The Mythos Big Puft is a fuzz pedal from Mythos Pedals built around the BMP fuzz circuit, the design lineage most players know from the Electro-Harmonix Big Muff. Mythos describes it as a homage to that circuit rather than a straight copy: "While inspired by the iconic BMP circuit, the Puft is sort of an amalgam of our favorite sounds that style pedal has offered," with what the maker calls a unique Mythos twist1.
That twist is a voicing change. Mythos says Zach and the team tweaked the circuit to have a full and more mid-forward voice, "so the days of getting lost in the mix" are behind it, addressing a common complaint about Big Muff style fuzzes, which can drop out of a band mix because of their scooped midrange1.
The controls
The Big Puft keeps the control layout simple, in the manner of the circuit it honors.
| Control | What it does |
|---|---|
| Sustain | Sets the gain. Mythos says it has "a wide array of gain sounds, so you can take the Big Puft to mellow and smooth to searing levels" of fuzz2 |
| Tone | Tuned so that at noon you get a much flatter EQ sound; reducing or increasing it finds the classic fuzz sounds of the style3 |
On output level, That Pedal Show's Mick and Dan, demoing the Big Puft in an episode that also covered the Cornerstone Nucleo Reverb and Dinosaural Hypoid Drive, noted "bags of variance in all the controls. Absolutely tons of output," describing it as having a large amount of output volume compared to some muffs4.
Power, bypass and build
The Big Puft draws less than 10mA according to Mythos, so it sits comfortably on any standard pedalboard power supply1. It uses true bypass switching, so the pedal is out of the signal path when off1. Connections are quality top mount panel jacks, which keep patch cables tidy on a crowded board1. The pedal lives in a custom bent metal enclosure measuring approximately 4.8" L x 3.7" W x 2.6" H1.
Versions
The NY Blem version is sold through the sale collection while stock lasts, so availability is not ongoing2.
Where it sits in the Mythos fuzz range
The Big Puft is one of several fuzzes in the Mythos lineup. The maker has previously offered the Positron Collider, a Ram's Head style fuzz, the AU-79 Fuzz, the 1347 Silicon Fuzz and the Argo Octave Fuzz. The Big Puft is the lineup's take on the BMP style of fuzz specifically1.
Review video
That Pedal Show demoed the Big Puft, treating it as a pedal in the Big Muff lineage: Mythos describes it as "a homage to the incredible BMP fuzz circuit we all know and love"1. The pair highlighted the Sustain control's wide array of gain sounds, which Mythos says can take the pedal "from mellow and smooth to searing levels" of fuzz3.

Questions
Is the Mythos Big Puft a Big Muff clone?
Mythos Pedals describes the Big Puft as a homage to the BMP fuzz circuit, but not a straight copy. The maker calls it an amalgam of the company's favorite sounds that style of pedal has offered, and says Zach and the team tweaked the circuit for a full and more mid-forward voice so players do not get lost in the mix.
Is the Mythos Big Puft true bypass?
Yes. Mythos Pedals lists the Big Puft with true bypass switching on its product page, along with quality top mount panel jacks.
How much current does the Big Puft draw?
Mythos Pedals specifies a current draw of less than 10mA, which is modest by pedal standards and well within what a standard pedalboard power supply output provides.
What does the Tone knob do on the Big Puft?
Mythos says the Tone knob has been tuned so that at noon you get a much flatter EQ sound, and once you reduce or increase it you find the classic fuzz sounds associated with this style of circuit.
What is the NY Blem version of the Big Puft?
The NY Blem is a blemished version of the Big Puft Fuzz Device sold in Mythos Pedals' sale collection as a deal while stock lasts. Functionally it is the same circuit; the marking refers to cosmetic blemishes.
