Hey. I'm just wondering if anyone here is familiar with the gnx 3000? if so I was wondering if there is a way to completely turn the amp modeling or preamp off so that I'm just using the effects on top of my amps own clean ad dirty channels. I have it set to direct. when i run it in font of my and it sound alright but it sounds a little digitally. when i run it through the effects loop the clean channel sound good but the dirty channel is right muggy and low gain. does anybody know how to solve my problem?
