Light Beam
The Edwards Light Beam is a true rarity among guitar effects, a vintage optical volume pedal that stands apart from the typical potentiometer-based designs. Developed in the late 1960s by the legendary Don Edwards of Guitar City in Denver, Colorado, this unique pedal was created with the needs of pedal steel players in mind. Rather than relying on a standard volume pot, the Light Beam uses an ingenious optical circuit - a light bulb and photocell working in tandem to provide silky-smooth, noiseless volume control. This innovative approach not only eliminates the scratchy taper issues that can plague potentiometer-based pedals, but also imbues the Light Beam with a distinctly organic, almost analog-like feel under the foot. Certain variants of the Light Beam even incorporated a side tone shift control, allowing players to sculpt their volume while preserving their core tone. These expanded models were particularly prized by studio aces like Pete Townshend, who reportedly incorporated the Light Beam into his rig during the early 1970s. With its limited 1968-1971 production run and specialized pedal steel focus, the Edwards Light Beam has developed a devoted cult following among vintage gear aficionados. For those lucky enough to track one down, it offers a truly unique and musical volume control experience - a true testament to the ingenuity of its Denver-based designer.
