The Ross R60 Flanger is a vintage guitar pedal, that is usable with any electric instrument that you'd want to use it with.
There’s not a ton of info on these old Flanger units, but with the sounds that it produces, a manual is hardly necessary. Man(ual) sets the base notch frequency for the flanging harmonics, and Man/Auto sets the width of the LFO waves’ sweep controlling the effect. Rate controls how fast or slow those waves run, and Recycle rounds out the parameters by setting the amount of flanging depth and resonance. Sitting down with this red menace for just a little while, and you can figure out how to manipulate these knobs to dial in some impressive, space-exploration-infused flanger and phaser tones with ease. Utilizing the now-rare Reticon SAD1024A bucket brigade chip, as well as four RC4558 chips the R-60 produces a chewy, warm flanger sound, ala Lowell George, Andy Summers, Steely Dan and more. A classic type of sound, the fullness and bold sonic flavors that come out of it will transport your rig back to the late 70’s in an instant.
The Ross R60 Flanger definitely has a 'classic' sort of sound, consisting of a good amount of warmth and fullness to the sound. While perhaps not the cleanest sounding flanger out there, the vibe of the pedal more than makes up for it.
