If 3 Were 6
With six times the controls found on the 1 and 2 versions (if you discount the original’s on/off slider switch,) the LPB-3’s control complement offers pre-gain, boost, mid freq, bass, treble, and mid knobs, with a center detent on the latter three so you can find the midpoint easily. A mini-toggle labeled “max” selects between 20 dB and 33 dB of maximum gain, and another labeled “Q” flips the resonance of the mid EQ between high and low. Obviously, this represents a significant expansion of the LPB’s capabilities.
More than just a booster with a passive tone, the LPB-3 boasts a genuine active EQ stage plus parametric midrange section, comprising the two knobs with shaded legends, mid freq and mid level. The gain stages have also been reimagined to include a pre-gain stage before the EQ, which enables up to 20 dB of input gain. The boost stage that follows the EQ is essentially a level control with gain to allow for up to 33 dB of gain through the LPB-3 when the “max” mini toggle is set to 33dB
A slider switch accessible inside the pedal selects between buffered or true bypass for the hard-latch footswitch. An AC adapter is included, which supplies 200mA of DC at 9.6 volts to the center-negative power input, and EHX specifies that nothing supplying less than 120mA or more than 12 volts should be used. There’s no space for an internal battery.
Power-Boosted
The LPB-3 reveals boatloads of range that betters many linear boosts on the market. There’s lots of tone-shaping power here. Uncolored boost is available when you want it, and the preamp gain knob colors and fattens your signal as you crank it up—even before you tap into the massive flexibility in the EQ stage.

I found the two mid controls work best when used judiciously, and my guitars and amps preferred subtle changes pretty close to the midpoint on each. However, there are still tremendous variations in your mid boost (or scoop, for that matter) within just 15 or 20 percent range in either direction from the center detent. Pushing the boost and pre-gain too far, particularly with the 33 dB setting engaged, can lead to some harsh sounds, but they are easy to avoid and might even be desirable for some users that like to work at more creative extremes.
The Verdict
The new LPB-3 has much, much more range than its predecessors, providing flexible preamp, boost, and overdrive sounds that can be reshaped in significant ways via the powerful EQ. It gives precise tone-tuning flexibility to sticklers that like to match a guitar and amp to a song in a very precise way, but also opens up more radical paths for experimentalists. That it does all this at a $129 price is beyond reasonable.

DOD says the Chthonic Fuzz is voiced for low-output pickups, and it’s easy to see how its gain structure and tone profile would work in that scheme. A quieter guitar leaves more headroom for more gain from your fuzz, and you can crank the fuzz here while operating your guitar wide open, too. The lower overall output volume, incidentally, did not push my amps in a way that left me wanting. It isn’t exclusively for low output pickups, either. A SG and Fender Tremolux turned up to eight sounded colossal, if a little toppy. If you’re looking for tonal reference, a 3-knob Tone Bender nudged to its bassier side and running at lower output volume is a close match. It’s grindier in the midrange than a Fuzz Face, and has little of a Big Muff’s low-end thunk or raw horsepower. What’s awesome about the Chthonic Fuzz is that I didn’t find many obvious parallels, and it’s really nice to try a new restaurant every once in a while.
The Treminator’s basic voice is satisfying and, at times, quite intoxicating and enveloping. The waveforms include very nice triangle and square shapes that yield pretty traditional tremolo sounds. There are also ramp-up and ramp-down forms that lend a slippery, mysterious air and suggest reverse tape effects. A random waveform evokes fractured, distant radio broadcasts and tape warble at some settings. The fade control unlocks even more textures by fading modulations in and out or enabling envelope-controlled speed ramping capabilities. And the super-useful LFO waveform reset mode restarts a waveform when the envelope reaches its threshold—eliminating the tug of war between irregular strumming patterns and wave pulses that creates messy rhythmic tangles.
The breadth of Treminator’s possible sounds goes well beyond those described here. Surprises abound. And its ability to reshape a tired riff—or guide you down unexpected musical paths—gives the Treminator immense potential as a compositional device.
