New, Unused Wampler Pedals Pantheon Deluxe DUAL OVERDRIVE Wampler I never ended up using it after I bought it! It's a new, unused item. The PANTHEON is now available in a dual-channel version! The "PANTHEON OVERDRIVE" has been updated as a dual-channel overdrive pedal! Equipped with a 3-stage GAIN level and a VOICING switch, it offers flexible operability and can produce traditional and wide-ranging drive sounds.
