Well, Saturday I visited The Chicago Bass Club in Alsip, IL with my trusty Mod VJ4 and the sole intention of finding out what the hype was all about. I must say that Jorg's cabinets are indeed worthy of the praise. I tried a 1210, a 1212, 101012, and a 410. I felt that 410 would probably work best for me and I also thought that it sounded the best to my ears inside the store.
So I got home on Saturday and was able to talk my wife into jamming with me for a while (she's a drummer) and the 410 paired with my Aguilar AG-500 sounded fantastic. I'm not sure if it is Jorg's design or what but I think that this is the fullest sounding 410 I have ever heard. It still has the punchiness you would expect of a 410 but there is also something special happening that is hard to put your finger on. A warm sort of dispersion that just makes these cabs unique. I can't really explain it. It may be the emphasis of the low mids or just the design of the cabinet but whatever it is, it's great! The 410 really fills the room. Tomorrow night I'll get to try it with a full band and I will try to report back here with my review.
Also, I want to add that I really enjoyed my visit to The Chicago Bass Club. It is a great little store that sells Aguilar, Schroeder, Eden, Accugroove, Lakland, Modulus and other mid to high end gear. Mark, the owner is a friendly and helpful guy who is also a player. It is located in Alsip, IL on Cicero, just south of the Guitar Center.
