An improved version of the brand's bestselling Charlie Fuzz, the Kink Guitar Pedals Psychedelic Charlie takes the one-knob fuzz and adds an external bias control.
Mark at Kink Guitar Pedals has also added a "pickup simulator" to the circuit, allowing you to place the fuzz anywhere in your signal chain, even after a buffered pedal (fuzzes are notoriously picky and tend to only work properly if they're the first pedal in the chain).
The Psychedelic Charlie is a silicon fuzz based on the classic Colorsound Fuzz Box, and it offers players fat riffing and killer fuzzy lead tones. Adjust the Bias control and you can achieve a range of sounds from on-the-edge spluttery notes and chords to a saturated, aggressive character.
It may have a diminutive footprint, but the Psychedelic Charlie sounds massive!
