The Lil Mo is the compact version of RimRock’s highly regarded Mythical Overdrive, a boutique Klon Centaur-style overdrive/boost. It delivers the classic Klon recipe—clean boost, low-gain overdrive, and a subtle midrange push—but in a smaller, pedalboard-friendly enclosure.  

What it sounds like

• Very transparent at lower gain settings.
• Adds clarity, punch, and harmonic richness without drastically changing your guitar’s character.
• Tightens the low end and helps solos cut through a mix.
• Works exceptionally well as an “always-on” pedal or as a boost into an already-driven amp.  

Key features

• Authentic Klon-style circuit running internally at higher voltage for increased headroom.
• Top-mounted jacks for saving pedalboard space.
• Multiple clipping diode options that let you choose between warmer, earlier breakup or cleaner, higher-headroom tones.
• Handmade in Oregon with high-quality components.
