The Mad Professor Tiny Orange Phaser is a phaser pedal made in Finland by Mad Professor, a maker whose bass line also includes the Blueberry Bass Overdrive and the Snow White Bass Auto Wah1. It carries an MSRP of $3982.
What it does
A phaser splits your signal and shifts the phase of one copy against the other, producing the moving, sweeping character associated with the effect. The Tiny Orange Phaser's voicing is what sets it apart: Premier Guitar's reviewer found it midrange-focused, which gives the effect more cutting power in a mix1. That focus comes with a trade-off the reviewer flagged for players who want more from a phaser:
"if you're looking for a greater range of tonal versatility, you'll definitely want to test this before purchasing."
The enclosure holds three white knobs atop a shimmering orange body1. The Speed knob sets the rate of the phase effect, with a range the reviewer called respectable: slow and floating at its leftmost point, and shimmery vibrato at its rightmost. The manual suggests parking the knob at noon for "classic" phase sounds, a spot the reviewer found to be a common stopping point1.
| Control | What it does |
|---|---|
| Speed | Sets the speed of the phase effect, from slow and floating fully counterclockwise to shimmery vibrato fully clockwise; the manual suggests noon for "classic" phase sounds1 |
What reviewers said
Premier Guitar's review framed the pedal as a nuanced effect for adding movement to your signal, and its verdict came down to what a player wants from a phaser: buy it if you want that nuanced movement, and skip it if you do not1. For bass players building a board, the midrange-focused voicing is the thing to weigh, since it shapes where the effect sits against the low end1.
