The Pantheon from Indiana-based pedal company Wampler is an overdrive circuit voiced after Marshall's Bluesbreaker Stompbox, which itself was based off of the brand's legendary amplifier. A super transparent circuit that's a favorite of players like Eric Clapton and other British blues rock greats from the mid-'60s, this pedal aims to deliver the same kind of signature breakup the original amp is known for. It features bass and treble knobs, a presence knob, and three-way switches for both gain level (with a complementary knob) and overdrive voice, which lets users select their clipping type.
