The Mythos Envy Pro Overdrive NV-9 is an overdrive pedal from Mythos Pedals, built around the Tube Screamer-style green overdrive circuit. Where a stock Tube Screamer compresses hard and thins out the low end, the Envy Pro is designed to give you more output, a wider drive range and a thicker low end, with two push switches that address exactly those two habits12.
Mythos describes the design goal in its own words:
"With its increased output, expanded drive range, and thickened low end, the Envy takes the TS formula and makes it more useful for every player, regardless of style."1
A Tube Screamer with more output, drive and low end
On That Pedal Show, Mick identified the two things the Envy Pro is built to fix about Tube Screamers: the heavy compression that comes from the clipping diodes, and the lack of low end, each handled by one of the two push switches flanking the Tone knob3. He called the Envy "one of the few TS types derivatives that I think really holds muster because of those two switches," and found that with the clipping diodes out and the bottom end back in, it becomes a more full-range, versatile overdrive with tons of headroom, sounding to him more like an old 808 than a TS93.
"the Envy is one of the few TS types derivatives that I think really holds muster because of those two switches"3
MusicRadar reported the pedal's arrival in September 2024, noting the same two features: switchable low end and the option to disengage the clipping diodes2.
The controls
The face of the pedal carries three knobs and two push switches2. The knobs follow the classic Tube Screamer layout:
| Control | What it does |
|---|---|
| Drive | Adjusts the amount of overdrive1 |
| Tone | Classic TS-style tone circuit1 |
| Level | Adjusts the output1 |
The Lows and Clip push switches
The two mini push-buttons either side of the Tone knob are what separate the Envy Pro from a stock Tube Screamer3.
| Switch | Up | Pushed down |
|---|---|---|
| Lows | Classic low end | Increased low end1 |
| Clip | Stock TS soft clipping | Diode lift1 |
The Lows switch restores bass that the original circuit cuts. Mick described the up position as "more traditional Tube Screamer territory," with the pushed position adding low end3.
The Clip switch disengages the clipping diodes. In the maker's words, "When the Clip button is pushed the diodes are disengaged for a louder, less compressed, more open sound"1. Mick found that removing the clipping gives "a great deal of more head room"3, and MusicRadar likewise described the button as opening up the sound, making it louder with less compression2.
The socketed op amp
At the core of the Envy Pro is a socketed RC4558P dual op amp chip, so you can pull it and experiment with other dual op amps. The maker lists the RC4558, JRC4558, TL072, OP275, OPA2604 and LM1458N as candidates1. MusicRadar highlighted this as a feature for the DIY modder who wants to fit a preferred op amp2.
Zach of Mythos Pedals has said on many occasions that dual op amps do not sound all that different, but the socket is there for players who want to experiment1.
What reviewers made of it
On That Pedal Show in November 2024, Mick compared the Envy NV-9 Pro alongside an Ibanez TS9, a BK Butler Tube Driver and the Hagerman 12AX7 Overdrive through Two-Rock and PRS amps. His verdict was that with the diodes lifted and the low end restored, the pedal becomes a more full-range, versatile overdrive, and one of the few Tube Screamer derivatives that holds muster3.

Questions
What op amps can I put in the Mythos Envy Pro?
The pedal ships with a socketed RC4558P dual op amp, and the maker lists the RC4558, JRC4558, TL072, OP275, OPA2604 and LM1458N as alternatives you can experiment with. Zach of Mythos has said dual op amps do not sound all that different, but the socket is there if you want to try.
How is the Mythos Envy different from a Tube Screamer?
The circuit is closely related to the Tube Screamer, but the Envy Pro adds more output, an expanded drive range and a thicker low end. Two push switches go further: one restores low end that a stock Tube Screamer cuts, and the other lifts the clipping diodes for a louder, less compressed, more open sound.
Is the Mythos Envy Pro stereo?
No. The Envy Pro Overdrive is mono, with a single input and a single output, as listed on the Mythos Pedals product page.
How big is the Mythos Envy Pro Overdrive?
The enclosure measures 4.82 inches long by 2.62 inches wide by 1.43 inches high, a standard small-form-factor pedalboard footprint, according to the maker's product page.
