3PDT-STOMP
Active3PDT Stomp Switch (Guitar Pedal Bypass)
3PDT (Triple Pole Double Throw) stomp switch for true bypass guitar effects.
Common Applications
The button every guitarist presses with their foot to activate effects pedals. 3PDT (nine pins) enables true bypass wiring — when the effect is off, the guitar signal passes straight through without any coloring. Found in thousands of boutique and DIY guitar pedals. Press click on, press click off. The stomp mechanism must survive years of being kicked by boots. True bypass is why guitarists obsess over this specific switch type.
Repair & Maintenance
The most commonly failing part in guitar pedals. When the pedal stops switching or switches intermittently, replace this switch first. Easy to desolder and replace. Upgrade to soft-touch relay bypass to eliminate the mechanical switch entirely.
