Hello! I've seen this discussed before, but not recently. In the older threads, it seems to be during the era that the 610s weren't quite so hot. I recently purchased an Ampeg 610 and while I am enjoying it, an NV610 just became available for a not-so-crazy price. Is the difference enough that I should go for it? It's a craigslist find in a city an hour away, so I can't exactly try it out in a band setting, so what have your experiences been? I mostly play harder sort of post rock stuff. Which amp would be best for that? Thanks guys!
