“Sound Advice from Gerald Weber” Everything you wanted to ask about Vacuum Tube Guitar Amplifiers. Foreword by Aspen Pittman. As an advice columnist for over 20 years in three major guitar magazines, Gerald Weber has probably answered more tube amp questions than anyone. In Gerald’s 5th book about Vacuum Tube Amplifiers, he answers over 300 useful questions…

Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn't change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the "iconic" amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product.

Guitar Amplifier Overdrive: A Visual Tour is an analysis of how tube guitar amplifiers produce their overdrive tones. A visual tour of common tube circuit behaviors. Explanations and illustrations of nonlinear and time-varying circuit behaviors and their impacts on tone. Dr. Ulrich Neumann is a professor of Computer Science, with a joint appointment in Electrical Engineering, at the University of Southern California in Los Angeles. He completed a Bachelors and Masters degree in Electrical Engineering from the State University of New York at Buffalo and was granted a computer science Ph.D at the University of North Carolina at Chapel hill. His academic research relates to Computer Graphics and Computer Vision. He received an NSF CAREER award. He was an Associate Editor for the IEEE Transactions on Multimedia.

Every part of your system contributes to your Ultimate Tone, so every part is important. The Ultimate Tone, Volume 5 delineates, in clear language, the function of each electronic component in a circuit, and how alterations to the value of each part affect the final sound. Gain stage voicing, interstage attenuator optimization, sustain restoration for clean and distorted tones, power amp and preamp "tone generators", simple boost pedals, amp selectors and power conditioners are all covered, with designs using off-the-shelf parts. Like TUT3, this is a "project book" presenting design challenges and solutions, with a diversity of tube and solid-state circuits for bass, guitar and keyboards.

This book offers a simplified method for designing tube power amps for audio. Tube operation is explained, as are circuit principles. Class-A or B, cathode, fixed bias, and push-pull and single-ended designs are covered, as are many front-end circuits. Includes designs using off-the-shelf transformers and current production tubes. Power outputs of 15 to 400W are depicted using pentodes and true triodes. Also, covers power supplies, selected tube data, and information on Hammond and Plitron transformers. Guitar amp builders please refer to "The Ultimate Tone Vol. 2"

The achievement of great, live sound is the premise used to explore modern high-gain guitar pre-amps, proper treatment of acoustic instruments, tube vocal PAs; dynamic bass gear, all types of tube, semi, hybrid and alternative power amplifier design, power supply mods that are "toneful", simple switching methods, speaker cabinet design, getting the most from effects loops and chains, and, modular stage monitoring systems that work!

The evolution of guitar amp circuits becomes a revolution! The Ultimate Tone, Volume 6 takes you through advanced DC Power Scaling methods; reveals the secrets of Dumble amps; explores the truth about high-gain preamps; demonstrates how to build Z-B-X push-pull power amps with a single power tube; simplifies the design of 400W+ tube amps - methods that can be applied to any power level; presents class-G tube amps where 100W of output has the same waste heat as a 25W amp; explores modern mains control and sustain circuitry.

Outlines, in schematic form, many approaches that achieve the goal of power scaling, super scaling and power management. A complete history and discourse on the technology outlines how to implement multiple power scale controls, alternative circuit forms and system impacts. Further tutorials outline the methods for super scaling, with both fixed and variable boost ratios, using both solid-state and tube methods.
