The Frantone Sputnik is an analog optical compressor pedal made by Frantone. Frantone describes it as a 5:1 ratio analog optical compressor designed for every player, with soft knee limiting and what the maker calls transparent tone. It is hand-made in the USA, housed in a tough cast aluminum case with a Soviet Red Enamel finish, and uses true bypass switching1.
The pedal is deliberately simple. A single Squeeze control sets the amount of compression, and Frantone's own instruction to the player is blunt: "Just set the Squeeze control for the amount of compression and you're done!"1. A jumbo red satellite performance LED on the face of the pedal shows the compressor at work, so a player can see the gain reduction happening in real time rather than guessing by ear1.
Controls and build
The Sputnik's control surface is minimal by design, with three main control knobs enabling an uncommonly wide range of fuzz tones2.
| Control or feature | What it does |
|---|---|
| Squeeze | Sets the amount of compression1 |
| Footswitch | True bypass switching, taking the circuit out of the signal path when off1 |
| Performance LED | Jumbo red satellite LED that shows the compressor at work1 |
| Power | External power jack1 |
Because the ratio is fixed at 5:1 and the knee is soft, the Squeeze knob is the only decision a player makes, setting the amount of compression. For a beginner, that removes the usual compressor questions of ratio, threshold and attack, and for an experienced player it makes the pedal a set-and-forget tool on a board1.
Frantone also points out that the Sputnik's output level is a feature in itself. The maker describes the output as hot enough to be used as an overdrive, yet clear and smooth, so the pedal can double as a level booster that pushes a tube amp into breakup, in the territory of an overdrive or boost pedal rather than a pure level-neutral compressor1.
The build follows Frantone's house style. The case is tough cast aluminum, finished in Soviet Red Enamel, a finish name that plays on the pedal's satellite-era branding, and the whole unit is hand-made in the USA by Frantone1.
How the Sputnik relates to the Frantone Sandwich
Frantone positions the Sputnik within its own line as the "junior cousin to the Sandwich"1. The Sandwich is Frantone's larger compressor, and the Sputnik carries the same optical compression approach in a smaller, simpler format: one Squeeze control instead of a fuller control set, the same true bypass switching, and the same hand-made American construction. A player choosing between the two is essentially choosing between the Sputnik's single-knob simplicity and the Sandwich's more complete control over the compression.
Not to be confused with the Spaceman Sputnik fuzz
The name Sputnik also appears on an unrelated line of fuzz pedals from Spaceman Effects, a different maker. The Spaceman Sputnik is an all-germanium fuzz featuring vintage Soviet transistors, hand-soldered and handmade in Portland, Oregon, and it has since grown into a series including the Sputnik II and the Sputnik III germanium fuzz23. Despite the shared satellite-themed name, the Spaceman pedals are fuzz circuits, not compressors, and have no connection to Frantone's optical compressor. A player searching for the Sputnik should keep the two makers straight, since reviews and listings for one will not describe the other.
Questions
Is the Frantone Sputnik true bypass?
Yes. Frantone specifies true bypass switching on the Sputnik, so the pedal's circuit is fully out of the signal path when it is disengaged. It sits in a tough cast aluminum case finished in Soviet Red Enamel, and is hand-made in the USA by Frantone.
What does the Squeeze control do on the Sputnik?
The Squeeze control sets the amount of compression. Frantone's own description of the pedal keeps it simple: set Squeeze for the amount of compression you want and you are done. The pedal works on a fixed 5:1 ratio with soft knee limiting, so the single knob covers the whole range of squash.
Is the Frantone Sputnik an optical compressor?
Yes. Frantone describes the Sputnik as a 5:1 ratio analog optical compressor. Optical compressors use a light source and a light-dependent element to control gain reduction, which typically gives a smooth, gradual response. Frantone pairs this with soft knee limiting and what it calls transparent tone.
How is the Sputnik related to the Frantone Sandwich?
Frantone calls the Sputnik the junior cousin to the Sandwich. It carries the same optical compressor approach in a smaller, simpler package, with a single Squeeze control instead of a fuller control set.
Where is the Frantone Sputnik made?
The Sputnik is hand-made in the USA by Frantone. It comes in a tough cast aluminum case with a Soviet Red Enamel finish, and carries true bypass switching and an external power jack.
