"INCREDIBLE Plugins! Elegant, Simple and AMAZING! So far used it on 6 mixes and the Doubler ALWAYS made the cut! Needed this years ago..."
Ron Harris. Producer (Christina Aguilera).

From the mind of legendary audio equipment designer Paul Wolff comes the new Fix Flanger and Fix Doubler. They take the legacy and sound of classic flanging and vocal doubling of the 1960s, but with all the benefits of the digital world.

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.

Classic Flanging Reimagined 

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.
