ZEQD-Pre Tube Preamp 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 modeling setup.   This pedal is a simple, modern tool devised to give you all the organic sonic character and dynamic response of a tube amp in a compact and convenient form factor. There are no menus to dive through. No IR loading. No firmware updates. No 0s, 1s, or any other pesky digital artifacts to get in the way of you and your tone. The ZEQD-Pre is the no-fuss analog solution to all your digital woes. The ZEQD-Pre features a built-in analog cabinet simulation for realistic amp feel during quiet practice sessions to give you the full EF86 tube character without disturbing your housemates. This feature is handily disengaged via the Cab Bypass switch enabling you to send a pure signal to your preferred IR loader or modeling software and 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. The ZEQD-Pre uses the EF86 pentode—the same tube that gives many Dr. Z amplifiers their pristine hi-fi tone and makes them such responsive pedal platforms. What does that mean for you? It means dynamic and nuanced touch sensitivity, hi-fi full frequency clarity, and an EQ that is both predictable and highly responsive. Though designed with guitarists in mind, the ZEQD-Pre’s broad range of EQ voices and tube warmth can enrich the sonic color and harmonic content of just about anything you can think of plugging into it, including, but not limited to, bass, synths, keys, drums, vocals, and microphones. Each ZEQD-Pre is built by one sophisticated droid and many kind-hearted flesh and blood artisans in the tropical metropolis of Akron, Ohio USA.     Activate Foot Switch: This activates or bypasses the ZEQD-Pre     Boost Foot Switch: This defeats the tone controls and delivers a full range boost without altering the frequency response. This switch is only active when the Activate switch is on.     Bass: Adjusts frequencies from 20Hz-400Hz     Middle: Adjusts frequencies from 400Hz-2KHz     Treble: Adjusts Frequencies from 2KHz-20KHz     Level: Output volume control when the tone controls are active     Boost: Output volume control for when the Boost is active and the tone controls are bypassed.     Ground Lift (On Side): Press for ground lift on the XLR output.     Cab Bypass (On Side): Press to remove the analog cabinet simulation on the XLR out.     Headphone Out (On Side): TRS ¼”     Direct Out (On Side): Balanced XLR     Lifetime Warranty     Input Impedance: 10 MΩ     Output Impedance: Variable     Headphone Out Impedance: 39Ω     Direct Out Impedance: 100Ω     Current Draw: 500mA
