Revolutions in
Pedal Steel Guitar History
The design and workings of the Traditional Pedal Steel Guitar (TPSG) have remained essentially unchanged for 50 years. Players have learned to live with its quirks and limitations. However, there have been musical revolutions in the instrument.
Revolution 1: Pedals are added to a steel guitar to change from one open tuning to another. Who needs a console steel with four necks anymore?
Revolution 2: In 1954, on Web Pierce's Slowly, Bud Isaacs uses a pedal, not to change the tuning, but to change the pitches of two strings as part of the melody. Minds are blown!
Revolution 3: Buddy Emmons splits Bud Isaacs’ one pedal into two, each affecting only one string. It separates the two "voices" and expands the musical potential of the pedal steel. Everyone changes their pedal setup to follow suit. (Buddy would also later add the so-called chromatic strings and several mechanical innovations.)
Revolution 4: Lloyd Green adds the F raise to open up another vista for the PSG. The change is first recorded in 1968, on D-I-V-O-R-C-E by Tammy Wynette. Of course the F change becomes part of the standard E9 tuning.
At each step, some limitations inherent in the mechanical or musical design of the instrument were eliminated and its potential expanded. For example, its early design allowed only one or two raises or lowers per string. The styles of music generally played on the pedal steel and the state of the art of the mechanical design of the instrument led to two particular tunings. Therefore, many TPSGs were, and still are, built with two necks.
Later, as triple changes per string were possible, the Universal evolved, wherein one physical neck of 12 strings merged the E9 and B6 tunings to provide the functionality of both standard tunings (Maurice Anderson and Bill Keith were proponents of the Universal.). Nevertheless, many players continue to play double-neck guitars.
Though the design of modern PSGs has improved some limitations, the instrument’s weight, mechanical complexity, difficulty in modifications and maintenance have remained.
Several years ago, Frank Carter, builder of the innovative Infinity Pedal Steel Guitar said, "Mechanically, the pedal steel guitar has gone as far as it can go."
Revolution 5: the OnePSG. Read about : the "Fly By Wire” design of the OnePSG. It’s clear this is revolutionary in the mechanical/electronic sense, but perhaps more importantly, it is revolutionary for the what the design affords a player: new ways to approach the Pedal Steel Guitar musically.
Number of Necks : Instant Copedent Changes
The current prototypes of the OnePSG have one (physical) neck of 10 strings, five pedals, and five knee levers*. However, the OnePSG effectively has an unlimited number of necks / copedents.
Video: Introduction to the OnePSG Alpha Prototype from October, 2021, showing just a few of the OnePSG’s features: instantly swapping copedents, capo-ing, and editing copedents in seconds (aka “virtual re-rodding”).
Imagine a backline with a pedal steel! Anyone could sit at it and have their own personal copedent in seconds.
* The design of the OnePSG also allows for 12-string versions and future models could add pedals and levers.

Weight
A traditional PSG is usually built of wood and lots of metal which means it can be quite heavy.
Other than the pedals and knee levers themselves, the OnePSG has essentially no moving parts. It has no pullrods or bell cranks. It doesn’t even have changers.
Imagine tossing your light-weight pedal steel into the overhead on a plane. You know, that pedal steel with the hundreds of necks.

No Compensators
On a traditional PSG, “splits” often have compensators because the simple mechanical interaction of two pedals/levers rarely gets to the exact note desired. Compensators are just additional bellcranks, pull rods, etc. These make a PSG yet more complicated, add weight, and mean more work when making adjustments to the instrument.
Compensators are also sometimes used just to “temper” a pitch that doesn’t directly change, but needs to sound more in tune with other changes.
The OnePSG has no need for compensators because none of those changes are mechanical.
Imagine splits on any string that are always in tune.

Copedent and Temperament
Tuning a PSG involves tuning both the open strings and the pedals and knee levers changes. The latter involves adjusting nylon nuts at the changer end. It can be a tricky business, getting and keeping all the changes in tune.
Imagine pedals and knee levers that stay precisely at the pitch intervals you set them to.
Imagine capoing up ... or even down ... any number of frets.
Imagine being able to sweeten every open string and pedal/lever change.
Imagine simply adjusting all your strings and changes, all at once, any number of cents up or down (e.g., to be able to play with other instruments that are slightly sharp or flat).
