I have an issue with excessive hum and the jtv59. I'm running guitar via VDI cable into a HD500. I'm using the magnetic pickups and the modelling at the same time and using a panner to switch between them. For example: Acoustic jmodels and panning into a heavy magnetic-based tone. I'm running XLR right out to a EV monitor on stage and XLR left out to board. I'm getting a horrible hum now. It has happened before but seems to have gotten worse. I switched inputs in the presets in the pod to just the variax (right before the gig in a panic) and the buzz is gone. Trying to brainstorm causes and solutions. The hum sounds like a typical ground loop. I've tried the ground lift on the pod and it seems to have no effect. This venue has bad power (as does a lot of places we play). Getting a few furman SS-6B filtering power strips that may help. I could just run to the board and the send guitar back to wedge. Thought about getting the pyle PHE400. http://www.mcmelectronics.com/product/555-16055?scode=DD1443&trk_msg=5JJO54U26DJ4B18OSAJ6TRMJ1K&trk_contact=765CTN3VQE3OND4R5FLA07VMJO&utm_source=Listrak&utm_medium=Email&utm_term=555-16055&utm_campaign=DD1443 Thought that is maybe a grounding issue in the JTV. If this was a normal guitar, I would gut it and foil and ground the pickup cavity. I'm a little hesitant to dig into it but will likely crack it open soon and take a look. I saw the pickup diagram that is flowing around. Afterthought: I don't know if switching to the magnetics would bring hum back. That would be a great test. Any help would be most appreciated.

I am running a JTV-59 through a Yamaha THR 10C into an iMac via USB or just jamming with headphones plugged into the THR. The magnetic pickups sound great with the amp sims built into the THR. In fact, I'd say the tube amp sims in the THR are some of the best hardware or software (external device or computer plugins) I have come across so far. Granted, I don't have an Ax FX or Kemper Profiler. But when I switch over to the Variax models with the same amp sims (both THR and Guitar Rig), it just doesn't sound that great. The mags sound much better. Then I finally got around to turning the THR to the "FLAT" setting where no amp sim is applied to the signal. I only had a light hall reverb on. When I started going through the models I was blown away! Especially by the SEMI, JAZZBOX, and ROCKABILLY models. To me they sound so much better without an amp sim coloring their sound, even when the amp sim is set to low-gain, clean tones. The sound is more expressive and sounds less "gimmicky". I am starting to have more respect for what Line 6 has accomplished here. I am not disappointed at all because I really like to play with very clean tones, and no distortion. I know this probably has a lot to do with the preference of my ears. I'm just very puzzled why there would be such a difference between mags and Variax models when using amp sims. Do we get better results using simulated instrument and real amp, or amp sim and real mags, but things start to break down with simulated guitar AND simulated amp?

I ordered some of the magnetic labels from Gigwrx last week and they came in yesterday. These are nice quality and I really like how they look. Just thought I'd share. I ordered more than I'll use at once, and one that I rarely would use to turn an effect off with a footswitch (reverb), but it's nice to have the label in case I ever want to.
