JTV89F Mag grounding issue

[jpelzel 2]

Hi!

 

Wondering if anyone knows if a new input jack would fix this. Or if i should chase something else.

 

Here is what happens: JTV89F -> VDI -> HELIX. Mags give extra hum until I touch the end shroud of the VDI cable. Either end will do it. JTV end or HELIX end.  It hums like a single coil.

 

Using my 69S through the same path and I do not have the same issue. No change whatsoever when touching an end of the cable so I am thinking that at least rules out other components in the chain.

 

Thoughts?

It will have to be checked out by a Line 6 authorized tech who knows the product.

Ground hum could be anywhere in the circuit.
