Module tolerance 

Component tolerance randomization.

Real resistors and capacitors are ±5–20% from their nominal values. Two identical pedals sound slightly different because of this.

This module provides a seeded pseudo-random tolerance system:

• Each “unit” (physical pedal instance) gets a seed
• Component values are deterministically varied from nominal
• A saved preset always sounds like the same physical pedal
• Two instances of the same model diverge slightly

The randomization uses a simple but deterministic hash-based approach so that the same seed + component index always produces the same offset.
