An update to the collaboration between Mythos and RJ Ronquillo!

In early 2019, RJ and Zach began tossing ideas around for a unique drive / echo pedal and the SusMaryOsep! was born.

What does SusMaryOsep mean? Well it’s a common Filipino slang word that mothers yell at their children.

But what is the pedal you ask? That’s a little more complicated!

V2 ditches the sliders for knobs and gives players a Silicon Treble booster, an updated Herculean circuit and the same, awesome echo.

The switching has been refined for less popping and no expense was spared in creating exactly what RJ wanted. 

The Treble Boost is Mythos' take on the classic germanium design, reworked for a more consistent Silicon Transistor. 

This gives the boost a slightly more aggressive and tighter feel.

And, with its 3-way tone switch, you can get those bright sounds but also a mid forward and bass heavy sound.

Pair it with the Overdrive circuit for one of the widest array of drive tones in a Mythos Pedal to date!

In addition, there are two internal trimmers that will allow you to tweak the gain range and the boost's bias. 

The Overdrive is Mythos' popular Herculean V2, slightly tweaked for a more open voice.

This already dynamic drive now packs an incredibly amount of headroom and amp-like response!

The Echo portion is the same as before with it’s PT2399 chipset.

The controls are now easily adjustable on the face, with two small dots to indicate RJ’s preferred slap setting!

This is a musical and fun to play delay that has a vintage voice that wants to runaway on you but never does.
