Morley was the name used by Tel-Ray Electronics, Inc.
to market its excellent line of guitar effects pedals in the 1970's. Morley was
famous for manufacturing nearly bullet-proof wah-wah pedals, volume pedals, echo
units, and other effects devices for guitar. The tall chrome Morleys of the 70's
were the Cadillac of their day, both in terms of size and prestige. Ruggedly
built with solid engineering, many Tel-Ray Morleys continue to work even to this
day.
The classic Tel-Ray Morley pedal used a treadle design, with a foot operated
rocker pedal resembling the accelerator of a car. The treadle could be moved
back and forth to control a parameter, or parameters as in the case of
multi-function models. Essentially, Morley took the basic wah-wah rocker pedal
format and applied it to other types of effects - volume pedals, echo pedals,
phasers, flangers, and so forth.
However, whereas conventional wah pedals used a potentiometer driven by a rack
and pinion gear setup, Morley broke ground with an entirely new principle.
Morley pedals used electro-optical circuitry rather than a potentiometer to
control the effect. The foot treadle controlled a shutter inside the pedal that
in turn controlled the amount of light reaching a Light Dependent Resistor (LDR).
This was a revolutionary and clever design, using simple yet sophisticated
circuitry that was entirely new to effects pedals at the time. The advantage of
the electro-optical design was that there were no potentiometers in the signal
path to wear out or become "scratchy sounding" over time.
In addition, the LDRs employed in Morley's Volume Pedal design tended to "load"
the guitar less than typical potentiometers, which tended to cut the treble
response of an electric guitar when turned down (very annoying); by contrast,
the sound of an electric guitar retained its high-end when turned down with a
Morley Volume Pedal. Electro-optical circuitry was used throughout the classic
Morley pedal line, which eventually included volume pedals, wah-wah pedals,
delay pedals, chorus and flanger pedals, phasers, and many others. In addition
to their electro-optical circuitry, Morley pedals were AC powered. This allowed
Morleys to handle considerably more dynamic range than other pedals that relied
on a 9-volt battery for power.
