I used to have a Boss GT-6, the effects were all very tweakable, lots of options. I took a bit of tweaking for me to get good sounds though, especially with fx.
I sold it and got a PodXT and then an Atomic Reactor amp (a 18w 1x12 valve amp for pod and other modeler boxes)
The Pod sounds much better through the Atomic, the valves give it a bit more warmth but it's still not a cranked Marshall, although the cab has a bass port, which is pretty cool :twisted:
The Pod doesn't have as much FX though, the emphasis is more on tha amp models, some are better than others, but I like the huge choice, it keeps me busy.
HJM: I'm sure you are right about TO having a VG88, I would love one of those with a MIDI pickup, you can do loads of cool things with them.
