Product Description

In 2021, music hardware/software experts Universal Audio launched their UAFX line of guitar effects pedals — bringing the same class-leading innovation and ease-of-use of its pro audio products to a tactile, plug-and-play stompbox format. The range has been expanded with the addition of the UAFX Max Preamp & Dual Compressor, which puts the colourful sound of three legendary limiters and an iconic tube preamp right at your feet!

3 Iconic Compressors, All In One Pedal!

From the mind of Universal Audio founder Bill Putnam to your pedalboard, Max gives you the same iconic UA 1176 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!

The Max also offers the revered Teletronix LA-2A optical tube limiter that 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. Last but not least, add the grimy squeeze of the classic Dyna "red" comp for lo-fi compression and funky overdrive — perfect for sleazy slide tones!

Legendary UA 610 Tube Preamp & Compressor Stacking

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. With Max, you can easily layer compressors in any combination too for a dizzying array of sounds and textures, letting you push your tones to the front no matter how much limiting you apply.

Phenomenal piece of kit, will no doubt be used for applications other than my pedal board. Studio quality compression and pre amps in a pedal, amazing.
