What it does
FB Phaser is a free analog-style phaser that started life inside Full Bucket's own instruments (Deputy Mark II, Nabla and ModulAir); the developer split it out into a standalone plugin "just for fun." It is modelled on the vintage phasers once used to thicken string machines.
- Stages: switch between 4 and 8 phaser stages, from a gentler sweep to a deeper, more pronounced notch pattern.
- Manual and Spread: Manual sets the centre frequency of the phaser; Spread sets how far apart the individual stages sit.
- Feedback: sets how much of the phased signal is fed back, for a sharper, more resonant sweep.
- LFO: Speed from 0 to 25 Hz with an optional sync to host tempo, Depth for the amount of sweep, and a choice of sine or triangle waveform.
- Stereo: sets the LFO phase offset between the channels (0 to 180 degrees) and their panning, for a wider moving image.
- Mix: blends the phased signal with the dry input, so it also works as a parallel effect.
- Light and simple: double-precision processing, very low CPU use, 10 preset slots and a resizable interface in the standard version; there is no MIDI CC control.
The current version is 2.0.2 (24 November 2024). It is a free download; the developer accepts donations.

When to use it
FB Phaser is the pick when you want a classic analog-style sweep for free, with the few controls such a unit needs and almost no CPU cost. Compared with PhaseMistress (Soundtoys), it has one phaser voice instead of many vintage styles and no rhythmic or envelope modulation, but it is quicker to set and costs nothing. Unlike ShaperBox 3 or LFO Tool, it does not draw custom modulation shapes; its LFO is only sine or triangle. It also differs from MicroShift, which widens with pitch-shifted delays rather than sweeping notches, so FB Phaser is the one that actually phases.
- Best for: classic phaser sweeps on string pads, electric pianos, synths and guitars, and strong, swirling effects with Feedback and 8 stages.
- Genres: synth-pop, disco, funk, psychedelic rock, ambient and electronic.
- Look elsewhere if: you want many phaser models, tempo-synced rhythmic patterns or envelope control; PhaseMistress goes further.
- Tip: for subtler movement, use 4 stages with low Feedback and turn Mix down; at high settings it gets intense quickly.
What producers say
There is little written about it, but what there is treats it as a solid, lightweight free phaser that leans towards strong effects.
- KVR users rate it 4 out of 5 from 1 review; the reviewer called it "great for really seasick phaser sounds" but preferred another free phaser for subtle work.
- Bedroom Producers Blog described it as "lightweight and easy to use," with CPU use low enough for many instances even on older computers.
