I am experiencing random popping sounds when using the four-cable method through my rig. This 'digital matter' becomes more audible the longer I have my amp on and does not dissipate when the master volumes on both my amp and POD are turned down. Though the background is less present when I play with a clean preset, it's always there.
Here's my rig:
Schecter Hellraiser
Peavey XXX head
ValveKing 412 cab
Shure PG-14 wireless guitar system
HD500x Rhythm Preset reading from left to right: Noise gate (20%~) -> Screamer -> ENGL Fireball (no cab) -> TubeScreamer -> Spring Reverb (clicked off) -> DigiDelay (clicked off) -> Smart Harmony (clicked off)
I have tried the following:
- changed out cables
- playing without wireless
- plugged amp and POD through a power conditioner
- using only two cables running into my guitar and into the input of the amp
- eliminating ALL effects except for the amp model and adding effects one by one
- turning the noise gate threshold up OR adding more gates with lower thresholds **this helped, however, the notes do not sustain and die off unnaturally**
- playing through a completely different rig and guitar (Telecaster)
- plugging my rig into an outlet in a different room in the house
Line6 said it may be a grounding issue (loose chassis) but I'm not covered to mail it into them so I'm hoping I can get some advice before I make the next move.
