The Bigfoot Trouble Booster XL is an incredibly flexible dual boost pedal with a plethora of modern and classic tones. The pedal has 2 settings: the Bright mode is inspired by the vintage Greg Fryer and Dallas Rangemaster treble boosters, capturing the classic Vox AC30 Top Boost and Brian May (Queen) sounds. The Normal mode provides a wealth of fatter overdriven tones inspired by Billy Gibbons (ZZ Top), packed full of rich harmonics.
