What Is The Soundblox 2 Manta Bass Filter?


The Soundblox 2 Manta Bass Filter is the next generation of the popular Soundblox Pro Bass Envelope Filter. The Manta features 12 finely crafted filter effects plus eight variations of distortion, a feature not seen before in the Soundblox line of filter effects. These Distortion Types are not just crunch, or amp simulation; they are specifically designed to work in tandem with the filter effect selections. The pedal’s filters are controllable by its 2 envelope followers, or sine, square, and saw tooth LFO. Plus, like all Soundblox 2 pedals, the Manta is compatible with the Source Audio Dual Expression Pedal, the Hot Hand 3 Wireless Effects Controller, or MIDI control signals via the Soundblox HUB.

The Manta features a very unique signal path, internally splitting the instrument’s dry and distorted signals. The dry signal alone controls the envelope, increasing the playing response from the filter. The pedal’s 12 filter effects include 2 and 4-pole Low-Pass, Single-Peak, Multi-Peak, and Phasers. The Distortion Types include Hard and Soft clip, Octave distortion, Fold-back, Quantized, and synth-like Gated Fuzz. Each distortion has independent gain levels adjusted by the Drive control.
