Hello there, I was trying for the first time to record my guitar through the headphone jack of my spider iv 30. I've connected a cable cinch cable to the amp (headphone output) and to the line in input in my pc. Well the problem is that the quality is just terrible. The distortion (metal red) ist completely different and also sounds liks the sound were overdriven, like too loud. Changing the distortion type and channel/main volumes doesn't help at all. I've also tried 2 different adaptors (small to big cinch) and it also didn't help. I was wondering if this a know problem of spider iv 30 amps or that maybe my amp has a problem regarding the headphone output. Any ideas? Thanks in advance!
