Overview: Allpedal Devils Triad OD/BST/REV/DEL
The Allpedal Devils Triad OD/BST/REV/DEL delivers a self-contained pedalboard for guitarists who want to cover a wide stylistic range with modern edge and functional flexibility. Centered around the signature sound of Jeff Loomis (Arch Enemy), this USA-built box fuses overdrive and clean boost with independent plate reverb and delay. Its configuration prioritizes routing options, practical stage use, and direct integration with amplifier effects loops.
Main Features and Controls
- Four-in-One Design: Includes overdrive, boost, emulated plate reverb, and delay.
- Bypassable Sections: Dedicated footswitches for overdrive, boost, and reverb/delay, each section can be activated independently or stacked.
- Overdrive Section: Gain, Tone, and Level controls offer adaptation for rhythm or lead with a precise EQ sweep, allowing finesse when run into both clean and saturated amps.
- Boost Section: Level knob provides a substantial volume push, especially useful for solos or tightening up amp response. It is tunable for subtler applications as well.
- Delay/Reverb Section:
- Delay: Level, Feedback, and Delay Time controls for warm, repeatable echoes, usable pre- or post-amp.
- Plate Reverb: Level, Tone, and Decay dials help find the range between subtle ambiance and atmospheric wash.
- Signal Routing: Mono input and output through two 6.3 mm jacks, enabling use both in front of amps or in effects loops (four-cable method recommended for versatility).
- Physical Specs: Sturdy enclosure (146 x 119 x 60 mm, 547 grams), stage-ready for live or studio use.
- Power: Runs on standard 9V DC center-negative supply (not included).
In-Use Impressions
Players using the Devils Triad praise its flexibility and musical character, especially for those chasing high-gain, articulate metal tones made popular by bands like Arch Enemy, In Flames, Nightwish, and Children of Bodom. Practicality shines through its true bypassable sections, letting you combine or isolate each effect. The overdrive circuit retains tightness and clarity even before already-warmed-up amps, while the boost brings instant authority and focus, particularly for solo passages.
Both delay and plate reverb effects inspire confidence in real-world settings. Controls offer straightforward access to a wide range from subtle depth for clean intros to dense layers for expressive lead work. The tone and decay adjustments on the reverb stand out for dialing in specific room-like or ethereal flavors.
The four-cable method, enabled by input/output configuration, means users can place time-based effects in an amp effects loop while keeping drive sections upfront. Many players prefer delay and reverb after the preamp for cleaner repeats and trails, while stacking overdrive and boost pre-amplifier for maximum dynamics and push.
Sonic Identity and Use Cases
- Signature Metal Tones: The synergy between the overdrive and boost matches Jeff Loomis's articulate riffing and saturated leads. The included leaflet even provides recommended settings for nailing Arch Enemy-style preamp textures.
- Adaptable for Various Guitars: The tone sweep on OD and reverb ensures compatibility with a range of pickups and amp voicings, as reported by users adjusting for different styles.
- Complete Rig Solution: Players highlight that with the Devils Triad, the essentials, drive, rhythm tightness, atmospheric delay, and reverb, are available without juggling multiple pedals. This makes it viable for compact boards, fly dates, or studio setups where minimal cabling and patching is preferred.
Build Quality and Practical Details
Machined in the USA, the Devils Triad feels robust at 547 grams, substantial enough to stay put during set changes but not bulky. The control layout is intuitive, with individual LEDs for each active section. Knobs are spaced for easy adjustment, even on cramped stages. Powering the pedal uses a standard center-negative supply, which integrates with most modern pedalboards out of the box (adapter not included).
Limitations and Considerations
- There is no true metal distortion or fuzz circuit, drive and boost are voiced for classic and modern overdrive, not extreme saturation on their own.
- While mono only, the stereo pedals crowd may miss spatial spread, though in-amp or FOH options can address this.
- At a retail price of $349, the all-in-one utility, American build, and signature element justify the cost for many, but single-function pedal users may hesitate.
Conclusion
For guitarists seeking a streamlined, performance-ready solution geared for articulate, aggressive modern tones, the Allpedal Devils Triad OD/BST/REV/DEL captures the essentials. Its modular, stackable approach serves both traditional pedalboard users and players embracing amp loop flexibility. With Jeff Loomis's fine-tuning, robust build, and thoughtful effect selection, it stands out as a pro-level hub for metal, progressive, and even ambient voices.

Very nice pedal: Three sounds (overdrive, boost, delay/reverb) stackable with bypass for adding or removing each effect.
It matches the sound of the band Arch Enemy; with Jeff's suggested settings in the leaflet for Arch Enemy-type tones.
The overdrive section works precisely even in front of an already distorted amp, and the booster gives an extra push for solos.
