After, rather foolishly, selling my Variax 700 last year, (unintentionally to a Line 6 UK employee) when it developed a fault, instead of having it repaired, I recently bought a 500 on eBay.

It came in the case with the manual, power supply and the XPS box but no TRS cable. It works fine on batteries.

Although I never had to replace the cable in the 6 years I had my 700, I remember reading it was a standard 15ft TRS cable.

I thought I'll Google Variax TRS cable, which in the UK, yeilds very little. It would appear Planet Waves have discontinued making it.

So, I bought an unbranded but good quality TRS cable.

When I plugged it in and connected the power supply, only the red light came on (the 1/4" light was green). I remember the light should be green.

All my amps are at my rehearsal studio, so I don't know for certain there was no sound but I'm concerned I may have done some damage to the guitar.

Does anyone know why a standard TRS cable (5 metre to be exact) would not power it up properly or know where to get hold of the correct Planet Waves cable, in the UK?

Thanks.
