Here's what Mythos say about the Olympus Overdrive
The first in the “Spartan” series of pedals from Mythos. This series is an homage to my earliest builds with a labor intensive design that uses the best possible components. The Olympus Overdrive is the first of this series and is a tribute to the incredible Gainster/Hoochie Mama circuit that has become much sought after on the used market. For the uninitiated this original circuit is known by many as a “Klon-Killer” and for good reason, it’s an powerful yet musical overdrive that only enhances what you already have.
The Olympus features Volume, Presence, and Gain controls. These three knobs are incredibly interactive, the tonality changes with the gain low and high so you have to use the Presence to voice the high end to fit your rig depending on how much gain you like. The overall voicing is ever so slightly mid-pushed and is often compared to classic “Tweed” amps of yesteryear. The Gain control allows you to go from a very natural boost to a gnarly drive sound that doesn’t step on the toes of your rig, just nudges it to an angrier sound.
The “Spartan” Series features the highest quality components I could find. Low Tolerance Carbon Comp Resistors, Large Wima Capacitors, as well as Silver Mica and Polystyrene caps offer up the smoothest and most natural high end. The Op-Amp in this circuit is a Texas Instruments TL072CP which has incredibly low noise and in overdrive circuits it offers up an responsive feel with nice clarity.
In addition to all the high quality through-hole style components the “Spartan” series features SMT designs that do all of the power filtering and protection as well as other utility features. None of the SMT components are in the audio path of the pedal.
