Hello - I am a newbie. I have had a Variax 500 for a couple of years and recently purchased a used PODXT, not the live or pro. I successfully installed all the required Monkey software on my PC and the POD XT works great via USB to the computer. I am using the Variax via its TRS cable into the PODXT, What I was wondering is can the PODXT be used to customize the sounds on the Variax? Is there an RJ45 type cable that works between the Variax and PODXT. Thank you for your consideration. Bill
