Few pedals have such extensive effect parameters as the Soundblox Pro Envelope Filter. The sweep range controls the direction and width of your bass’ modulation. The speed controls how quickly the envelope filter opens and closes, as well as selecting the axis used for the Hot Hand device. The frequency controls where your envelopes main point is before sweeping. The mix controls your level of wet to dry signal.

The Envelope Filter’s powerful EQ settings are ideal for making fine adjustments to both your dry and modulated signal. You can navigate between types of LFO and envelope patterns, as well as adjusting up to +/- 12dB of seven EQ bands.

Soundblox Series

The Soundblox series of guitar and bass effects provide users with intuitive effects and extensive editing parameters. Each pedal consists a main effect’s structure, but with enough modulation tools to create a sound that is truly individual. Each pedal’s robust structure and backlit controls make them suitable for the stage and studio alike. The Soundblox pedals are fully compatible with Source Audio’s Hot Hand, which actively modulates your guitar from a wireless ring and interface unit. The Pro series also benefits from a seven band graphic EQ to further develop your signal path and tone.
