This is the Solid Gold FX Funkbox envelope filter. The Funk Box was built with simplicity and versatility in mind, featuring a huge variety of tones and easy operation. 3 dedicated knobs control sweep, sensitivity, and resonance, and the fourth knob is a 6-way rotary switch that sets the sweep. There's also a sweep reverse switch with it's own LED on the Solid Gold FX Funkbox. This lets you swap the sweep on-the-fly, opening the door to even more creative possibilities. Tonally this filter maintains a smooth, warm character at all settings, having more in common with a vintage italian wah than your average off-the-shelf auto-wah. The Solid Gold FX Funkbox is handmade in Canada with some really, really nice components and true bypass switching.
