I have the Stomp hooked up to my computer via the USB. The guitar sounds as it should but when I play songs on my iTunes they sound like they are almost "re-mixed" compared to when I just plug the same pair of headphones directly into my computer jack and listen to them. Through the Stomp it's very dull sounding and not very detailed.
Is the playback that is coming through the USB running through some compressor or something?
Thanks!!
