Switch on variax with VDI cable

Recommended Posts

I have a JTV 59 variax. When I use it with my VDI cable into USB with its interface alone, the guitar emulation system is off. Knob leds are off.

If I put a 1/4 jack (with nothing on the other end) the JTV turns on and I can change guitar with the knob and seeing it change on Workbench.

 

I've seen videos of users with helix and variax jtv, using only its VDI cable.  It's enough to turn on the Guitar?

Or I must use a 1/4 jack to switch it on?

The VDI cable powers the guitar automatically; you don't need the 1/4" cable to turn it on. But you do need to push the model knob down to turn on the modelling and the lights.

Furthermore, you can use Workbench HD through Helix (LT)!

(Only if you use the little USB interface, you have to plug a 1/4 jack into JTV...)

Thank you. the cable itself is not enough, I need to attach the other end to a helix to power the jtv, right?

 

Is it possible something went wrong with my jtv vdi jack? I tried once with an helix that wasn’t mine, and it didn’t turn on.

 

I want to know if my jtv is capable of working with the vdi cable to decide to buy an helix lt, but it’s out of stock in my guitar shop. Is there any test I can do to find id there is any hardware problem?

Yes...the VDI cable cannot suck power out of the air. Leaving it dangling from the guitar won't do much... not to mention making it rather difficult to hear if it's not connected to anything. 😂

It’s not a stupid question as you quoted. With the battery and a 1/4†cable you can push the modeling knob and turn the guitar on.

I asked if with the vdi cable it’s not the same.

If you plug your Variax into a Helix (LT) (I had a Firehawk before and it worked too) with a VDI cable, the variax will be supplied, you won't need battery or other 1/4 cable.  ;)
