The Boomerang E-155 Chorus-Delay is a dual-function pedal that puts a chorus and a delay in one box. Rather than treating them as two separate effects, Boomerang built the E-155 around presets: the chorus and delay are combined in eleven factory presets, and you can create your own combinations and save them as eleven custom presets, all recalled from a two-button footswitch system1. Premier Guitar reviewed it in March 2021 at a street price of $3891.
The chorus section: Classic, Shimmer and Lush
The chorus side of the E-155 runs in three modes: Classic, Shimmer and Lush1. In Classic mode, the Mix pot controls chorus delay rather than effect level, so the knob works differently from the wet/dry blend most chorus players expect1.
Stereo operation and the Air Mix input
The E-155 offers stereo ins and outs1. It also has an "Air Mix" input, which gives the pedal a dry output to one amp, a useful feature in a two-amp rig where you want one amplifier to carry the unaffected signal1.
Expression control
The pedal accepts just about any passive volume pedal for expression, with no mono jacks required, though an expression pedal is not included1. Premier Guitar's reviewer used one to morph between presets, for example moving from a slow to a fast Leslie-style sound1. If you are shopping for a controller, see Expression Pedals and Volume Pedals.
What reviewers said
Premier Guitar's reviewer came away impressed by how little the pedal colored the core tone1:
"I heard no noticeable masking of frequencies or mid-range humps that change the core of my sound, just incredibly transparent effects."
The same reviewer found the fidelity of the sound was not changed by the circuitry, and noted there was no mid-range honk when the pedal was combined with overdrive1. On build quality: "The overall build of the E-155 is sturdy and well thought out," with an enclosure the reviewer described as built to last a long time1.

Questions
What does the Boomerang E-155 do?
It is a dual-function pedal from Boomerang that combines a chorus and a delay in one enclosure. The two effects are combined in eleven factory presets, or you can build your own and store them as eleven custom presets, all recalled from a two-button footswitch system. It runs stereo ins and outs and takes an expression pedal for morphing between presets.
How many presets does the E-155 have?
Eleven factory presets and eleven custom presets, for twenty-two in total. The chorus and delay effects are combined in the factory presets, and you can create your own combinations and save them to the custom slots. Presets are recalled from a two-button footswitch system on the pedal itself.
Can I use an expression pedal with the Boomerang E-155?
Yes. Boomerang designed the E-155 to accept just about any passive volume pedal for expression, with no mono jacks required. An expression pedal is not included with the unit. Rocking the pedal can morph between presets, for example moving from a slow to a fast Leslie-style sound.
Is the Boomerang E-155 stereo?
Yes, the E-155 offers stereo inputs and stereo outputs. It also has an Air Mix input, which gives the pedal a dry output to one amp, useful in a two-amp setup where you want one amp to carry the unaffected signal.
What does the Mix knob do on the E-155?
It depends on the chorus mode. In Classic chorus mode, the Mix pot controls chorus delay rather than effect level, which is a departure from the usual wet/dry blend found on most chorus pedals.
What are the Classic, Shimmer and Lush modes?
The E-155's chorus section runs in three modes: Classic, Shimmer and Lush. In Classic mode, the Mix pot controls chorus delay rather than effect level. The modes give the chorus section three distinct characters that can be combined with the delay in the pedal's presets.
