might help you achieve what you want with volume roll-off. In general though, Helix is much more responsive to dynamics than HD500, and on either unit you'll find certain amp models are more responsive than others.

vmoncebaiz Posted December 22, 2015 Share Posted December 22, 2015 Audio to linear? Explain please Audio or logrhythmic pots are what I believe most guitarist prefer, or at they are what most are used to for volume control on a guitar. They roll off more evenly through out the sweep of the pot. Linear taper pots tend to have a big jump in the last part of the rotation 10-7 on guitar volume, but then have a smooth roll off from 6-0. I think most guys use linear pots for tone controls and audio pots for volume. But it's all preference for your control. Neither one has difference in overall tone, just the sweep. Cool thing about workbench is theres no soldering involved and you can quickly find out which taper you like better. Quote Link to comment Share on other sites More sharing options...
