The story
The Morley company was started by two brothers, Raymond (died June 18, 2002, Los Angeles) and Marvin Lubow (December 13, 1924 – June 2, 2010, Nine Mile Falls, Spokane County) in Los Angeles in the 1960s. Raymond designed a device that is usually referred to as an "oil can delay": an electro-mechanical unit that used a rotating disc coated with electrostatic fluid inside a small metal can. This echo unit made it possible for musical performers to re-create echo effects in a live performance without using echo chambers or unreliable tape devices. The Lubow brothers went into business as Tel-Ray Electronics, manufacturing their new Adineko echo device for many companies including Fender and Gibson. Raymond also designed another device that simulated the sound of a Leslie rotating speaker cabinet in use by organists and other musicians. This device also used the rotating-disc/oil-can method. The Lubow brothers jokingly referred to this new invention as a "Morley" ("More-Lee" as opposed to "Less-Lee").
Shortly thereafter, Tel-Ray shifted their emphasis away from OEM manufacturing and began marketing their own line of pedals under the Morley name. A new treadle and case design consisting of a rather large and industrial-looking chrome-plated housing and rubber-covered treadle was used universally throughout the entire Morley line, which included volume pedals, wah pedals, a rotating sound pedal (the original "Morley"), and a pedal version of their echo device dubbed the Morley EVO-1.
The large chrome plated housing was used through the 1970s as the Morley line grew to include all kinds of effects, including distortion units, flangers, phasers, and some unique devices such as the PKW "Pik-A-Wah" pedal. Morley produced many multi-function pedals such as the PFV "Phaser Volume", the ECV "Echo Chorus Vibrato", the WVO "Wah Volume", the CFL "Chorus Flanger", and the PWF "Power Wah Fuzz".
Morley pedals became known for their rugged construction and overall design. Morley pedals from the 1970s were also AC powered using a standard AC type power cord. Even in the modern day, Morley pedals manufactured during the Tel-Ray/Lubow Brothers period are highly looked at by collectors. When, in the early sixties, Cliff Richard's backing band "The Shadows" became instrumental hit-makers, their then-innovative sound was partly owing to lead guitar player Hank Marvin’s Morley echo unit.
In the 1980s Morley reduced the housing and treadle size of their pedals significantly and eventually changed the chassis to black. 9VDC battery power with an AC adapter jack (wall-wart jack) became standard as Morley pedals evolved in an effort to compete with the new compact pedals from companies like Boss, Ibanez, and DOD. Morley also manufactured some small non-treadle style effects for a while.
Morley was sold to a Chicago based firm, Sound Enhancements, Inc., in 1989. The modern Morley company continues to use the electro-optical circuitry and basic pedal layout pioneered by Raymond and Marvin Lubow in the 1960s, albeit with some refinements. Original Morley pedals were strictly AC powered, whereas the current models are powered by a 9V battery with AC adapter capability. Tel-Ray Morleys used a small light-bulb to illuminate the photoresistor; modern Morleys use LEDs.
Although there is no direct connection between the new Morley company and the now defunct Tel-Ray company, Morley graciously continues to provide documentation for the old product line (Owner's Manuals and schematics) through their website. Light bulbs and some parts for the old Tel-Ray pedals are still available through Morley.
