The T-Rex Sweeper 2 is a chorus pedal made by T-Rex Engineering, with a street price of $1991. It comes in a purple enclosure with the jacks mounted at the top1, and Premier Guitar's reviewer summed up the build as "Solid construction. Thoughtful layout."1
What it does to your sound
The Sweeper 2 is a chorus: it doubles your signal with a modulated copy to produce width and movement. T-Rex describes the pedal as an analog sounding chorus, and the circuit behind it is a digital core that the company upgraded for the second version, aimed at a warmer vintage sound2. Premier Guitar's reviewer put it the same way: T-Rex "adjusted the digital core's algorithm to produce warmer, more vintage-sounding modulation"1.
"The Sweeper 2 chorus gives bassists easier-to-read control graphics and an upgraded algorithm."
Controls and layout
The pedal carries five controls: on/off, depth, rate, volume and input gain2. The depth, rate and volume knobs sit in the same arrangement as the original Sweeper1. The input gain control is the one aimed at bass players' differing signal levels: it is mounted on the side of the pedal, with an LED clipping indicator for setting your level, and the knob can be pressed into the enclosure so it cannot be knocked accidentally1.
| Control | What it does |
|---|---|
| Depth | Amount of modulation |
| Rate | Speed of the modulation |
| Volume | Output level |
| Input gain | Input level, side-mounted, with LED clipping indicator |
| On/off | Bypass switching |
The maximum input signal is adjustable (given in V p-p on the maker's page), which is how the pedal accepts both bass and guitar levels2.
Stereo outputs and connections
The Sweeper 2 has L and R outputs for stereo operation, and it works in mono too if you only use one output4. The enclosure is purple, with the jacks mounted at the top, which keeps the pedalboard footprint tidy1.
How it differs from the original Sweeper
Beyond the algorithm change, Premier Guitar's reviewer found the Sweeper 2 has the same features as the previous version, so the upgrade is mainly about the voicing of the modulation and the refreshed graphics rather than a new control set13.
What reviewers said
Premier Guitar's review of the pedal praised the build: the reviewer summed up the construction and layout as "Solid construction. Thoughtful layout," describing a well-built pedal with rugged hardware and an expertly installed circuit board1.

Questions
Is the T-Rex Sweeper 2 analog or digital?
The Sweeper 2 uses a digital core that T-Rex voices to sound analog. The maker describes it as an analog sounding chorus, and the Sweeper 2's main upgrade over the original Sweeper was an adjustment to the digital core's algorithm, which Premier Guitar's reviewer found produced warmer, more vintage-sounding modulation.
Does the Sweeper 2 Bass Chorus have stereo outputs?
Yes. The pedal has L and R outputs for stereo operation, though it can also be used in mono with a single output. Premier Guitar noted the dual outputs as one of the pedal's features in its review.
What does the input level knob on the Sweeper 2 do?
The input gain control is mounted on the side of the pedal and sets the level going into the chorus circuit. It includes an LED clipping indicator to help you dial in the level, and the knob can be pressed into the enclosure to prevent accidental changes.
Can the Sweeper 2 be used with guitar?
Yes. T-Rex describes the Sweeper 2 as classic chorus for bass guitar, but the pedal is made for bass and guitar, and the adjustable maximum input signal means it can accept a range of instrument levels.
