Discover the classic sound of the world's most famous compressors.

Built upon award-winning UAFX dual-engine processing and a burning desire for the ultimate in sonic legitimacy, Max Preamp & Dual Compressor puts the colorful sound of three legendary limiters and an iconic tube preamp, right at your feet.

Explore Iconic Compression with the UA 1176

From the mind of UA founder Bill Putnam to your pedalboard, Max gives you the same FET compressor used on decades of legendary studio guitar sounds, whether you're looking to make your funk a little funkier, add soulful sustain, or inject subtle infusions of tone.

Get Warm Tube Compression with the Teletronix LA-2A

This legendary optical tube compressor gives you softer, warmer dynamics control versus the 1176. Plus, you can fine tune your compression with a pedal-exclusive Ratio feature, for limiting beyond the vintage hardware and UAD plug-in versions.

Create Funky, Dirty Tones with the MXR Dyna Comp

Add the grimy squeeze of this (in)famous red box to your sounds for lo-fi compression and funky overdrive — perfect for sleazy slide tones.

Add a Legendary UA 610 Tube Preamp to Your Rig

Get the warm detail and character of UA's iconic tube preamp and EQ, and dial in killer sounds with the perfect amount of harmonics and grit.

Stack Compressors for Tones that Go Beyond the Norm

With Max, you can easily layer compressors in any combination for a dizzying array of sounds  — from dense "fuzz" ala' Jimmy Page on Led Zeppelin IV to super squeezed West Coast 70s slide tones to stacked bass compression that "sounds like a record."

Personalize your Pedal with a Mobile App

With the UAFX Control app, you can tweak EQ settings, serial/parallel operation, and add a sidechain bass filter for fully customized compression and preamp effects.
