Mythos SusMaryOsep! V2

The Mythos SusMaryOsep! V2 is a three-in-one pedal that puts a treble boost, an overdrive and an echo in a single enclosure, with three separate footswitches so you can engage each effect independently¹. It is the updated version of guitarist R.J. Ronquillo's signature pedal with Mythos Pedals, originally debuted in 2019 and given what Guitar World called "a comprehensive internal and external face-lift for 2022"¹. It launched at $329¹.

The name comes from Filipino slang: a common word that, as Delicious Audio put it, "mothers yell at their children", short for "Jesus, Mary, and Joseph!"². The pedal is available now¹.

Treble boost, overdrive and echo in one pedal

Each of the three circuits has its own footswitch, so the Echo, Treble Boost and Overdrive sections can be used alone or stacked¹⁴. That stacking is the point of the design: the original idea, which R.J. Ronquillo brought to Mythos, was to put his favorite Mythos overdrive together with a slap echo in one box⁴.

Treble Boost. The boost section is Mythos' take on the classic germanium treble booster design, reworked with a silicon transistor for consistency. Guitar World describes it as "a silicon transistor-loaded reinvention of the classic germanium design", and the change is said to give "a more aggressive and tighter feel"¹. A 3-way voicing switch lets you aim the boost at bass, mid or treble frequencies, and two internal trimmers adjust the gain range and bias of the boost². On the original pedal, the boost delivered a tight, punchy clean boost with a slight boost at minimum and approximately 20dB at max⁴.

Overdrive. The drive section uses the circuit of Mythos' improved Herculean V2 overdrive pedal¹. Mythos says it relies "completely on the op amp for clipping", which they credit for "an incredible amount of headroom and amp like response"³.

Echo. The echo is a vintage-voiced, PT2399-based slapback echo with approximately 450ms of delay time². Mythos describes it as "a musical and fun to play delay that has a vintage voice that wants to run away on you but never does"³.

The controls

The V2's biggest control change is on its face: where the V1 used master sliders for the Echo and Boost sides of the pedal, the V2 swaps these out for master knobs¹. The echo's Time and Feedback controls also moved. On the original pedal these were side-accessible internal trimpots⁴; on the V2 they are front-mounted knobs, with a Mix knob and "two small dots to indicate R.J.'s preferred slap setting"²³.

The pedal is built with top mount jacks, true bypass switching refined for less popping, and what Mythos calls "top quality jacks, switches, pots, and components throughout"²³.

History: R.J. Ronquillo's signature pedal and the V2 changes

The SusMaryOsep! grew out of a collaboration between Nashville's Mythos Pedals and R.J. Ronquillo, a guitarist known for his pedal demo videos. In early 2019, R.J. and Zach of Mythos "began tossing ideas around to create a unique drive/echo pedal", which evolved into the SusMaryOsep²³. Ronquillo first approached the builder with the idea of having his favorite Mythos overdrive, the Herculean V2, paired with a slap echo in one box⁴. The original debuted in 2019¹.

The V2 arrived in 2022 with changes inside and out¹²:

• Master knobs replace the V1's master sliders for the Echo and Boost sides¹
• The overdrive section uses the circuit of Mythos' improved Herculean V2¹
• The treble boost is reworked with a silicon transistor in place of the classic germanium design¹²
• The echo's Time and Feedback controls move from internal trimpots to front-mounted knobs²³

The SusMaryOsep! V2 is an updated version of R.J. Ronquillo's signature effects pedal, a treble boost/drive/echo 3-in-1¹. The collaboration behind it began in early 2019, when R.J. and Zach started tossing ideas around to create a unique drive/echo pedal, which evolved into the SusMaryOsep²³. Ronquillo first approached the builder about the idea of having his favorite Mythos overdrive in a single unit⁴. Players interested in related Mythos circuits can look at the Mythos Cestus Treble Booster and the original Mythos Cestus⁵.
