Psychic Modulation released Undertow, a Beat Bending Dub Box designed primarily as a Multi-FX Unit for beats and drum loops, with consideration for other uses such as synth, bass and even vocals. Regardless of what kind of sound you put into Undertow, it will boost your low-end bass frequency, crossfade the signal into a Speaker for lo-fi telephone EQ, and warm up the resulting tone with a Saturation Driver. Then pass your treated signal into the Echo for some dubby, phased out delays. Finally, you can go wild with the Bend Modulator, which will rhythmically shape the overall effect using phase-locked waveforms with adjustable start position for creating things like pumping drums and basslines, gated delay feedback, phaser and flanger effects, echo melting, spatial effects and more.
