Hey Ken,
If you still need a light weight cab, give Marc at DR. BASS a call. Phone #; 843-278-5227. web site;
www.drbasscabs.com.
We can also build what we call "Air Heads"; a cabinet with a 2,3, or 4 space rack on top to add your favorite head, making it your own custom combo.
By the way, all 3 of my basses are doing just fine. Folks here in Myrtle Beach,SC just love the MD-7.
Looking forward to hear from you!
