The Wampler Moxie is a compact overdrive pedal from Wampler, designed by Brian Wampler as what the maker calls his "twisted take on a vintage 'screamer style' circuit"1. It is based on the Ibanez TS10 Tube Screamer, one of the most emulated overdrive circuits of all time, and runs on the same classic 4558 chip that powered the original1. Where a stock Tube Screamer gives you one mid-boosted voice, the Moxie adds two toggle switches: Voice, which reshapes the EQ, and Fat, which switches in a custom MOSFET clipping stage for more gain1.
Guitar.com described it at launch as offering "an additional pair of voicing options and an extra MOSFET clipping stage" over the original TS10, and noted that the Moxie is "no mere clone"2. Gearnews made the same point: "Though this version of the circuit is not a straight-up clone and offers a twist to the formula"3. It sits in a mini-format enclosure with top-mounted jacks, aimed at players who want Tube Screamer character without giving up much pedalboard space4.
A TS10 overdrive with two extra switches
The core signal path stays faithful to that design: the 4558 op-amp chip, which Wampler says enables the pedal "to scream with authentic woody tones"1. What separates the Moxie from a straight reissue is the pair of toggles. Delicious Audio counted the combinations: "By combining the Moxie's two toggles, this pedal offers 4 extremely useful but significantly different tones"6. So one mini pedal covers the traditional mid-humped TS sound, a more transparent voicing, a bolder higher-gain take, and both together.
The controls
The Moxie keeps the classic three-knob layout of Volume, Gain and Tone, then adds the two switches on top6.
| Control | What it does |
|---|---|
| Volume | Sets the output level6 |
| Gain | Sets the amount of overdrive6 |
| Tone | Sets the treble response6 |
| Voice switch | Changes the entire EQ of the design, boosting bass and treble while cutting midrange for a more transparent, robust tone1 |
| Fat switch | Adds an extra dimension of gain via a custom MOSFET clipping stage, altering the overdrive's compression and texture1 |
The Voice switch is the bigger departure from Tube Screamer tradition. Gearnews explained that "Voice adjusts the EQ, adding clarity and transparency with an alternative voice, offering more than just the traditional" mid-boosted Tubescreamer tone3. Guitar World reported that the switch "cuts some of the bits and boosts lows and highs for what Wampler promises is 'a much more natural sounding and brawny overdrive'"4.
The Fat switch works differently: rather than reshaping the EQ, it changes how the pedal clips. With the switch engaged, a custom-voiced MOSFET clipping stage comes into the circuit, which Gearnews said "adds more gain and gives the circuit a bolder tone"3. Wampler describes the result as reminiscent of a classic high-end boutique overdrive1.
Power and connections
The Moxie runs from a 9V DC power jack, and there is no battery connector inside, so an external supply is required1. It also accepts an 18-volt adapter, which Premier Guitar's buying guide notes is "for increased headroom"5. Current draw is modest: between 11mA at 9V and 16mA at 18V, low enough that it can share a daisy chain or a compact isolated supply with plenty of other pedals1.
The enclosure is a mini-pedal format with top-mounted jacks, which Guitar World noted "preserve precious space on your pedalboard"4. Wampler lists the footprint at 1.5" x 3.5" x 1.5" (38.1mm x 88.9mm x 38.1mm), with the height excluding knobs and switches1. Bypass is 3PDT true bypass, so the signal passes through untouched when the pedal is off1.
No battery option: the Moxie has a 9V power jack but no battery connector inside, so it needs a power supply from day one1.
What reviewers said
Reactions at launch were positive about the sound while acknowledging how crowded the TS-style market is. Gearnews summed it up: "Overall, you get the best parts of the classic Tubescreamer tone, with that added flexibility of the new voicing and that extra MOSFET stage," while adding that "whether it will stand out in a crowded market is yet to be seen"3.
That Pedal Show put the Moxie alongside a range of Tube Screamer-style pedals in a December 2022 video, demonstrating it with a Gibson ES-335 in a dedicated segment7. On the show, Dan Steinhardt said:
"I thought the Moxie just felt like you know for what I'm doing he just sat in a really nice spot"8
Mick Taylor, his co-presenter, called it "the Moxie is killing it sounds awesome" and had the Voice and Fat switch set in what he called a really nice spot, running it into a PRS McCarty Soapbar8. Dan named it his favorite of the day among the pedals they tried8.
Sweetwater's Don Carr demoed the pedal in a launch video, introducing it plainly: "the moxie is wampler's take on the classic ts circuit"9.
Where it sits in the Wampler range
The Moxie is one of several compact overdrives in the Wampler lineup, which also includes mini formats like the Wampler Belle Mini Overdrive and Wampler Plexi-Drive Mini, alongside full-size drives such as the Wampler Euphoria and Wampler Pantheon. What marks the Moxie out within that range is its specific circuit lineage: it is the company's TS10-based design, where most of its other overdrives draw on different reference circuits624.
Wampler builds the Moxie in the U.S.A. and backs it with a limited 5-year warranty, using what the maker describes as "high-grade components selected for superior sound and response, premium finish and controls"1. At $149.97 as listed in October 20261, MusicRadar reported a launch price of $149.99 in August 202210.

Questions
Does the Wampler Moxie take a battery?
No. The Moxie has a 9V power jack but no battery connector inside, so it runs only on an external power supply. It accepts 9V to 18V DC, drawing between 11mA at 9V and 16mA at 18V, which makes it easy to run from most pedalboard power supplies.
Is the Wampler Moxie a Tube Screamer clone?
It is based on the Ibanez TS10 Tube Screamer circuit and uses the classic 4558 chip, but Wampler and the press describe it as a twist on the design rather than a straight clone. It adds a Voice switch that reshapes the EQ and a Fat switch that brings in a custom MOSFET clipping stage for extra gain.
Is the Wampler Moxie true bypass?
Yes. Wampler specifies 3PDT true bypass, so when the pedal is switched off the signal passes through without buffering, which suits players who like to keep their chain as transparent as possible.
Where is the Wampler Moxie made?
Wampler states that the Moxie is built in the U.S.A. It comes with the company's limited 5-year warranty and uses high-grade components selected, in Wampler's words, for superior sound and response.
