I think I was the first to ditch the GNX4 in favor of the GT-8.Its effects selection and overall sound just strikes me as better.Line6 is a real contender.Line6 nails amp models,but ive yet to be overwhelmed with there effects selection,variation and sound.

I have my GT-8 running through my firebox or out of two roland DM-20 monitors.Sounds are clear and clean.Its the only floor board I would trust to take a beating too.
