Description
Unleash your sonic creativity with the Schlappi Engineering 100 Grit, a dynamic Eurorack module that fuses the gritty charm of analog with the precision of modern modular synthesis. Designed for adventurous sound designers and musicians, the 100 Grit is not just a filter; it's an entire distortion playground housed in a sleek 14U width panel.
At the core of this module is a robust low-pass filter (24dB/oct.) that offers unmatched control over cutoff and resonance, allowing you to carve out rich, textured sonic landscapes. With two FM inputs—one featuring an attenuator—and two adjustable audio inputs with the option to overdrive, the 100 Grit serves as a versatile tool for crafting everything from smooth, creamy tones to aggressive, distorted waves.
The OTA-based VCA adds another layer of versatility, providing gain control and a CV input with an attenuator for nuanced sound shaping. A standout feature is the distortion output stage with a gain switch (x100), perfect for pushing your sound to the extreme. For those who love tactile interaction, eight brass contacts invite you to connect different parts of the circuit using your fingers, cables, or metal parts, encouraging an interactive approach to sound design.
All inputs are normalized to various circuit sections, allowing for creative feedback and self-modulation. With separate outputs for the VCA and distortion stages, this module is a powerhouse for any Eurorack setup, inviting endless experimentation.

User experience
-
Several users have found the 100 Grit challenging to integrate effectively, leading to its removal from their racks in favor of other distortion solutions.
Source -
Owners advise using sufficient envelopes to control the 100 Grit, as its feedback can act like an additional oscillator, introducing significant noise.
Source -
Owners find the 100 Grit difficult to control, but it offers a "high fidelity" sound, being particularly effective on mid-range sounds.
Source -
Some users found the 100 Grit more effective when patching it without inputs and treating the gain knob like a guitar pedal's distortion control.

Use cases and applications
-
Some users find the 100 Grit to have a sweet spot for bass sounds but less appealing for drums or leads, emphasizing its niche use in certain contexts.
Source -
The 100 Grit is highly effective for death industrial and martial industrial genres, delivering unparalleled distortion compared to traditional pedals.
Source -
The 100 Grit is noted to be more effective when used with certain oscillators, like the Piston Honda, offering a range from slight saturation to extreme distortion.
Source -
The 100 Grit excels at creating harsh noise and self-oscillating feedback, making it suitable for experimental and noise music genres.
Source -
The tanh3 by Instruo is recommended for those seeking a distortion module that can also function as a limiter and handle stereo effects with adjustable wave folding.

Comparisons
-
The Bionic Lester MK3 offers overdrive but lacks the raw aggression and distortion intensity of the 100 Grit, making the latter preferable for extreme dirtiness.
Source -
The 100 Grit's distortion tone is likened to a 386 IC amp, similar to the sound of tiny battery-powered guitar amps like the Lil Smoky.
Source -
The Erica/Game Changer Plasma module is described as unique and visually striking, although it may be more of an all-or-nothing effect, similar to other extreme distortion options.
