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 to 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. "¢ Activate footswitch: Activates or bypasses the ZEQD-Pre. "¢ Boost footswitch: 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): Ground lift on the XLR output. "¢ Cab Bypass (On Side): Removes the analog cabinet simulation on the XLR out. "¢ Headphone Out (On Side): TRS jack. "¢ Direct Out (On Side): Balanced XLR. "¢ Mechanical true bypass.Shipping Notes

Unlocking Success Beyond Self-Reliance
Format: Kindle
Dan Sullivan’s book “Who Not How” is a transformative guide that redefines the way we approach challenges and goals. Rather than asking “How can I do this?” the book challenges readers to ask, “Who can help me achieve this?” This shift in thinking opens up the potential for exponential growth, efficiency, and success.
Sullivan’s core premise is that the path to achieving your ambitions isn’t about taking on everything yourself but rather identifying the right people who can help you get there. This insight is particularly valuable for those who find themselves caught in a cycle of overwork and frustration when trying to handle every aspect of their projects or responsibilities alone.
Although, the main idea of the book is inspiring and powerful, the book does come across as promotion of Sullivan’s Strategic Coach program, which might be off-putting for some readers.
While the book is relatively short, it still feels somewhat wordy and could have been more concise. Many chapters follow a predictable pattern: a story about Mr. X who faced a challenge, found a “Who,” achieved success, and then helped the “Who” in return. This repetition can make the narrative feel formulaic at times.
Additionally, there are numerous one-liners throughout the book that seem disconnected from the surrounding text. While these sentences are mostly quotable, their placement can feel abrupt and unrelated to the passage before or after.
Despite these critiques, the book is filled with examples that showcase how leaders and entrepreneurs have leveraged this mindset. By engaging with the right “Who,” you not only save time and energy but also unlock a level of creativity and collaboration that propels your goals further than you could imagine on your own.
For readers seeking to achieve more while doing less, Sullivan’s book is a great read. It offers a liberating perspective that not only boosts productivity but also enhances personal fulfillment by allowing you to focus on what you do best and rely on others for the rest.
I would rate it 4/5 for its mostly thought-provoking content.

The Goto Resource for every Leader
Format: Kindle
The title says it all — Who Not How — and the content brings it to life. At its core, this book reminds us that our greatest calling is rooted in relationships. It’s also where our greatest assets are found. We don’t need to do everything ourselves—we need Whos in our lives, and we need to be a Who in the lives of others. This is a must-have resource for every leader.

An important book to read, and whose concepts MUSTbe put into practice
Format: Kindle
As an admirer of the work that Dan Sullivan and Benjamin Hardy have done individually, I was sure that a collaboration, two “whos” getting together, would be a good hit. And a good it it is!
The issue with these kind of books is what happens immediately after one has finished reading them.
The issue is to put things into practice, and change the way we do things.
This requires thinking, and thinking is hard, and in most cases we do NOT dedicate time to thinking, so the concepts slide into the past, and no change happens.
Time for me, and everyone, to change this default state.
This review is just the start of a written reflection, a “thinking on paper” exercise, like my friend and great thinker Jean Moroney calls it.
For me, it’s time to shift to my journal.
For you, dear readers, it’s time to get this book and read it. Make Dan and Ben your “whos”. Now.
