SolidGoldFX Funk Lite Envelope Filter The Funk-lite is a pedalboard friendly envelope filter derived from our highly successful Funkzilla design, featuring a 100% analog signal path, a simple and intuitive interface, and the organic filter tones you would expect from one of our pedals. The Funk-lites controls for Frequency and Depth make it easy to quickly shape the character and timber of the filter while the Attack knob lets you dial in the envelopes response to your picking dynamic and instrument. The Funk-lite produces a smooth yet expressive tone without any harsh frequencies or unusable peaks that is perfectly suited for guitar, bass and keyboard applications. 9V DC Input: This pedal uses a negative ground, 9-18V DC power supply. Battery operation is also possible. Dimensions: 4.39" x 2.34" x 1.06" (112 x 60 x 27mm)
