Boss VF-1 Effect Processor

Is anyone familiar with both the VF-1 and GT-6?  I'm thinking about 
buying a VF-1, but since by far my main use of it will be with guitar 
I'm wondering if I would do better with a GT-6 instead since it would 
give me easier access to most controls.

I've played with the VF-1 and like it, but haven't found a GT-6 in 
stock yet.  Does anyone know how the two units compare?  Do they use 
the same basic models and effects?  Is the quality of effects roughly 
the same?  Are the algorithms similar?  Since the GT-6 is newer, does 
it have more or better amp/speaker models?

Also, since the VF-1 has been out for 2 1/2 years, I'm wondering if 
Roland will be coming out with a "VF-2" soon.  How far apart were the 
releases of the SE-50, SE-70, and VF-1?

Thanks.

For guitar, the GT6 has way better amp sims than the VF1.

The SE-70 was approx. 4 1/2 years old when the VF-1 hit the market.
I don't expect Boss to come out with a newer version soon. I have no 
personal experiences with the GT-6 but I've read a lot about this unit   
and the amp modeling thing seems to be improved in comparison with the 
older GT-3 and VF-1. The biggest advantage of the GT-series is that 
you don't need a MIDI foot controller to change patches or parameters. 
If you already have one, well.... On the other hand the VF-1 is more 
flexible in combining several modulation effects. You can't have Pitch 
shifer, Phaser, Tremolo, Ring Mod at the same time with the GT-6. With 
the VF-1 that is indeed possible (keyboard algorithm).
