Description

  • Fix Flanger delivers the sound of classic flanging, with extreme control and flexibility
  • Fix Doubler provides lush chorus and rich textures to your vocals
  • Unprecedented hands-on VSO flange control, with servo motor bounce emulation
  • Three versions included: Fix Flanger and Doubler native plug-in, Fix Flanger and Doubler for Modular, and Fix Flanger and Doubler for Amp Room

In 1979, Paul Wolff formalized a vision which was turned into an exclusive limited edition hardware, that became loved among musicians and sound engineers.

In 2015, the Fix Flanger and Doubler is the reincarnation of this vision - a plug-in package that handles hands-on flanging with unique stereo widening methods, as well as vocal doubling with lush chorus and rich textures.

"Both units are very smooth and creamy. Fix Flanger is the first in-the-box flanger that sounds like real old school flanging with a new school twist. And the Fix Doubler adds a wonderful sonic quality and depth."

A Match Made in Heaven
The combined talents of Paul Wolff and Softube brings you a perfect union of vintage sound with the versatility of classic tape effects, as well as the usability of digital plug-ins, all in one package.

Double the Fun
The Fix Flanger brings you the sound of classic tape flanging combined with extreme control and flexibility. If you want to thicken vocals or bring richness to everything from synths, guitars or other polyphonic instruments, then the Fix Doubler delivers.

Out of the public's eye - until now
Both plug-ins are based on Paul Wolff's original analog hardware units from the late 1970's. These units were completely unique as they never made it into serial production. Nevertheless, they were used as a secret sauce in the New York studio Media Sound, producing artists such as Dionne Warwick, Aerosmith and Stevie Wonder.

Classic flanging re-imagined
The Fix Flanger is versatility personified - this flanger is capable of both classic guitar pedal style flanging with a automatically swept flange as well as direct interaction in the manual mode. A VSO mode features unprecedented hands-on control with emulated servo motor bounce and true cross zero flanging, just like a tape machine. Added features such as tap tempo sweep, unique stereo widening methods and selectable delay polarity makes the Fix Flanger the swiss army knife of flangers.

Doubling made simple
The Fix Doubler delivers texture and extraordinary richness to vocals and polyphonic instruments. The algorithms of the Fix Flanger, combined with a streamlined interface and Paul Wolff's unique Auto Double algorithm, makes it easier than ever to get lush chorus and rich layers to your vocal track. With Auto Double, you can get smooth doubling without flanging at delays as low as 3 ms, which no one has ever been able to do before.

    Awesome value for some awesome tools

    I’ve been looking out for both and of these, as possible alternatives to a classic flanger and doubler with more expensive names and prices. Fantastic to get both together at such excellent value - thank you.
