I'm looking for a decent distortion on this spider iv 75 and I can't quite find one. I read another post where someone had the same issue. The distortion tends to have an ear piercing tone. I bought the spider iv 150 and traded it for the 75 because I heard it has a better sound. (kicking myself for that now.) but this one is the same. Now I'm not looking for studio sound out of this amp but something that doesn't pierce and has a little more clarity would be nice. amp is upgraded firmware(2.0) and i've messed around with near every possibility. If anyone has a decent heavy distortion and wish to share their settings, id appreciate it. I've tried it with about 5 guitars and its not the guitar tone. The old line6 ax2 sounds twice as good imo.
