The Inflection Point is a tremolo and vibrato pedal from boutique builder Mattoverse Electronics, listed at a $199 street price1. A small toggle on the pedal selects between tremolo and vibrato mode, and since it is a toggle rather than a footswitch, you must stoop to change modes1. The pedal occupies a standard BB-sized enclosure and runs on standard 9-volt power1.
The core of the sound is a classic optical circuit. Premier Guitar's reviewer found that a large, 5 mm LED shines onto a light-dependent resistor, and turning the rate and depth knobs alters the brightness and pulsation speed of that LED, which determines the rate and intensity of the effect1. Beyond the expected tremolo and vibrato, the reviewer found you can create basic chorus sounds and even a quasi-reverb ambient effect1.
Eight waveforms and two modes
The Inflection Point offers eight user-selectable waveforms, including two Random settings3. The two press outlets describe the waveform sets slightly differently:
| Source | Waveforms listed |
|---|---|
| Guitar Pedal X4 | Ramp Up, Ramp Down, Square, Triangle, Sine, Lumps, Stepped, Random |
| Premier Guitar1 | Triangle, sine, square, two sawtooth (ramp up and ramp down), sweep, random slope, random pulse |
A small toggle on the enclosure selects tremolo or vibrato mode3. Premier Guitar's reviewer noted one practical drawback: because the selector is a small toggle rather than a footswitch, you must stoop to change modes mid-performance1.
The controls, switches and sync input
Guitar Pedal X lists the full control set4:
| Control | What it does |
|---|---|
| Depth | Sets modulation intensity, by altering the LED brightness14 |
| Rate | Sets modulation speed, by altering the LED pulsation speed14 |
| Space | Adds resonant ambience34 |
| Waveform | Selects Ramp Up, Ramp Down, Square, Triangle, Sine, Lumps, Stepped or Random4 |
| Dry/Wet | Blends the effect with the dry signal14 |
| Output/Boost | Sets output level, usable as a clean boost34 |
| Mode toggle | Chooses tremolo or vibrato3 |
| Bypass footswitch | True bypass switching34 |
| Tap tempo footswitch | Sets the rate in real time14 |
Premier Guitar highlighted the wet/dry blend and the dedicated tap-tempo footswitch among the pedal's pros1.
The Space knob
The Space control is the unusual one. Mattoverse describes it simply as adding resonant ambience3. Premier Guitar's reviewer explained what is behind it:
"One unexpected feature is a 'space' control, which adds a PT2399 digital delay chip to the circuit1."
The regeneration is short and dense, adding subtle ambience rather than a full delay or reverb. There are no speed or feedback controls, just a single "more" knob1.
The sync input
The pedal's synth influence shows in its 1/8" sync-input jack, which accepts external clocks and sequencers. When a sync signal is present, the speed knob is disabled and the pedal follows the incoming clock instead1. Premier Guitar listed the input jack for external sync among the pedal's pros1.
Analog, digital or hybrid?
The Inflection Point is an analog/digital hybrid. The modulation is the analog optical LED-and-LDR circuit described above, but the pedal also incorporates two modern PIC (programmable intelligent computer) chips, with a Druid Stomp LFO generating the multiple waveforms1. The Space control adds a PT2399 digital delay chip1. So the tremolo and vibrato character is analog, while the waveform generation and ambience are digital.
Versions and availability
Mattoverse introduced a compact-size version of the Inflection Point in December 2020, identical to the original but in a smaller case3. The maker says the circuit is the same regardless of enclosure size, except that the CV Gate Rate Sync feature is not standard on the new smaller model3.
As of October 2026 the maker's product page lists the Inflection Point as sold out3. If you are shopping for one, the compact version's lack of standard CV Gate Rate Sync is the one functional difference to be aware of3.
What reviewers said
Premier Guitar's 2021 review was positive on the pedal's core strengths, listing as pros the nice optical vibrato and tremolo, the eight waveform options, tap tempo, the wet/dry blend and the input jack for external sync. Its cons were the lack of a stereo output and the absence of a battery compartment1.
Guitar Pedal X's Stefan Karlsson reviewed it in September 2024 as a "really smart 4-in-1" multi-FX, covering the tremolo, vibrato/chorus, reverb and boost functions at a £199/$199 price4.

Questions
Does the Mattoverse Inflection Point run on a battery?
No. The pedal runs on standard 9-volt power and does not include a battery compartment, so you will need a power supply. Mattoverse does not list a battery option on its product page either.
Is the Mattoverse Inflection Point stereo?
No. Premier Guitar's review lists the lack of a stereo output among the pedal's cons, so the Inflection Point is a mono in, mono out pedal.
Is the Inflection Point analog or digital?
It is an analog/digital hybrid. The modulation itself is a classic optical circuit, a large 5 mm LED shining onto a light-dependent resistor, while two PIC chips and a Druid Stomp LFO generate the waveforms and a PT2399 chip handles the Space ambience.
What does the Space knob on the Inflection Point do?
It adds resonant ambience. Premier Guitar describes it as adding a PT2399 digital delay chip to the circuit, with short, dense regeneration for subtle ambience. There are no speed or feedback controls, just a single more knob.
Is the Mattoverse Inflection Point discontinued?
As of October 2026 the maker's product page lists it as sold out. A compact version was introduced in December 2020 with the same circuit, though the CV Gate Rate Sync feature is not standard on the smaller enclosure.
