Another commission, this time from a bassist wanting something filthy, funky, and classic
(And, I used an actual bass for this demo. Though, I did screw up and recorded with my Twin sim instead of the SVT I setup specifically for this demo
)
The Ocelot board is the most tweaked, as the goal was to get it closer to the Ampeg Sub Blaster, with the octave tone control from the Aguilar Octamizer -
The Brown Dog (MadBean Gas Tank) is stock
The two leftover outputs of the Spluffer are wired as dry outs
While the Ampeg Sub Blaster (schematic found on FSB) shares most of its circuit topology with the OC-2, it doesn't sound nearly as synthetic. Almost natural, actually - quite a bit clearer, and doesn't seem as prone to octave jumping
