Wampler Euphoria

The Wampler Euphoria is an overdrive pedal made by Wampler, built in the USA and designed by Brian Wampler as his take on the tone and feel made famous by Dumble-style amplifiers¹. Wampler describes its sound as "smooth creaminess yet crunchy," and the pedal offers three clipping modes, Smooth, Open and Crunch, chosen with a toggle switch¹². It sells for $199.97 on Wampler's product page as of August 2026¹.

The pedal began life under the name Ecstasy before being renamed Euphoria, and it has become, in Delicious Audio's words, "famous for its versatility and that old boutique catch phrase 'transparency'"².

What it is and where it came from

The Euphoria is Wampler's D-style overdrive. Wampler's own product page frames it directly: "The Euphoria is my take on that elusive tone and feel made famous by 'Dumble style Amplifiers'"¹. Delicious Audio likewise calls it "a popular pedal inspired to the Dumble Overdrive amps (aka D-Style)"². Pedal of the Day's 2014 review adds that it is "based in part off of the tone of D-Style Amplifiers," while noting that the circuitry itself is completely original rather than a copy³.

The circuit predates the name. Delicious Audio reports that when Brian Wampler created the circuit that would eventually become the Euphoria, he was working on a pedal aimed at that Dumble-style territory². The pedal first appeared as the Ecstasy. Pedal of the Day explains the rename: "The Wampler Euphoria (formerly the Ecstacy, but the good people at Bogner took ex[ception]" to the name, since Bogner builds an amplifier called the Ecstasy⁴. Tone Island's buying guide confirms the pedal "started out under a different name, Ecstasy"⁵. Strymon's documentation on two-stage overdrive circuits lists the "Wampler Ecstasy/Euphoria" among its examples of the configuration⁶.

The current version is the V2, which moves the jacks to the top of the enclosure; Wampler's page quotes a player who prefers that layout¹. The pedal comes in a dark green metallic case and is handbuilt in the USA, in Martinsville, Indiana³⁴.

The controls

The Euphoria has four knobs: Volume, Gain, Bass and Treble¹. Delicious Audio's V2 description lists the same set as Gain, Volume, Bass and Tone, with the Bass functioning pre-gain⁷.

A three-position toggle selects between the three clipping styles, Smooth, Open and Crunch¹². Wampler describes Smooth as "a warm 'D' style overdrive, fat and rich, powerful with a strong sustain"¹, and Delicious Audio characterizes it as "low-gain, with just enough sustain to make notes sing"².

The feature both Wampler and the press single out is the pre-gain bass control. Wampler calls it "the hidden secret of the Euphoria"¹, and Delicious Audio explains what it does for a player: the Bass knob functions pre-gain, "allowing you to dial in low-end that sounds thick, without muddying up your tone," a fatness "that a regular EQ stack can't" give you². Because the bass is shaped before the clipping stage rather than after it, the character of the drive changes along with the low-end setting.

Pedal of the Day's 2014 review found the rest of the panel straightforward: "The Volume, Tone and Gain controls do what you would expect"³.

Power: 9V or 18V, 8 to 15mA

The Euphoria runs on a 9V power jack with a barrel plug like a Boss pedal, and it also runs at 18V¹³. It has a battery connection as well¹⁴. Power draw is between 8mA at 9V and 15mA at 18V¹; Pedal of the Day's earlier review listed the same 8mA figure at 9V⁴.

At 8 to 15mA the pedal is a light load, well within what a standard 9V power supply or an isolated output on a pedalboard power brick delivers. The 18V option gives the headroom a player might want for cleaner, louder settings¹⁴.

What reviewers said

Pedal of the Day reviewed the pedal twice, in 2014 and again in 2015. The 2014 review called it "an extremely versatile overdrive pedal that pushes well into distortion-pedal space before it's done," and found it doubles as a clean boost³⁴:

The same review described the overall character as versatile, warm, creamy and crunchy, and a great clean boost³. The 2015 review noted that Wampler promotes the pedal as their "Dumble Box" and confirmed the completely original circuitry and completely true bypass⁴. Delicious Audio's coverage of the V2 echoes the versatility point, calling the pedal famous for its versatility and transparency².

Where it sits among Wampler overdrives

The Euphoria is Wampler's D-style entry in a range that covers several other amp-inspired drives, including the Wampler Pantheon (Bluesbreaker territory), the Wampler Plexi-Drive (Marshall), the Wampler Black '65 (Fender blackface) and the Wampler Tumnus Germanium (Klon). A player comparing Dumble-style options will also find it listed alongside other D-inspired pedals in buying guides from Delicious Audio and Tone Island⁷⁵.
