Warm Audio Pedal76

The Warm Audio Pedal76 is an all-analog, transformer-balanced FET compressor pedal, built to put the compression of Warm Audio's rack-mounted WA76 on a pedalboard. Warm Audio says the pedal accurately reproduces one of the fastest and most powerful studio compressors of all time, known for ultra-fast attack and release, and backs it with more than ten years of experience building the WA76 studio unit¹.

The pedal was unveiled in September 2024 as one of two vintage-inspired analog pedals from the company, applying a FET-driven compression circuit to marshal your transients, as MusicRadar put it at launch². Guitar World described it as Warm Audio repackaging its rack-mounted WA76, a recreation of the Universal Audio 1176, into an all-analog pedal³.

A FET compressor with transformer drive

FET compression is the family of circuit design behind the classic studio limiters of the 1960s and 1970s, where a field-effect transistor controls the gain of the audio path and reacts very quickly to transients. Warm Audio already builds this design as a rack unit: the WA76 is a discrete FET compressor that the company says delivers the same performance as vintage "Rev D" FET compressors, and it lists applications such as tight, deep bass for that unit⁴. The Pedal76 carries the same approach into pedal form, with a custom CineMag USA transformer in the signal path¹.

Warm Audio says that transformer adds rich harmonic content, and that in high gain mode it produces a bit of audible overdrive reminiscent of the most prized studio originals¹. Delicious Audio's Paolo De Gregorio put it in similar terms: "Crank the levels to enjoy the gritty saturation and harmonic richness that make FET compression legendary."⁵

Warm Audio also points to the studio units' pedigree, describing the compression tones as favored by celebrated artists such as Led Zeppelin, Pink Floyd, Periphery and Jack White¹.

The controls

On the front panel, the Pedal76 has Attack and Release, Ratio, and Input controls¹. The Input control sets how hard the compressor is pushed, and the Ratio control sets how much compression is applied. MusicRadar notes that at higher settings, ratios of 12:1 or 20:1, the Pedal76 performs as a limiter, while lower ratios work as conventional compression².

The rear panel carries four switches that Delicious Audio says Warm Audio added for enhanced performance⁵:

• FX Bypass: selects buffered or true bypass³
• Input Sensitivity: matches the pedal to the incoming signal level⁵
• Ground Lift: helps with ground loop hum⁵
• Drive: raises the gain into the transformer for more saturation⁵

What reviewers said

In a 2026 compressor pedal buying guide, Guitar.com found the pedal's size worth weighing against its sound: "It is undeniably large and requires serious board space, but it rewards you with authentic analogue warmth and punch that digital emulations struggle to fully replicate."⁶

On the board and in the rig

The Pedal76 is a large-format pedal, and Guitar.com's reviewer noted it requires serious board space⁶. Where it earns that space, beyond the compression itself, is flexibility at the edges of the signal chain: the switchable buffered or true bypass³ lets it sit in a true-bypass board or act as a buffer, the balanced DI out sends a signal to any mixer or live recording rig¹, and the Ground Lift switch addresses hum when the DI and amp outputs are used together⁵. Players comparing it with other dynamics tools will find it sits in the FET compressor corner of our compressor pedals guide.
