Mythos Olympus Overdrive Pedal

From the listing

Seller's description

The Olympus Overdrive is a tribute to the incredible Gainster/Hoochie Mama circuit that has become much sought after on the used market. Known by many as a “Klon-Killer” and for good reason, it’s a powerful yet musical overdrive that only enhances what you already have. The Olympus features three interactive controls, Volume, Presence and Gain. The Presence and Gain controls work together to achieve anything from smooth lead tones to bright and chimey rhythm sounds. The overall tone has a very “tweed” like mid push but it’s not overwhelming and doesn’t mask the tone you guitar and amp have while the pedal is off. Sonically, the only change in the new version is increased low end and slight increase to overall gain to increase  flexibility.
