In the 1970s, Tel-Ray Electronics, founded by the Lubow brothers in Los Angeles, launched its line of pedals under the Morley brand, emphasizing durability and innovation: the aerodynamic chrome pedals, powered by opto-electronic technology, stood out clearly from classic potentiometer-based wah pedals.

The WVO model, also known as the “Wah-Volume,” was born out of this golden age: it combined a wah effect and volume control in an imposing, indestructible case, highly sought after by collectors.

Technical specifications:

• Large air-mounted pedal, fully chrome-plated housing and chassis, typical of Morley pedals from the 1970s.
• AC power supply via integrated wall plug (no 9V power supply or battery).
• Opto-electronic circuit: a photo-resistant cell controlled by a bulb and a movable strip replaces the potentiometers, ensuring crackle-free operation over time.
• Wah filter response extends over more than seven octaves (approximately 25 Hz to 4 kHz), allowing use even with bass or keyboard.
• Built-in switch allows you to switch between volume mode (half-stroke) and wah mode (longer strokes).
• Very sturdy construction, designed to last: most of these pedals are still in use today.

This vintage WVO delivers a more “filtering” wah than the standard Cry Baby wah, with a powerful and clear sweep.

In wah mode, you get an expressive effect, from clean rhythm to sharp high-pitched descents, ideal for funk, psychedelic rock, or expressive solos.

In volume mode, the pedal offers smooth and musical volume control, perfect for subtle crescendos or dynamic passages.

The absence of potentiometers ensures smooth dynamics without crackling, for a consistently clean response, even after decades of use.

This vintage pedal combines retro elegance, technical efficiency, and sonic versatility, making it the perfect choice for musicians looking for an authentic wah-volume with vintage charm: an investment that is as aesthetic as it is musical.
