Allpedal Microdose Phaser

A modern optical phaser, blending vintage heritage with contemporary control

The phaser is one of the iconic effects that have marked pedalboards since the golden age of psychedelic and funk sounds, then 70s rock. The Microdose fits into this tradition thanks to a 100% analog audio path and an optical architecture that retains a soft, fluid, and very "alive" feel under the fingers.

Where many phasers remain confined to a single character, the Microdose aims for a more current approach: you keep the warmth and roundness of analog phasing, but with setup tools (Tap Tempo, speed multipliers) and a waveform selection that open up more experimental territories.

Who it's for: discerning guitarists, from subtle grooves to soaring soundscapes

The Allpedal Microdose is designed both for musicians who want an "always useful" phaser to thicken a clean tone and for fans of more creative modulation. In blues, funk, pop, indie, rock, and even more ambient contexts, it allows adding movement without crushing the attack or dynamics.

On stage, the Tap Tempo facilitates syncing to the song, and the Level control helps maintain consistent volume when switching from a dry sound to deeper phasing. In the studio, the Blend becomes a powerful tool to dose the effect's presence while preserving a clear foundation in the mix.

Settings and features: a phaser designed for tempo and precision

The Microdose offers a control section designed to finely sculpt the effect. Rate sets the LFO speed, while Depth adjusts the modulation amplitude: at low depth, you get a subtle vintage veil, and pushing it leads to more spectacular, almost "otherworldly" sweeps.

Res adds feedback (regeneration) to emphasize the notches and peaks of the phasing: perfect for more expressive sounds, or even downright excessive when you want the effect to take center stage. The Blend control mixes the original and modulated signals: ideal for a discreet and clear phaser, but also capable of going full wet for more radical textures that can evoke a pitch modulation sensation depending on the settings.

For rhythmic setup, the pedal combines Tap Tempo and a Multiplier selector (x0.5 / x1 / x1.5 / x2 / x3 / x4). This is extremely practical for switching from a slow, wide pulse to faster vibrations without re-tapping the tempo. Finally, the Waveform and Wave Set selectors provide access to 16 waveforms, from the classic smooth curve to more atypical movements, perfect for modernizing a traditional phaser.

An EXP input allows connecting an external expression pedal to control the Rate in real time: ideal for creating swells, slowdowns, and very musical transitions, both live and in recording.

The sound

The Microdose stands out with a warm and smooth signature, typical of well-designed analog modulations. At 2 stages, the movement is lighter and precise, ideal for adding a subtle shimmer to a strummed chord or a funk rhythm. At 4 stages, it offers a very versatile balance, with that "liquid" side that naturally complements playing.

At 8 stages, the phasing becomes deeper and broader: the notches are more pronounced, the sweeps wider, and the effect can truly transform a clean sound into a moving pad. With the Blend, you maintain control over attack clarity, which helps the Microdose stay usable on a modern pedalboard, even in front of overdrives or delays, without losing the feel of the playing.
