Edp | Bell Sound Effect

Crucially, the effect is non-latching . You have to hold the footswitch down to hear the bell. The moment you let go, the circuit resets. This made it a performance tool for dramatic accents, not an always-on effect. The EDP Bell would have remained a footnote in gear history if not for its use on David Bowie’s 1972 album The Rise and Fall of Ziggy Stardust and the Spiders from Mars . Wait—1972?

That is the archetypal EDP Bell sound. It is dramatic, slightly unnerving, and utterly glam. Electro-Harmonix discontinued the EDP Wobble-Trem by 1977. It was large, expensive, and power-hungry (requiring a specific 40V DC adapter). The bell effect, while cool, was a one-trick pony. Most guitarists ignored it. Crucially, the effect is non-latching

But the EDP had a secret weapon. Buried in its circuitry was a momentary "Touch Wah" feature. When you pressed the footswitch, it would trigger a resonant, harmonic-rich sweep that sounded exactly like a church bell struck with a rubber mallet. It wasn’t a bell in the literal sense—there was no fundamental "ding"—but rather a ringing, metallic, decaying thwack that hovered somewhere between a vibraphone and a fire alarm.
