When the V3 came out, I told the store owner that I was not interested and really satisfied with the V2. A couple of weeks later, I broke down and tried the V3 thorough an Orange. Immediate impressions were that this is a redesigned and more useful pedal and it seemed to sound better. Didn't have the V2 with me at the time to compare with. Only needed a few minutes to say "I'll take her home." Once home I put them side by side the V3's improvements really stood out. The V3 is really worth getting.
Hope things work out for you.
