The Density Hulk is a subharmonic synth pedal from Mantic Effects, known for its ability to generate powerful low-end equencies. It features premium quality components on a hand-etched, hand-soldered PCB and includes a mechanical True-Bypass via a heavy-duty 3PDT footswitch, ensuring a rugged construction. The Density Hulk was later updated and downsized into the Hulk, which retains many of its predecessor's features but in a smaller enclosure. The original Density Hulk was larger and more complex, with a focus on delivering deep, impactful bass tones.
