Here it is; my beloved Sub-Blaster. Sounds sweet and looks cool. I added an absurdly bright blue LED a few years ago. I'm finally getting around to rehousing it as it's crazy heavy and way too big for the pcb that's inside. First a comparison for size. You can see the discrepancy in footprint as well as weight. Ampeg box: 2 lbs 9 oz. 6.75" x 4.5" Hammond 1590MBK box: 7 oz. 4.75" x 3.94" The 1590M (the extra BK just stands for black finish) is a cool enclosure in that it's just a bit wider than the very common BB size boxes. This was necessary as the pcb is just a hair too wide for the BB boxes.
