The Mattoverse HiLo Boost is a boost pedal from Mattoverse Electronics that does something most boosts do not: instead of one volume-style knob, it boosts low and high frequencies independently, with its own knob for each. Mattoverse says there is approximately 25dB of gain available for both the high and low frequencies, and describes the pedal as usable as a tone-shaping preamp, a boost, or an overdrive for small wattage amplifiers1.
Controls
The HiLo Boost keeps its control layout to two knobs, and each one shapes a different part of the spectrum rather than just the overall level1:
| Control | What it does |
|---|---|
| Left knob | Controls how much the low frequencies are boosted1 |
| Right knob | Controls the level of high frequency boost1 |
That split gives the pedal a shaping role as well as a lifting one. Cutting one knob and raising the other tilts the tone toward bass or treble, which is why Mattoverse also calls it a tone-shaping preamp2. It sits alongside other tone-shifting tools like preamp pedals and equalization pedals, though with only two bands it is far simpler than either.
Uses: boost, preamp, overdrive
Mattoverse's product page gives the pedal three roles: "Can be used as a tone shaping preamp, boost pedal, or overdrive for small wattage amplifiers."2
As a straight boost, the roughly 25dB per band is enough to push a signal well above unity1. As an overdrive, the idea is to drive a small-wattage amplifier's input harder and let the amp break up, rather than generating distortion in the pedal itself2. Players looking for pedal-generated dirt would look instead at overdrive pedals, distortion pedals or fuzz pedals.
Power and availability
The HiLo Boost runs on 9V DC power only, with a center-pin negative Boss style connector, and the adapter is not included1. There is no battery option listed, so a standard 9V DC adapter or a pedalboard power supply output is required.
The Custom Paint #036 version of the HiLo Boost was listed as sold out on the maker's site as of 26 October 20261. Mattoverse has offered the pedal in numbered custom paint editions, including Custom Paint #0372, so availability depends on the current run.
The pedal's price has moved over time: the launch price was $79.00 USD, and the listed price as of 26 October 2026 was $119.00 USD1.

Questions
Is the Mattoverse HiLo Boost true bypass?
Yes. Mattoverse Electronics lists the HiLo Boost as true bypass, so when the pedal is off, your guitar's signal passes through without the circuit loading it. That matters on a pedalboard where a boost may sit idle for long stretches of a set.
Does the Mattoverse HiLo Boost take a battery?
The maker's product page specifies 9V DC power only, in the center-pin negative Boss style, and does not list battery operation. Plan on a standard 9V DC adapter or an isolated pedalboard power supply output.
Does the HiLo Boost come with a power supply?
No. The product page notes that the adapter is not included, so you will need to supply your own 9V DC center-negative adapter or use a spare output on your pedalboard power supply.
Can the Mattoverse HiLo Boost be used as an overdrive?
Yes. Mattoverse describes it as usable as a tone-shaping preamp, a boost pedal, or an overdrive for small wattage amplifiers. Pushing a low-wattage amp's input with the HiLo's gain can drive it into overdrive.
Is the Mattoverse HiLo Boost still available?
As of 26 October 2026, the Custom Paint #036 version on the maker's site was listed as sold out. Mattoverse has offered the pedal in numbered custom paint runs, so availability changes from run to run.
