The GUP Tech Hot Foazz is a fuzz pedal from GUP Tech, positioned by the maker directly against the widely available Behringer SF300. GUP Tech tells players, "If you want an upgrade to your Behringer SF300, this is it!"1
Controls
The layout follows the original Super Fuzz pattern, with two knobs and a toggle1:
| Control | What it does |
|---|---|
| Balance | Volume control |
| Expander | Fuzz level |
| Tone toggle | Down position gives a scooped sound, up position gives a mid-boost |
The scooped setting is the classic Super Fuzz voicing, with the mids cut away to leave a thick low end and a biting top. The mid-boost position is the practical one for playing in a band, since it puts the guitar's fundamental back into the sound1.
Power and bypass
The Hot Foazz runs on a 9Vdc center negative supply and draws 3mA, a very light load that fits easily on any standard pedalboard power supply or daisy chain1. The pedal uses a true bypass design in a solid metal box, so nothing colors your signal when the effect is off1.
Where it comes from: Super Fuzz and the Behringer SF300
The circuit the Hot Foazz recreates has a long line of descent. The original Univox Super Fuzz was followed by Boss's Hyper Fuzz FZ-2, which JHS Pedals describes as "a replica of the now sought after Hyper Fuzz FZ2" in its history of the design23. Behringer's SUPER FUZZ SF300 is a clone of that Boss FZ-2, itself part of the Univox Super Fuzz lineage; Guitar World's fuzz buying guide notes that "somehow Behringer has managed to keep its clone of the FZ-2 in constant production"3. Behringer describes the SF300 as a "3-Mode Fuzz Distortion Effects Pedal" with "3 different sound modes for classic fuzz, grunge and gain boost"4.
The SF300 has also built a reputation for toughness. In a Guitar World torture test it survived "a hefty drop to gravel and a 30-feet fall from the air, with the Behringer battling through every time"5.
The Hot Foazz sits in GUP Tech's own fuzz range alongside pedals like the Phoque Face Fuzz, the Bee Fuzz and the FOAZZ. For more on the effect type generally, see Fuzz Pedals.

Questions
Is the GUP Tech Hot Foazz true bypass?
Yes. GUP Tech describes the Hot Foazz as a solid metal box with a true bypass design, so the pedal is removed from your signal chain entirely when it is switched off. That matters on a pedalboard where several effects sit in front of the amp, since a buffered or non-true-bypass pedal can affect your clean tone even when it is not engaged.
What power supply does the Hot Foazz need?
The Hot Foazz runs on a 9Vdc center negative supply, the standard for most guitar pedals, and draws 3mA. That low draw means it sits comfortably on a daisy chain or an isolated output of a typical pedalboard power supply without eating into the current budget you need for digital pedals.
What colors does the Hot Foazz come in?
GUP Tech lists the Hot Foazz in two colors, Green and Yellow.
What does the Tone switch do on the Hot Foazz?
The Tone toggle switches between two voicings: in the down position it gives a scooped sound with the mids cut, and in the up position it boosts the mids. The classic Super Fuzz sound is the scooped setting, while the mid-boost position helps a guitar cut through a band mix.
