The PCB Mania Self-Build Harmonic Stimulant is a hand-built effect based on the classic Systech Harmonic Energizer circuit. Designed as a clone of the original unit, it delivers a distinctive harmonic enhancement effect that combines elements of EQ, boost, and subtle modulation to create a lively, resonant tone character.
The Harmonic Stimulant is known for adding upper harmonic content and focused midrange presence, making it particularly effective for cutting through a mix. Depending on the settings, it can range from a bright, almost vocal-like emphasis to a more aggressive, synth-like coloration. This makes it suitable for experimental textures, pronounced lead tones, or enhancing already driven amplifiers.
Typical controls include level and filter-related parameters that shape the frequency focus and intensity of the harmonic emphasis. The result is a dynamic and interactive response that reacts clearly to picking attack and instrument volume adjustments.
As a self-build unit based on a PCB Mania layout, this pedal offers boutique-style character in a unique, DIY-built format. Ideal for players seeking uncommon and characterful tone-shaping tools inspired by vintage circuitry. DIY build; no warranty!
