A growing collection of custom guitar effects for the Polyend Endless pedal. Every effect includes prebuilt .endl binaries — just download and copy to your pedal via USB. Source code included for tweaking and learning.
Built with the Polyend FxPatch SDK for the ARM Cortex-M7 platform.
| Effect | Type | Description |
|---|---|---|
| Tremvolope | Tremolo | Envelope-controlled stereo tremolo. Your playing dynamics shape the rate, depth, and stereo spread — quiet signals bloom into swirling modulation, or loud attacks drive aggressive throb. Inspired by the EHX Super Pulsar. |
| Preamp | Boost / Preamp | Transparent preamp and clean boost with tanh soft saturation and tilt EQ. Adds warmth and compression without coloring your tone. Use as an always-on foundation or to push your amp. |
| Necessary Delay | Delay / Reverb | BBD-style bucket-brigade delay into spring reverb. Vibrato-wobbled, progressively darkening repeats dissolve into dripping, metallic ambience. Hold the footswitch for infinite sustain, drones, and layering. |
