FX Mini

Drive, tone, and bounded feedback delay.

What it does

A compact pedal chain for a mono signal: drive into a tone filter into a feedback delay. It is the classic starter pedalboard in one small panel, and a simple, readable example of a complete effect.

The idea

The order is fixed and nothing is hidden between the stages. The tone filter sits after the drive, because that is where a tone control does the most work: it shapes the harmonics the drive has just created, rather than filtering the input before they exist. The delay comes last, so the repeats carry the driven, filtered sound.

Guide and controls

How it works.

The chain is distortion into a tone filter into a feedback delay, in that order and with nothing hidden between the stages. The drive stage is a waveshaper with its own wet/dry mix, so you can blend saturated signal under the clean one rather than committing to it.

Tone is a biquad low-pass sweeping 200 Hz to 8 kHz, placed after the distortion because that is where a tone control does the most work - filtering harmonics the drive stage just generated, rather than filtering the input before they exist.

The delay is single-tap with feedback capped at 0.9. That cap is deliberate: the delay will self-oscillate and sing at the top of its range, but it cannot run away and damage your monitoring. This is the same kernel the offline batch renderer uses, so a render matches what you hear here.
