The AllPedal Slamurai is an overdrive pedal with a built-in 3-band EQ, made by AllPedal in Paducah, Kentucky, USA. AllPedal describes it as an attempt to build "the most amp-like and versatile overdrive available," with a range that runs from clean boost all the way up to more modern drive tones1.
What sets it apart from most overdrives is the EQ section. Alongside the drive circuit, the Slamurai carries a highly tunable 3-band EQ that AllPedal designed specifically for guitar, so you can shape bass, midrange and treble after the drive stage rather than working around a fixed tone stack1. Delicious Audio's Paolo De Gregorio summed up the circuit as one that "delivers rich, smooth overdrive that perfectly compliments a wide range of styles, genres and amplifiers"2.
What it does and how it sounds
AllPedal positions the Slamurai as an amp-like overdrive: the maker points to touch sensitivity, amp-like dynamics and harmonically rich textures, with the gain range stretching from a clean boost into modern drive territory1. The 3-band EQ is the shaping tool on top of that, tuned for guitar frequencies rather than a generic audio EQ1.
The enclosure is built for pedalboard use, with rugged construction, a metallic finish, embossed artwork and anodized knobs1. Delicious Audio also notes top-mounted jacks, which keep the pedal's footprint tight on a crowded board2.
Controls and connections
The control surface centers on the drive section and the 3-band EQ. AllPedal describes the EQ as "highly tunable," designed specifically for guitar1. The pedal uses a soft-touch footswitch and top-mounted jacks2.
| Control | What it does |
|---|---|
| Drive section | Sets the gain, from clean boost up to modern drive tones1 |
| 3-band EQ | Bass, mid and treble shaping, tuned for guitar1 |
Power and practical requirements
The Slamurai runs on external power only, and the maker's requirements are specific13:
- Voltage: 9V DC1
- Current draw: 14mA1
- Polarity: Center pin negative1
- Supply requirement: Fully regulated, delivering at least 20mA, such as the TrueTone 1 SPOT1
No power adapter is included, and there is no internal battery1. The pedal needs a fully regulated 9V DC supply with at least 20mA of headroom, so a shared or unregulated supply is not what AllPedal specifies.
At 14mA of draw, the pedal is light on a power brick's budget, but the maker's 20mA minimum for the supply is worth respecting when choosing a distributor13.
Versions and the DIY option
The Slamurai is available in more than one form. There is a Parlor Edition, the AllPedal Slamurai Overdrive Parlor Edition, which shares the same core design, power requirement and warranty terms3. Delicious Audio also lists the Slamurai as available either fully built or as a DIY kit, describing the kit as "an entry level boutique pedal kit that offers pro quality build, tone and performance for the DIY enthusiast at any skill level"2.
What reviewers said
Pedal of the Day reviewed the Slamurai in June 2023 and echoed the maker's framing, writing that "with the Slamurai™, All-Pedal set out to make the most amp-like and versatile overdrive available," and concluding that pairing it with three other All-Pedal pedals on one board would leave a player "ready for any musical situation"4.
Guitar Pedal X's Stefan Karlsson, writing about the related Slamurai Bushido Drive in May 2024, called it5:
"a fantastically versatile overdrive with 3-Band EQ also"
and noted he had been impressed with it overall5.
Price and warranty
AllPedal lists the Slamurai at a regular price of £199.00 GBP1. The pedal carries a 3 year warranty, with an upgrade path to a lifetime warranty offered at purchase1.

Questions

Is the AllPedal Slamurai true bypass?
Yes. AllPedal lists the Slamurai as true bypass, so with the pedal switched off your signal passes through without active buffering. That suits players who want the pedal out of the chain entirely when it is disengaged.
What power polarity does the Slamurai use?
It uses 9V DC with a center-pin-negative plug, the standard polarity for most guitar pedals. AllPedal calls for a fully regulated supply delivering at least 20mA, and the pedal itself draws 14mA. No adapter is included in the box.
