Earthquaker Devices ZEQD-Pre

The All-Analog Simulation Solution | A collaboration between EarthQuaker Devices and Dr. Z Amplification

The ZEQD-Pre is an all-analog tube preamplifier that brings together EarthQuaker Devices’ innovative pedal design and Dr. Z Amplification’s decades of tube amp expertise. With a passive three-band EQ, professional headphone output, balanced XLR output, and onboard analog cabinet simulation, the ZEQD-Pre delivers authentic tube warmth and dynamic response in a complete analog amplifier system that fits right on your pedalboard.

Designed to live at the end of your signal chain, the ZEQD-Pre adds classic tube character to everything upstream. Its passive three-band EQ provides precise tonal control - fine-tune your amp’s voice, push its preamp into rich harmonic overdrive, or breathe dimension and life into a modelling setup.

The ZEQD-Pre features a built-in analog cabinet simulation for realistic amp feel during quiet practice sessions, giving you the full EF86 tube character without disturbing your housemates. This feature can be disengaged via the Cab Bypass switch, enabling you to send a pure signal to your preferred IR loader or modelling software, making it perfect for direct recording, backline-free gigs, or hybrid rigs with multiple signal paths.

Hit the Boost footswitch and the three-band EQ drops out completely, delivering a full-range boost with its own dedicated level control. Two distinct tones at your feet - sculpted EQ tone or wide-open boosted voice. Simple, immediate, and musical.
