The Way Huge Smalls STO Overdrive is a compact, analog overdrive pedal from Way Huge, model number WM25. Way Huge describes it as "delivering smooth, pillowy overdrive straight out of Nashville honky tonks," and the manual calls it a "smooth, silky overdrive that sounds like the purr of a freshly tuned-up muscle car"12. It is a three-knob pedal aimed at players who want a simple, responsive drive rather than a multi-band shaping tool.

The pedal is no longer made. Jim Dunlop lists it as a legacy product, no longer in production, and notes it was produced as a special batch run1. When Gearnews covered it in July 2021, it carried a recommended retail price of USD 1493.

What it does to your sound

The STO is built to add drive gradually while leaving the core tone of your guitar and amp intact. Way Huge says it has "the ability to gradually butter up your tone while preserving the fundamental character of your guitar and amp"1. The company pitches the three-knob layout as "just about the fastest and easiest ride to overdriven paradise"1.

The Drive control gets particular attention from the maker. Way Huge says its "range is wide and responsive and makes it sound like your amp is breaking up naturally without excess volume"1. That points at the pedal's purpose: amp-like breakup at manageable volume, the territory of the Nobels ODR-1 circuit it descends from.

How it is controlled and powered

Power comes from a single 9-volt battery or a 9V DC external supply drawing 10 mA2. The power input is a 5.5mm x 2.1mm jack with the positive voltage on the outer sleeve2, which RockBoard lists as center negative4. At 10 mA it is a light load on any isolated supply.

Plugging in an external power supply disconnects the battery2. The jack expects positive voltage on the outer sleeve, so check your power supply's polarity before connecting it.

The bypass is true hardware switching on a 3PDT footswitch2, so your clean signal passes through untouched when the pedal is off. The manual also lists a noise floor below -100 dBV, A-weighted, with all controls at their mid positions2.

Where the circuit came from

The STO's story starts with a circuit that Way Huge says "has been a special secret passed around for years among Nashville honky tonks and recording studios"1. Gearnews identified that circuit directly: the pedal is "a simple three-knob drive pedal based on the Nobels ODR-1"3. The ODR-1, made by Nobels, is a long-running overdrive with a strong Nashville and session-player following5.

Jeorge Tripps, the designer behind Way Huge, is the person who translated that circuit into the STO. The manual puts it in characteristically colorful terms21:

"When Mr. Jeorge Tripps got hold of one, he stuck his head under the hood and tinkered for days on end"2

The result of that tinkering includes a specific component choice: the manual says the pedal is "equipped with his beloved 4741 op-amp for an even smoother, more pillowy sound"2. For players comparing circuits, the 4741 op-amp is part of what separates the STO from a straight ODR-1 clone.

How it differs from other Way Huge overdrives

The STO sits in the Smalls series, Way Huge's compact enclosure line, alongside drives like the Way Huge Smalls Red Llama Overdrive and the Way Huge Smalls Overrated Special. Where those pedals take different circuit routes, the STO is the company's take on the Nashville ODR-1 sound: three knobs, smooth and pillowy rather than aggressive31.

Gearnews noted at launch that "this new version is nice and compact"3, which was the practical selling point over larger Way Huge enclosures like the Way Huge Green Rhino MKIV or the Way Huge Saucy Box.

What the press said

Coverage at launch was brief but consistent with the maker's positioning. Gearnews described it as a super-smooth overdrive based on the Nobels ODR-1, compact, and priced at USD 149 RRP3. The pedal appeared first on Way Huge's Instagram and on Reverb listings before reaching the main Way Huge site3.

Questions

Is the Way Huge Smalls STO discontinued?

Yes. Jim Dunlop lists the Smalls STO Overdrive as a legacy product that is no longer in production. It was made as a special batch run in the compact Smalls enclosure, so finding one now means the secondhand market rather than a new retail unit.

Is the Smalls STO true bypass?

Yes. The manual specifies a true hardware bypass using a 3PDT footswitch, so the pedal passes your clean signal without buffering when it is switched off. That suits players who want the guitar connected straight to the amp when the drive is disengaged.

Can the Smalls STO run on a battery?

Yes. It runs on a single 9-volt battery, and it also accepts a 9V DC external supply through a 5.5mm x 2.1mm jack. Note that plugging in an external supply disconnects the battery, and the jack expects positive voltage on the outer sleeve.

What op-amp is in the Way Huge Smalls STO?

The manual says Jeorge Tripps equipped the circuit with his beloved 4741 op-amp, which he chose for an even smoother, more pillowy sound. The 4741 is a dual op-amp that shapes the pedal's character alongside the drive circuitry.
