The Joyo JF21 Splinter Distortion features sought-after, classic distortion tones. The unique tones that this pedal can produce resemble tones between fuzz and distortion, depending on how the adjustment parameters are configured. With adjustable Distortion, Filter and Volume knobs, you have the ability to shape the sound to get the precise tone you're after.
The pedal also features two switches. One switch will change the distortion type between "Stock" and "Fat", with stock giving you a standard, metallic distortion, and fat giving you a beefier, thicker distortion. The other switch is labelled "MOSFET" or "Stock". This adjusts the preamp setting, choosing a stock preamp or a MOSFET preamp.
