The Way Huge Smalls Conspiracy Theory Professional Overdrive is a compact overdrive pedal from Way Huge, first shown in April 20191. It is built as a take on the Klon Centaur circuit: Guitar World's reviewer Paul Riario described it as "yet another type of 'Klones' overdrive"2, and GuitarPlayer's buying guide called it "an on-the-nose take on the Klon clone"3. Way Huge's own description of what it does is that it "infuses your guitar signal with rich harmonics for smooth, transparent overdrive"4.
It sits in Way Huge's Smalls series, the reduced-size enclosure line the brand uses for its compact pedals. Guitar World noted that "its reduced size is small enough to be concealed on your person," and it ships in a copper-orange housing with red control knobs2. Delicious Audio reported it as a brand new Klone with increased headroom for a dynamic, wide open sound5.
A smooth, transparent overdrive in the Klon tradition
The Klon Centaur is the circuit this pedal is measured against, and the press has been consistent about the family resemblance. Guitar World's review placed it squarely among the Klones2, GuitarPlayer's best-Klon-clones guide listed it alongside the pedals of that type3, and Guitar Pedal X's roundup of Klon-style pedals noted it comes "in the recent Smalls compact enclosure"7. Delicious Audio introduced it in July 2019 as a brand new Klone5.
What Way Huge says the circuit does is bond rich harmonics with the guitar signal for a smooth, transparent overdrive4. Delicious Audio's launch coverage added that the pedal has increased headroom, which points to the same quality players look for in this circuit family: a drive that pushes an amp without smothering the guitar's own character5.
Guitar World's Paul Riario, reviewing it in November 2019, went further than most reviewers do with a Klon-style pedal2:
"this time around, I'm willing to admit it's pretty darn close"
Paul Riario, Guitar World2
His review described it as a full-bodied and rich overdrive pedal, and his verdict on closeness to the original Klon is the strongest published judgment the pedal has received2.
The controls: Gain, Output and Treble
The Conspiracy Theory keeps to three knobs, the same control set as the circuit it draws from. Guitar World listed them as Output, Treble and Gain2, and GuitarPlayer's buying guide summarized the pedal as three controls3.
| Control | What it does |
|---|---|
| Gain | Way Huge says adjusting it bonds rich harmonics with the guitar signal to create the smooth, transparent overdrive4 |
| Output | Sets the output level2 |
| Treble | Shapes the signal along with the Volume control4 |
In Sweetwater's demo video, the presenter found that even with the simple three-knob setup the pedal has a great range, with all three knobs usable across their full range and no dead spots8.
Using it as a clean boost
The Gain and Output controls also cover boost duties. In the Sweetwater demo, the presenter's advice was direct8:
"if you just want a clean boost you know turn the turn the gain down turn the output up"8
Sweetwater demo video8
Combined with the increased headroom Delicious Audio reported5, that makes the pedal usable as a level boost into an already-driven amp, the way many players use Klon-style circuits.
Power: 9V battery or adapter
Way Huge gives the pedal several power options. It can run on a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Brick, Iso-Brick and Mini Iso-Brick power supplies, which are not included4. GuitarPlayer's buying guide lists it as 9V DC only3, so a player building a powered board will be on adapter supply rather than a battery long term. The Sweetwater demo also noted a very low current draw, though no milliamp figure was given8.
The DC Brick, Iso-Brick and Mini Iso-Brick power supplies Way Huge names as compatible are sold separately, not included with the pedal4.
The Deep State Conspiracy Theory variant
Way Huge also makes a modified version, the Smalls Deep State Conspiracy Theory Diodes Overdrive. Way Huge describes it as a modified version of the Conspiracy Theory Overdrive in which special diodes with a particular voltage drop were implanted into the circuit, producing "smooth, velvety clipping that responds to playing dynamics like you wouldn't believe"6. RockBoard's listing for the pedal gives its power as 9V DC, center negative9.
The Deep State was designed in collaboration with Joe Bonamassa, and Way Huge says it can only be found exclusively at Joe's Reverb store6. Where the standard Conspiracy Theory is a general-release Klon-style overdrive, the Deep State is a limited-channel variant with a different clipping character.
Where it sits among Way Huge overdrives
The Smalls line holds several other Way Huge drives, including the Smalls Red Llama Overdrive, the Smalls Green Rhino Overdrive MKV, the Smalls Supa-Lead and the Smalls Pork & Pickle. Pedal of the Day, reviewing the Smalls Supa-Lead in 2020, described it as "one of a different flavor from the Klon-based Conspiracy Theory," which is a useful marker: within the Smalls range, the Conspiracy Theory is the Klon-style entry, and the other drives take different approaches10.

Questions
Is the Way Huge Conspiracy Theory a Klon clone?
Yes, by most accounts. Guitar World's reviewer called it another entry in the family of Klon-style overdrives, and GuitarPlayer described it as an on-the-nose take on the Klon clone. Guitar World's Paul Riario found it pretty darn close to the real thing, which is about as far as a reviewer goes with a circuit of this type.
Can the Conspiracy Theory be used as a clean boost?
Yes. In Sweetwater's demo video, the presenter's advice for a clean boost was to turn the gain down and the output up. The pedal also has increased headroom for a dynamic, wide open sound, which helps when running it as a level boost rather than a drive.
Does the Way Huge Conspiracy Theory take a battery?
Yes. Way Huge says it can be powered by a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Brick, Iso-Brick and Mini Iso-Brick power supplies, which are sold separately. GuitarPlayer's buying guide lists it as 9V DC only, so adapter power is the practical option for a permanent board.
What is the difference between the Conspiracy Theory and the Deep State Conspiracy Theory?
The Smalls Deep State Conspiracy Theory Diodes Overdrive is a modified version of the Conspiracy Theory. Way Huge says special diodes with a particular voltage drop were implanted into the Conspiracy Theory circuit, producing smooth, velvety clipping that responds to playing dynamics. It was designed in collaboration with Joe Bonamassa and is sold exclusively at Joe's Reverb store.
