The Gain switch offers three distinct choices, the middle is “stock” gain, the left position offers a firm, yet smooth boost in gain, whereas the right delivers an insane level of creamy distortion.
The Voice switch subtly alters the compression and clipping, tightening up the distortion to be more manageable with greater levels of gain, while
rolling back some of the fuzzy qualities, delivering a modern, high gain distortion.
Always using only the highest grade materials as standard, Wampler went one further this time but allowing you to swap the chip ... why? Simply put, the LM308 chip is regarded by many enthusiasts to give the best sound for this style of distortion BUT they're super rare. Instead of Wampler providing a limited run pedal they have provided an amazing sounding pedal with the option to add a different chip if you can find one.
The truth is it sounds just as good as the classic pedals we have on TonePedia, please go ahead and compare them yourselves.
