$375 is your absolute final/total here for the Shift Line Flex pedal, analog tube bass preamp, with power supply included!

The Shift Line A+ Flex pedal is a tube bass preamp aimed at players who prefer the classic East Coast sound. At Shift Line, they've always been particularly fascinated with bass-focused devices. Their product lineup includes the Olympic preamp with its "California sound", so the introduction of the East Coast-style Flex preamp was just a matter of time. Shift Line is extremely happy with their Flex preamp pedal, as the Flex can significantly expand your sound palette.



The A+ Flex pedal is a fully analog preamp based on the 12AX7 tube. Flex allows for soft compression and characterful harmonic saturation, while also giving you control over your instrument's tonal balance and volume. Flex has 3 outputs... (main, balanced, and THRU) allowing you to set up multiple independent signal chains. Additionally, you can use Flex as a drive pedal or tone shaper, due to its bypass switch.



KEY FEATURES:

  • Fully fledged tube preamp with high-voltage power.

  • Fully analog signal path.

  • Wide-range input volume control.

  • Control over saturation character within tube stages.

  • Active EQ section with detents in neutral positions.

  • Harmonic saturation for any broadband signal.

  • Drive/tone shaper pedal capability.

  • Active tube DI Box with high-quality balanced output and Ground Lift function.

  • Small, lightweight, and pedalboard-friendly aluminium enclosure with top-mounted jacks.

The best programming book you will ever read
Format: Paperback
This is without a doubt the best introduction to any programming language you will find. This book takes a hands on approach to learning Python. Concepts are explained clearly and examples and counter-examples are littered throughout each chapters. I like the direct/no waste time with useless preamble approach to explaining key concepts. The explanations are as succinct as it can get. The writer give general advice like not making your solution too generic initially but focus on solving the problem at hand first and then make the code more elaborate. The writer give off a patient tone as he encourages the reader to not be too hard on themselves when they make mistakes but view this as part of the learning process. He gives his own experience and also that of other programmers to encourage the reader to realistically evaluate their circumstances. What I like most about this book is that the exercises are intersperced between the sections within the chapters. That way you get to practice just after learning a new concept. There are final exercises incorporating what was covered in the chapter, the they do not seem to be a summary of all the content. I am reviewing now 23/02/2025. I have read the first 9 chapters and i am currently on chapter 10. When I am done i will update this review. I use Jupter Notebooks to complete exercises. I head the first cell with the problem number and title and set it as a mark-down cell so it heads that mini section and the code window below contains my solution. That way I have all exercises for a chapter in one file and can easily scroll up to see previous solutions and copy code which the problems requests at times. In the end I envisage I will have 20 files - one per chapter.

Great book!
Format: Paperback
Great book! I really like how the instructions are explained in the book and how it encourages you to both use the terminal / python interpreter and make files in vscode. This book can be used for intermediate python programmers and brand new programs. for the intermediate people, its a good refresher of the basics, and by the end you will definitely KNOW, KNOW them. I got this book in prep for new grad job applications, code assessments, game jams, and general practice. So I think you would do good to get this book at any level if you really want to get the basics down and know them!

One of the best Python books
Format: Paperback
I bought 5 Python books as I needed to learn the language quickly for an upcoming project. Of all the books that I purchased, I found this one to be the best. It starts out with the basics and works its way through more complicated areas. Each chapter builds well upon the other. There is very little redundancy, and I was able to get through the book in about a week. I have a background in software development, so this book was able to show me how Python implements different concepts that I already knew, but I think a beginner would also be comfortable with the material.
