Overview
Redefining the phaser effect from the ground up, Empress Effects has created a phaser pedal unlike anything else on the market. Employing a unique VCA based design, the Empress Phaser Pedal offers unparalleled signal-to-noise ratio. Choose between 2 stage, 4 stage or an Empress exclusive 3 stage mode; all controllable via tap tempo sweeping through an impressive set of 8 waveforms.The Empress Phaser Pedal is the next generation in the evolution of digitally-controlled analog technology. It features an all-analog signal path but is controlled by a microprocessor, allowing it to maintain all its character and analog flavor while adding a ton of possibilities for control and adaptability. Sure, it does the classic jet sounds, super funky auto-wah and ring modulators, as well as having vibrato and Univibe sounds on tap. But what really sets the Empress Phaser Pedal apart are the auto modes: envelope following, audio-triggered sweeps, rhythms and direct control are just a few of the settings found on the Empress Phaser Pedal.
It also offers unsurpassed connectivity by featuring expression pedal control as well as accepting control voltage (CV), external tap, external audio control and MIDI. All of this comes in a rock solid die cast aluminum enclosure with true bypass keeping things clean.
"The Empress Phaser is an incredibly well-designed and high-functioning analog modulation box with multiple stages, waveforms, and enough flexibility to keep you busy in perpetuity."
- Bobby Kittleberger, Guitar Chalk

Features
- Killer Sound Quality - The Signal to Noise ratio is around 104 dB.
- 8 Auto modes - Envelope follower, center & speed, speed(sine), speed(square), audio sweep trigger, random level trigger, rhythms and direct control
- Tap Tempo with Ratios - Use tap tempo to set the phasers speed; the ratio selection makes fast tempos and triplet based phase times easy.
- 2 / 3 / 4 Stages - Select 2, 4 or, an empress exclusive, 3 stages
- 5 Rhythms - Rhythms let your phaser boldly go where no phaser has gone before
- Ultimate Control - Control over width, speed, resonance, waveform, and number of stages.
- 8 Waveforms - Phase through sine, triangle, asymmetric sine, swung sine, sawtooth, reverse sawtooth, square and step waveforms.
- True Bypass - The Empress Phaser Pedal employs true bypass, so you can be sure that it's not affecting the signal when disengaged.
- Gain - Set the output gain of the phaser to match your bypassed signal or use up to 6dB of boost to really drive your preamp
- Small Size - The enclosure measures approximately 4.5" by 3.5" by 1.5", which is delightfully small when considering all the features packed into this unit.
- Unsurpassed Connectivity - The Universal Control Port allows you to connect an expression pedal, external tap switch, control voltage (CV), external audio input and MIDI all using a standard 1/4" jack!
- True Display LEDs - Extremely responsive LEDs always let you know what the phaser is doing and help you adjust the sensitivity in the auto modes.

Understanding AI prompts as a science
Format: Audiobook
Prompt engineering is the art and science of finding the right words to generate the right responses from artificial intelligence (AI). It's becoming a skill in-demand in today's workplaces. It's also becoming an essential skill for life. To understand prompt engineering, you must understand how AI tools understand their inputs. This book explains that to you in many forms.
It covers prompting as it intersects all the major AI disciplines, like general prompts (as in a ChatBot), fine-tuning, and retrieval-augmented generation (RAG). It also introduces how prompting intersects a couple of image-generation tools.
As a scientist, I appreciate the theoretical approach to these practical matters. Too many people are hacks at AI these days, and any technical understanding can rapidly advance an individual's effectiveness. Prompt engineering is often made fun of as a "soft" topic, but as this book demonstrates, it intersects all the major AI areas. Presumably less garbage in means less garbage out. This book shows how you can make that take place.
As typical for O'Reilly materials, this book appeals to people who desire an intermediate-to-advanced understanding of how AI works. It's not for the casual user. Anyone technical involved in professional knowledge generation using AI can benefit from understanding the dynamics "under the hood." It's a good, though perhaps not ground-breaking, textbook for those of us unable to take a class in the subject. Prompt engineering may be a soft topic to many, but books like this ground the field in the science that can make or break a digital or software product.

Comprehensive Guide with Practical Insights
Format: Paperback
This is a solid book for understanding the art and science of working with LLMs and other generative AI models. I always struggled with getting the output I was looking for, and wasn't sure how best to "ask" the models for what I wanted. This book did a great job of laying out the strategies and practical guidance to craft the prompts. There were a lot of tips and tricks, but the overall understanding and framework around prompt engineering has been super useful.

A must read!
Format: Paperback
Hands down, the best book on prompt engineering and implementing LLMs. Really enjoyed Michael and James deep dive. Whether you're technical or not, this book is foundational to a deeper understanding in how to properly explore and implement LLMs.

Helpful for GPT/LangChain framework
Format: Paperback
I applaud the authors for putting forth a comprehensive introduction in a rapidly evolving space. I absorbed a lot, helpful as I was developing a prototype — using open source methods.
And that’s where I was disappointed. The LLM and examples are highly adapted to OpenAI’s GPT-x and the bulky LangChain framework, something not obvious until you dig in to the book. Sure, this may be where newbie demand was when the authors began writing. But as the open source models and OpenAI alternatives gain speed (e.g. Llama 3.1, Groq, etc.) this book may quickly need an updated and expanded version to stay relevant.
