Been researching OB for 604- perhaps not such a hot idea (although I'm still interested). Considering 620, 612, 606, or MLTL- would have smaller footprint anyway. Trouble finding specs for MLTL- did find "drummerwill's" older post with these specs: 44"X24"X19". I'm assuming Baltic Birch 3/4"/19mm- which I have found good source for. But there is no indication of size and placement of port or other details.

Would appreciate any more info if possible on MLTL or any new thoughts on 604 box.

Thanks, Kip.......
