Hello Everyone,

I bought a Line 6 Spider IV 4 amp recently. I did some research on this amp  before buying it. I like the effects and features that are built into this amp however the problem I have is with the distortion. The distortion sounds kinda weird. From the video that I heard from youtube, the distortion sounds are decent to me but when I plugged in my guitar and play, the distortion sounds very unpleasant. It's like providing so much feedback and the distortion sounds are very sharp which result in ear piercing.

I am wondering if anyone can provide me some input here? Thank you.
