Hi,
Thank you for your replies.
Yes, I have got a 1/4" cable plugged into the guitar and no, I hadn't tried it with the battery pack removed, but I will and report back.
I only have one RJ45 cable at the moment. It is new, but I'll get another one tomorrow just in case it's not right.
Should this just a standard Ethernet cable (Not a crossover cable)?
There does seem to be a poor connection on the guitar side RJ45 as its LED does go to red if I jiggle the cable around, but it is green normally.
Could there be any problems with the interface electronics within the guitar?
The guitar itself seems to work and sounds fine.
Thanks again for any suggestions you can think of.
Cheers,
Luke (Australia)
