Well, I have had the chance to play through a new-to-me Berg NV610 but have not had the chance to really turn it up. Really punchy sound with both the Brase and 535, but not with the harshness that I have had with a tweeter in the past (not with the Epifani, other cabs). So far, this is a keeper - great sound that grows on you. I was a bit worried about loading it into and out of my truck but that is not a problem. The handles and the configuration makes it pretty easy, even though it is not a light cab. Anyway, thanks to John at Bass Alone - as usual he gave me a good deal! Dan K.
