The ALKENE Nashville Overdrive is an overdrive pedal from Browne Amplification, a maker whose range also includes the Protein Dual Overdrive, the Atom and The Carbon. Browne describes the ALKENE as inspired by the classic "Nashville" overdrives found on the pedalboards of session greats from Tim Pierce to Jerry McPherson1.
At its core, Browne says the pedal "combines musical clipping with gentle, amp-like compression, but with more flexibility and control than ever before"1. Around that core the maker lowered the overall gain range so every part of the sweep is usable, restored key mid frequencies so the tone is not overly scooped, and tightened the low end for clarity and punch12.
What it does
Browne positions the ALKENE as a Nashville-style overdrive with amp-like compression rather than a high-gain distortion. The maker says one of its favorite things about the pedal is "its ability to transform those amps, adding the right low mids and just enough" sag, referring to thin, stiff backline amps3. In other words, the pedal is aimed at players who want an overdrive that fattens and softens an amp's front end the way a pushed tube amp would.
The gain structure is deliberately restrained. Browne says it "carefully lowered the overall gain range to make every part of the sweep usable"1, a point Pedal of the Day repeated in its March 2026 review, noting that the maker "carefully lowered the overall gain range to make every part of the sweep usable"2. The reviewer also found that Browne "restored key mid frequencies so it isn't overly scooped" and "tightened the low end for clarity and punch"2.
The controls
The ALKENE keeps its front panel simple, with three knobs and one switch. Browne's suggested starting recipe: set the Tone to taste, fade in the desired amount of Gain, and try turning the Level up to 2 o'clock1.
| Control | What it does |
|---|---|
| Level | Sets output volume; maker suggests starting around 2 o'clock1 |
| Gain | Fades in the amount of drive1 |
| Tone | Shapes the treble, set to taste1 |
| Clipping switch (external) | Toggles between symmetrical and asymmetrical soft clipping1 |
Clipping switch: symmetrical and asymmetrical
The external clipping switch toggles between traditional symmetrical soft clipping and asymmetrical soft clipping1. Right is the stock symmetrical setting; left selects asymmetrical clipping1.
The difference is in how the diodes clip the waveform. Symmetrical clipping cuts both halves of the wave equally, which is the traditional soft-clipping overdrive sound. Asymmetrical clipping clips one half of the wave differently from the other, and Browne says that here it "allows the Green side to open up and bloom in a new way, delivering more punch, a wider feel, and slightly less compression for a more amp-like response"1. Players comparing symmetrical versus asymmetrical circuits can see the same distinction in the Boss SD-1 vs Ibanez TS9 comparison.
Internal switches: More Clip and Low Cut
Inside the pedal are two more switches, which Pedal of the Day summed up as letting you "expand on the original circuit with two internal switches and one external clipping switch, giving you meaningful" tonal options2.
| Switch | Position | What it does |
|---|---|---|
| More Clip (internal, top) | Right | Engages an alternate set of hard clipping diodes, adding extra bite, aggression, and gain1 |
| More Clip (internal, top) | Left | Stock setting1 |
| Low Cut (internal, bottom) | Left | Low Cut enabled: rolls off low end to better fit the rig1 |
The Low Cut switch is a bass cut. Browne says it "lets you roll off just the right amount of low end to better fit your rig," and that if a setup already has plenty of low end, "this switch tightens things up beautifully without thinning your tone"1.
More Clip mode slightly reduces output volume, so the Level control needs to be pushed higher when it is engaged. Browne recommends pairing More Clip with the asymmetrical clipping setting13.
What reviewers said
Pedal of the Day reviewed the ALKENE in March 2026 and was positive about both the look and the flexibility, calling it "an instant classic, this tan beauty is sure to turn some heads"2. On the pedal's purpose, the reviewer wrote:
Reviewers highlighted the range of tonal options available on the ALKENE Nashville Overdrive, noting that its controls allow a player to shape the effect to suit their setup2.
The same review framed the pedal as a cure for thin, stiff backline amps overall, matching the maker's own claim about adding low mids and sag23.
Where it sits in the Browne range
The ALKENE is one of several overdrives from Browne Amplification. The Protein is a dual overdrive whose green side inspired the standalone Atom, while The Carbon and the Carbon X cover other corners of the drive spectrum, and the Ethane Dual Overdrive is a two-sided collaboration with Lee Anderton. The ALKENE is the maker's Nashville-style entry, distinguished by its lowered gain range and its three clipping and filtering switches132.

Questions
What is a Nashville overdrive?
A Nashville overdrive is the style of overdrive pedal associated with Nashville session players. Browne Amplification says the ALKENE is inspired by the classic Nashville overdrives found on the pedalboards of session greats from Tim Pierce to Jerry McPherson. The ALKENE's take on that sound pairs musical clipping with gentle, amp-like compression, a lowered gain range, restored mid frequencies and a tightened low end.
How much does the Browne ALKENE cost?
Browne Amplification lists the ALKENE Nashville Overdrive from $189.00 USD on its product page, as of October 2026. That is the maker's own list price; check the maker's store for the current price and availability.
Why does the ALKENE get quieter in More Clip mode?
The More Clip switch engages an alternate set of hard clipping diodes, and Browne Amplification says this mode slightly reduces output volume. The maker's advice is to push the Level control higher when More Clip is on, and Browne recommends pairing More Clip with the asymmetrical clipping setting.
Which players inspired the ALKENE's Nashville sound?
Browne Amplification says the ALKENE is inspired by the classic Nashville overdrives found on the pedalboards of session greats from Tim Pierce to Jerry McPherson. Those two session players are the only names the maker attaches to the pedal's lineage.
