My Spider IV-150 has developed an issue where about 10 seconds into a switched preset, the volume of the preset drops about 25%. This happens with all presets. Initially when this issue began, overdrive presets 10 seconds after selection, would switch to a line-level, clean tone... almost as if no preset were selected at all. After taking it to a tech that used to work for Line 6, he couldn't make it happen in shop (no surprise there). But he suggested doing a firmware update through Line 6 Monkey. I did that and now the presets don't switch to that weird, clean tone. The presets keep the sound but drop in volume about 25% after 10 seconds.
I just tried doing another firmware update but Monkey says the amp and MK-III pedal are up to date.
Is anyone experiencing this issue? And if so, how did you remedy the problem?
Can anyone recommend a good tech that really can trouble shoot and work on Line 6 gear in the LA, Orange County, San Diego County areas?
