Maestro Fuzz-Tone FZ1

The Maestro Fuzz-Tone FZ-1 is a two-knob fuzz pedal that Gibson launched under its Maestro brand name in 1962, and it is widely credited as the world's first fuzz pedal and the first commercially successful stompbox¹²³. Instead of the saturated, sustaining fuzz most players expect today, it was originally marketed to make your guitar achieve tones similar to those of a brass instrument, with the patent application describing a circuit designed to let stringed instruments simulate trumpets, trombones and tubas¹².

That brass-instrument pitch made it a slow start. MusicRadar calls the FZ-1 "largely a commercial failure" in its early days, and Guitar World reports that after an initial production run of five thousand units, sales almost completely dried up⁴⁵. What turned it around was rock and roll: the pedal became the legendary sound on the Rolling Stones' "(I Can't Get No) Satisfaction," after which Gibson was soon selling FZ-1s in their tens of thousands³⁵.

A two-knob fuzz built to sound like a brass instrument

The FZ-1 is about as simple as a pedal gets: two knobs, labeled Volume and Attack, on a wedge-shaped box²⁶. Volume sets the output level; Attack sets the intensity of the fuzz. The circuit inside the original FZ-1 used three germanium transistors powered by two 1.5-volt batteries¹. Coda Effects identifies the original transistors as germanium 1N270s⁸.

The brass-instrument idea came straight from the design brief. The May 3, 1962 patent application describes the goal as providing "a tone modifying attachment and circuit for electrically produced signals which will permit stringed musical" instruments to imitate other instruments². Gibson even made a demo for the pedal that was released on vinyl in 1962⁴. Vintage Guitar notes that the marketing simply did not connect with guitarists at first, which is why the whole first production run sat with dealers until the Stones record changed the picture².

The pedal's low operating voltage is part of its character. Premier Guitar groups the FZ-1 with "lower voltage vintage fuzzes," noting the original ran on 3 volts from AA batteries, a detail that matters to players chasing that sound today, since most modern pedals expect 9 volts⁷⁹¹⁰.

Who invented it, and where it came from

The Fuzz-Tone was designed by recording engineer Glenn Snoddy and WSM-TV engineer Revis Hobbs, and manufactured by Gibson¹¹. Snoddy and Hobbs filed their patent application on May 3, 1962, and Vintage Guitar quotes the pair saying "together we worked out the details of the Fuzz-Tone"². Guitar.com calls it the first fuzz effect to gain widespread popularity¹¹.

Its influence ran well beyond its own sales. In a MusicRadar interview, Craig Hockenberry traced the family tree: "Obviously, the Tone Bender and Fuzz Face, but there were so many others that followed suit"¹². Guitar World likewise credits the FZ-1 with inspiring the Tone Bender, Fuzz Face and many other fuzz designs of the mid-'60s¹².

Early production and price

Gibson built the first run in Kalamazoo, Michigan. The numbers from the press and from serial research⁸⁵²:

Guitar World's Huw Price reports that after the initial five thousand units, sales almost completely dried up until "Satisfaction" revived demand, at which point Gibson was soon selling FZ-1s in their tens of thousands⁵. An original FZ-1 could still be found cheap decades later: Premier Guitar's Ted Drozdowski recalls picking one up "used for about $20 in the early '90s"¹⁴. Today the vintage unit sells for over $600, which is why a clone market exists, with builders like Mozztronics offering FZ-1-inspired pedals at $145¹³.

The FZ-1A, FZ-1B and later versions

Gibson revised the pedal several times over the following decade and a half¹¹⁵²:

The FZ-1A kept the Volume and Attack controls and largely the same three-germanium-transistor circuitry as the original, but moved to Motorola 2N2614 transistors and a single 1.5-volt battery¹²⁸. The FZ-1B was a bigger departure: legendary synthesizer engineer Robert Moog crafted a circuit using a nine-volt power supply that powered two or four silicon transistors depending on the date of manufacture¹. Vintage Guitar describes the FZ-1B as Lincolnwood-built, 9-volt and two-transistor, with revised graphics².

DIY builders still work on the FZ-1A circuit. On the Guitar FX Layouts blog, Travis verified a build using SFT323 transistors (about 200 hfe with a lot of leakage) and noted that PNP transistors with some leakage work best, with two 1µ capacitors in the signal path where any capacitor type will do¹⁷.
