Universal Audio Max Preamp & Dual Compressor UA-FX Effects Pedal

The UAFX Max Preamp & Dual Compressor is a premium dual-engine stompbox from Universal Audio that combines a high-fidelity tube-preamp emulation with two fully independent compressor sections — designed to bring studio-level dynamics and tone to your pedalboard.
At its core: you get the character of the legendary UA 610 tube preamp/EQ section, plus the sonic shape and attack of three classic compressor styles — all configurable in stereo and stackable in various ways.

Key Features & Tone Highlights

• Three compressor models in one pedal: Includes emulations of the FET-style UA 1176, the optical tube Teletronix LA-2A, and the classic “Dyna Comp” style stomp.
• Dual compressor sections: Two completely independent compressor channels (Comp 1 and Comp 2), each with its own preamp/EQ and compressor selection, allowing for stacking, parallel operation or separate use.
• Emulated tube preamp/EQ (610-style): A dedicated “Preamp” knob injects the rich harmonic warmth of the UA 610 preamp circuit, plus EQ shelving/controls via the companion app.
• Advanced routing and control via app: With the UAFX Control mobile/desktop app you can customise routing (serial/parallel/split), set side-chain filters (especially useful for the FET mode), tweak low/high shelf EQs and more.
• Stereo I/O, silent switching, and pedalboard-ready format: Ideal for stereo rigs, studio setups or live pedalboards. The buffered bypass ensures signal integrity.

Why It Matters

Compression and preamp coloration are foundational to professional guitar and studio tones — yet many pedals offer only a single mode or limited flexibility. The Max steps up by providing studio-grade features in a stomp format: the kind of compressor colours you’d expect in a high-end recording rack, plus preamp saturation and harmonics, now ready for live or studio rig use.
According to reviewers:

“Two is always better than one … features two identical and stackable sets of classic compressors … along with an emulation of UA’s 610 tube preamp/EQ.”
Additionally:
“For some a good compression box can be an always-on effect — something that makes everything just sound better.”
So for guitarists looking for that “polish”, sustain, and tonal glue — the Max provides serious depth and flexibility.

Ideal Use Cases

• Guitarists who want both subtle and aggressive compression options — from clean funk “chicken-pickin’” to heavy sustain for leads or even modern high-gain.
• Recording setups / pedalboard rigs where you want studio-quality preamp character and compression, but in compact stomp form.
• Players who stack effects and need flexible routing: you can use one compressor at a time, both in series for heavy squash, or parallel for unique textures.
• Multi-instrument/genre players — this pedal is not just for one style; it supports multiple compressor flavours and preamp coloration, making it useful for clean, crunch, ambient, funk, rock or even bass (with caution).

In short: if you’re serious about dynamics control and tone shaping, the UAFX Max Preamp & Dual Compressor is a high-end tool built for depth, flexibility and studio-level performance in pedal-format. Whether you keep it as an “always-on” compression enhancer or use it for aggressive sustain/stacking, it stands out in its class.
