I just bought a Helix LT and, while I wasn't thinking of using the amp models, I'm starting to change my mind. I've been able to get rid of some of my pedals so this might be another improvement.
However, I've never played without an amp so I don't really know what would I use instead. I'd rather not use the same PA system I use for voice and keyboards in my band, but a separate "something" ^_^U
Any recommendation (at around 500€ maximum, if possible) would be greatly appreciated :)
PS: Helix ROCKS!
