MXR Auto Phaser

The MXR Auto Phaser is a professional phasing unit with low distortion, minimal noise, and a wide range of effects. It features easy operation, low power consumption, and a broad supply range, making it suitable for studio, portable mixing, and PA applications. Unlike flanging, its phase-shift response creates non-harmonic notches in the audio spectrum.

Released in 1975

MXR Auto Flanger

The MXR Auto Flanger is a professional audio delay line designed for true flanging in both portable and custom setups. Its versatile controls ensure ease of use, while its precise time delay creates a musical tonality in percussion, distinguishing it from phasing.

Released in 1975

Eventide Model FL201 Instant Flanger

Flanging may not be a popular effect these days, but back in 1975 when the Eventide Model FL201 Instant Flanger was released, it was. The Eventide Model FL201 Instant Flanger was designed to simulate true tape flanging and offered a much deeper flanging effect than anything previously available, it was widely used on many legendary recordings.

Released in 1976

MXR Model 126 Flanger/Doubler

For more than 30 years now, both engineers and musicians have relied upon the MXR Model 126 Flanger/Doubler as one of best-sounding bucket-brigade* flanging effects ever made. Through its signature flanging, doubling, and delay effects, the MXR Model 126 Flanger/Doubler imprints a very unique sonic signature on guitars, bass, keys, drums, or just about any source needing depth and movement.

Roland RE-501 Chorus Echo

The Roland RE-501 Chorus Echo is the final and most advanced tape delay in Roland’s classic series. Combining tape echo, chorus and spring reverb, it features balanced XLR connections, noise reduction circuitry and delays up to 1.8 seconds. Its improved tape transport and sound-on-sound mode made it a studio favourite, delivering warm, analogue effects with reliable performance.

Released in 1981

AMS DM2-20 Tape Phase Simulator

The AMS DM2-20 tape phase simulator is the result of extensive research into the requirements and needs of the recording industry, for accurate simulation of tape phasing. Unlike other units of this kind, which solely mix the delayed signal with the original, the DM2-20 uses two independent delay lines to allow true ‘over the top‘ tape phase simulation.

Released in 1981

Roland SDD-320 Dimension D Chorus

Roland’s Chorus effect that featured heavily on their JC Series guitar amplifiers was a unique and desirable sound back in the late 1970s and early 1980s. The demand for this new chorus effect was so great, Roland developed the Roland SDD-320 Dimension D to satisfy that market demand, and it is quite possibly the greatest chorus effect processor ever made.
