I received my Sadowsky SA 410 yesterday, and thought I'd post my initial impressions. I had previously been using a Bergantino NV610, and I absolutely LOVED that cab, but my band situation changed, and it wasn't necessary for me to carry 6 10s anymore, now that I'm not competing with two Marshall half stack weilding gui****s. After talking to friend, neighbor, and amp guru, Tom Bowlus, a bunch of times, and Jim Bergantino a few times, I came to the conlusion that the SA410 sounded just like what I was looking for. I wanted something with the massive punch and mid presence the NV610 had, but in a smaller package. I also wanted a bit more versatility, so thought a cab with a tweeter was the way to go. Initially, I was surprised at the small size of the box Mr UPS dropped off. It was indeed a pleasant surprise. This is probably the smallest 410 I've seen. Although it is no lightweight, I didn't have any difficulty getting it unpacked and in my house. I popped the casters on, and they fit securely, and roll freely. I plugged my Iamp 800 in the cab, and gave it a brief workout with my Lakland Darryl Jones with flats, and my new Musicman Stingray double bucker. In short, this cab seems like EVERYTHING I was looking for. It has an amazing punch and clarity, all the while retaining the patented Bergantino fullness. With the flatwound strung bass, and the tweeter rolled off, I almost would have been hardpressed to tell the sound apart from what I had heard out of my NV610. It punches you right in the gut, and I'm guessing it will cut through a band mix just as well as the NV610. Plugging in the stingray, and putting the tweeter on "flat", it had plenty of top end sizzle, all while retaining the gut punching mids and lows. The top end isn't harsh at all, and contains that magic Bergantino crossover mojo. I'm really eager to take the cab to the Bowlus Bass Borg so I can hear Tom's Sadowsky SA head through this cab. From what I understand, the head and cab were absolutely made for each other. I'm also really eager to hear Tom's SA210. This new Sadowsky SA410 cab, in a phrase, is probably the most versatile cab I've heard. It goes from pillowy old school, to cutting bright, modern tone, and excels at both. I think Jim Bergantino and Roger Sadowsky have a real winner on their hands here. Of course, this is all preliminary, because the rig won't be gig tested until next weekend, but from what I've seen and heard so far, color me impressed.
