From Wampler’s Website: When we first met Tom in early 2012, he was already using our Euphoria and Paisley Drive stacked together to give him the tones he required. But something wasn’t quite right; those pedals are voiced for other genres of music altogether so we set about honing the tones to match his style of playing. He needed more transparency, a tighter and controlled response on the bass end and when stacked up they needed to sound and feel like an amp running at high levels and give each string complete clarity and response. Over a year later, we have the Dual Fusion. With two independent circuits that are based, but are completely modified, on the Euphoria and Paisley Drive.
