The Electro-Harmonix Tone Corset is an analog compressor stompbox 1. It sits in the company's compressor line alongside the Soul Preacher, the Platform Stereo Compressor and the Pico Platform.
The controls: Volume, Attack, Sustain and Blend
The Tone Corset keeps things simple: four knobs laid out, as gearnews.com put it, "in a very logical manner" 5.
| Control | What it does |
|---|---|
| Sustain | Controls the amount of the compression 1 |
| Attack | Controls how quickly the compressor will recover 1 |
| Blend | Adjusts the mix of the dry and compressed signal set to the output 1 |
| Volume | Output level 5 |
| Pad switch | Pads down the input signal to prevent undesirable distortion 1 |
The Blend knob is the feature that sets the pedal apart from a basic two-knob compressor. Electro-Harmonix calls it "a blend control to dial in the purfect amount of parallel compression" 1, and MusicRadar's reviewer Trevor Curwen described it the same way: "a Blend knob sets up parallel compression" 7. Parallel compression means a fully compressed copy of your signal is mixed back in with the untouched dry signal, so you get sustain and evenness without losing the attack and dynamics of your playing. gearnews.com's writer explained the practical benefit: "Having a Blend control essentially allows you to retain the dynamics of your guitar signal and still keep your signal under control" 5.
The Pad switch matters if your guitar runs hot. It attenuates the input so the pedal does not overload into distortion when used with higher output pickups like humbuckers or active bass pickups 5. MusicRadar's launch coverage highlighted the same two features: the "analogue stompbox packs blend knob and pad switch" 6.
What reviewers said
Mike Matthews, Electro-Harmonix's founder, put it plainly on the product page: "The Tone Corset is the funkiest analog compressor I ever heard on guitar!" 1.
MusicRadar's review, by Trevor Curwen, summed the pedal up as "A pedalboard-friendly compressor with a good mix of options that complements guitar sound" 7. gearnews.com's writer liked the simplicity of the design: "I love the simple layout and think it has all most of us would ever need from a compressor without overloading us with options" 5.
For players comparing it within the Electro-Harmonix range, the Tone Corset is the analog, four-knob option; the Platform and Pico Platform cover stereo and mini digital compressor territory, and the White Finger and Black Finger are the company's optical and tube-based compressors.

Questions
Is the Electro-Harmonix Tone Corset analog?
Yes. Electro-Harmonix lists it as an analog compressor, and it is built around an OTA (Operational Transconductance Amplifier) circuit. It was introduced in June 2017 as a compact analog stompbox, sitting alongside the company's other compressor designs such as the Soul Preacher and the Platform.
What does the Blend knob do on the Tone Corset?
The Blend knob adjusts the mix of dry and compressed signal sent to the output, setting up parallel compression. That lets you retain the dynamics of your guitar signal while still keeping the overall level under control, so the compressed part of the sound can work without flattening everything you play.
What does the Pad switch do on the Tone Corset?
The Pad switch pads down the input signal to prevent undesirable distortion. gearnews.com's writer noted it stops the pedal overloading into distortion when used with higher output pickups such as humbuckers or active bass pickups.
How much does the Tone Corset cost?
Electro-Harmonix's own product pages listed the Tone Corset at $103.40 USD as of October 2026. At its June 2017 introduction, gearnews.com reported an RRP of USD 119.30.
Does the Tone Corset work with high-output pickups?
Yes, that is what the Pad switch is for. It attenuates the input signal so the pedal does not overload into distortion with higher output pickups like humbuckers or active bass pickups, according to both Electro-Harmonix and gearnews.com's coverage of the launch.
