Universal Audio UAFX Max Preamp & Dual Compressor Stereo Effects Pedal

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 limiter 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 Classic 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 and textures, letting you push your tones to the front no matter how much limiting you apply.

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

Note that Max Preamp & Dual Compressor requires a modern 400 mA isolated power supply (sold separately). Go here for power supply recommendations.
