RhPf Electronics announces Mosphoros, a handcrafted overdrive pedal built around stacked gain stages, designed to let players shape how their tone breaks up rather than simply increasing distortion.
Unlike traditional drives built around a single clipping character, Mosphoros distributes gain across interacting stages. The result is a gradual, controlled transition from clean enhancement to dense saturation, with strong touch sensitivity, preserved note definition, and a natural, organic response throughout its range.
- Drive: Sets the core texture, from transparent lift to natural, organic, amp-like breakup.
- Unique Bass and Treble gain controls: Increase gain in the low and high ranges respectively, shaping both tone and texture behavior rather than acting as traditional EQ.
- Wide output range: Functions as a clean boost, foundational drive, or primary saturation.
Drive, Bass, and Treble are not EQ controls. Each adjusts gain at different points within the circuit, meaning changes affect both tone and texture. Players can dial in softer, more organic textures or firmer, more focused drive depending on how the three controls interact.
With all gain controls at minimum, Mosphoros passes the original signal cleanly. At noon, it delivers balanced, expressive overdrive suited for blues, rock, and dynamic picking. With all gain controls pushed, it moves into thick, harmonically rich territory while remaining articulate and responsive.
Mosphoros stacks predictably with other drives, maintaining clarity and low noise across its full range. It is suited for players who rely on touch, guitar volume control, and stacking behavior to shape their sound rather than switching between disconnected gain presets.
Street price is $199 USD. Available now at select retailers and directly from rhpfelectronics.com.
