Bold Overdrive

Mosferatwo is built around the idea that overdrive should feel like part of the amplifier, not a layer placed on top of it. Its sound moves naturally from clean lift to edge-of-breakup grit and into thick, saturated drive, always staying responsive to touch and playing dynamics. Rather than locking into a single sweet spot, it offers a wide, continuous range of gain textures that can shift from bold and swampy to tight and articulate within the same circuit.

At the core of the pedal is a stack of carefully voiced gain stages built entirely around MOSFET technology. Each stage contributes its own character, combining soft and more aggressive clipping behaviors to create saturation that develops gradually and remains harmonically rich. Chords retain weight and separation, while single notes sustain with a textured, almost speaker-pushed quality that feels closer to an overdriven amp than to a conventional distortion pedal.

The Drive control shapes two gain stages at once, allowing smooth transitions from subtle breakup into heavier saturation without sudden jumps in feel or volume. Alongside it, the Focus control does not simply adjust brightness but changes how the gain structure reacts, shifting the response from loose and full to tighter and more articulate. This interaction makes the pedal behave differently under the hands, not just under the ears, and turns small adjustments into meaningful changes in attack, compression, and note definition.

Further shaping comes from the Heart and Bite controls, which act as focused boosts rather than broad tone adjustments. Heart reinforces low or low-mid content depending on its switch setting, adding either weight or punch without blurring the rest of the spectrum. Bite targets upper mids or presence, helping notes cut through dense mixes or stand forward in lead lines. Because these bands are narrow and carefully placed, they enhance clarity and impact without pushing the overall tone into harshness.

At lower gain settings, Mosferatwo works as a powerful clean or edge-of-breakup boost, adding body and harmonic detail while preserving the core voice of the instrument. As gain is increased, it moves into gritty, garage-style overdrive and continues into thick, fuzzy saturation that still keeps articulation intact. This range was originally developed so a single guitar could carry both rhythm and lead roles in stripped-down setups, delivering the sense of multiple layered parts from one signal.

Throughout its range, the pedal remains highly touch-sensitive. Light picking stays open and dynamic, while harder attack pushes the circuit into richer compression and harmonic density. The response encourages expressive playing rather than flattening it, making the gain feel connected to phrasing and dynamics instead of fixed at a single intensity.

Designed and manufactured in Switzerland by RhPf Electronics, Mosferatwo is a fully original overdrive built around interaction between gain stages, frequency shaping, and playing feel. It is made for players who want their drive to move with their hands, adapt to different roles in a mix, and deliver character without sacrificing control.
