Flanger Doubler

The MXR Model 126 Flanger/Doubler is an analog delay processor that utilizes "bucket-brigade" technology to create short signal delays. It features two BBD devices, the Reticon SAD1024 and the Reticon R5101 chip. The flanging effect is generated by using very short delay times, resulting in comb filtering that produces the characteristic "swoosh" sound. The delay time can be modulated manually or automatically with a low-frequency oscillator (LFO). Additionally, the delayed signal can be mixed with itself in a feedback loop, and its polarity can be inverted. The MXR Model 126 was used on the recording of "Back On The Chain Gang" by the Pretenders. The unit is also known for its use by famous players such as Eric Johnson, Zakk Wylde, Eddie Van Halen, and Dimebag Darrell. The Doubler mode involves a slight delay, simulating the technique of recording an instrument exactly to deliver a richer rendition of the original. The MXR Model 126 Flanger/Doubler is highly regarded for its flanging capabilities and is sought after for its unique sound.
