The Top Tone – A Guide Review of the Most effective Do-it-yourself Guitar Tube Amplifier Sequence

This article is a book overview on a collection of 6 textbooks that is the most detailed and lucid rationalization of guitar tube amp architecture, circuits, tone, factors and development method for DIYers I have at any time discovered. The critique deals with each reserve individually and recommends acquiring them in a certain purchase to increase your expertise in phase with your building encounter.

Kevin O’Connor of London Electricity has developed a collection of publications underneath the major title of “The Ultimate Tone.” These publications are really unique and diligently tailored for the Do-It-Oneself (Diy) guitar tube amp hobbyist and boutique amplifier builder. The publications have a residence-built ‘feel’ as perfectly… all the illustrations are carried out by hand and the books are photocopy-printed on 8.5″x11″ paper and certain with plastic spines and clear plastic covers. There are 6 books in the series now with the most current getting introduced in the late spring of 2008. You may perhaps want to buy the whole collection all at once and get a modest discounts, but I consider you need to take into account getting them 1 at a time and digest as you go, building assignments together the way. A crucial level although… you don’t necessarily want to buy them in numerical get. I endorse the following sequence:

  1. The Best Tone Quantity 3 – Generations of Tone
  2. The Ultimate Tone Quantity 5 – Tone Capture
  3. The Final Tone Volume 2 – Devices Strategy to Phase Seem Nirvana
  4. The Top Tone Volume 4 – State-of-the-art Methods for Present day Guitar Amp Layout
  5. The Final Tone – Modifying and Custom made Setting up Tube Guitar Amps
  6. The Ultimate Tone Quantity 6 – Timeless Tone Created for the Long run These days

The Ultimate Tone Quantity 3 – Generations of Tone

This is the most essential e-book in the collection for the commencing tube amp builder.

Chapters 2 by means of 4 lay down the foundation of very good Diy tube amp construction, filling you in on great electrical connections, grounding technique, direct dress and other wiring tactics, and mechanical layout which include assembly techniques like terminal strips, turret and eyelet boards.

The subsequent chapters just about every decide a particular ‘iconic’ amplifier, every single legendary amplifier remaining a prototypical instance of amplifiers of its course, and they are examined in detail as to the circuit topology, peculiar tonal characteristics that final result and deadly flaws that the products is notorious for. Kevin gives the original schematics and then shows how you can utilize the procedures detailed in the before chapters to boost the overall performance and dependability of the icon without having harming the tone. The schematics are redrawn, layouts are offered and mechanical solutions are labored out to make each and every chapter a entire, self-contained, build-it-you amp job.

This procedure is recurring for numerous variants of the Champ in chapter 5 (this chapter considerably influenced my very own solitary-ended amp task), then in rapid succession: the Bassman, Plexi, 800, Bull Doggy, AC-30, Portaflex, SVT, Bass Grasp, Custom made Unique, Guitar Mate, Herzog and Laney amplifiers are dealt with.

If you can only purchase a single e book for your Diy guitar amp interest I’d heartily endorse this one.

The Ultimate Tone Volume 5 – Tone Capture

Quantity 5 picks up the place Quantity 3 left off, with a task-oriented solution and some advanced Diy tube amp options for guitar and bass.

The e book begins off with a chapter overviewing vacuum tube operation named ‘tube tone,’ adopted up by a chapter on guitar electronics and pickup characteristics.

The next two chapters are smaller jobs: Sigma for results switching and Triple-X for amplifier switching.

Chapters 5 & 6 are on transformers… significant elements but it produced me yawn, sorry.

Starting off with chapter 7, all the stops are pulled out and you are in venture heaven… Important (200W), Soma 84 (EL84 amp), Standard (the London Electricity Regular Preamp from 1995 coupled to a 50W amp employing four electricity tubes), Doppelsonde (mixing power tube styles), AX84 (discussion on the first goal of a really low output energy amp), Kelly (50W from 4 6V6s), and several other jobs of lesser scope.

1 favorite undertaking I did was dependent on Kevin’s transforming of the HotBox tube preamp pedal from Matchless in chapter 16. I crafted this pedal in a actually “real issue-to-position type” (this means terminal strips) in a tube pedal enclosure from Doug Hoffman, substituting a Baxandall tone stack and transforming the preamp values to be far more Dumble-esqe (non-HRM form).

What would you do to match an amplifier to Yngwie Malmsteen’s model? See chapter 18, ‘Swede.’

The Top Tone Volume 2 – Units Technique to Stage Seem Nirvana

Volume 2 is not task oriented. The bulk of the reserve, chapters 2 through 5, deals with electrical power provide tricks and a complete overview of energy amplifiers, including tube, strong-condition and hybrid electrical power amps. Chapter 3, on tube ability amplifiers, has some quite useful data on mods and fixes to Marshall and Fender bias circuits.

I like the 1st and last chapters of Volume 2 the very best. The very first chapter is a quick discussion of audio levels and how you might setup your gear on phase for the most effective viewers/band knowledge. The very last, chapter 6, is called “Pillars of Tone” and in this chapter the key contributors tone at the block-amount of a guitar tube amplifier method layout are reviewed a person by just one and Kevin supplies some really important perception into tone shaping all through the preamp/amplifier.

The Final Tone Volume 4 – State-of-the-art Tactics for Modern Guitar Amp Layout

This is the book you’ll want to purchase if you really feel the need to have to get deeply associated with the power scaling engineering that Kevin has produced. Energy Scaling, coined and trademarked by Kevin, is the way you can get features of power amp distortion (as opposed to preamp distortion) into your tone at bedroom quantity levels. Quantity 4 is not Do it yourself venture oriented but explores the troubles, together with attenuation, energy scaling (both equally down and up), sag, and power management, tackled by contemporary guitar tube amp designers.

That claimed, the 2nd-to-very last chapter in Volume 4 may possibly be important for a broader team of fanatic builders… style philosophy. In this chapter Kevin gives a hierarchical style course of action that could be utilised to make key selections on how you approach your following challenge.

The Top Tone – Modifying and Custom Creating Tube Guitar Amps

There is no quantity amount in the title of this reserve, it was the 1st. Individually, I bought it for completeness. I especially preferred to have the ‘perfect effects loop’ info, though the loop alone is incorporated into a challenge in Volume 5. TUT also has some superb product on reverbs and signal switching approaches that is not defined in the other volumes. The initially fifty percent of TUT introduces/overviews tube amp units, electrical power provides & grounds then focuses on preamp and energy amp modifications to professional amplifiers (e.g. Marshall / Fender)… if you are completely new to tube electronics you may want to purchase this 1st volume at the exact same time as Quantity 3.

The Best Tone Volume 6 – Timeless Tone Designed for the Foreseeable future Now

In quite a few methods, Volume 6 is a continuation and extension of the material in Quantity 4, where by Electrical power Scaling is launched.  In Volume 6 a new ‘direct control’ model of Powerscaling is featured which was introduced in Vol 4 but flushed out with comprehensive circuits and utilized to ‘sag’ and maintain handle as well in Vol 6.  The new scaling circuits have lots of strengths for a DIY builder like higher sound immunity and considerably less sensitivity to format, and so on.

I utilized the new DC Power Scaling to a Trainwreck clone undertaking and was genuinely impressed with the advancement in ‘playability’ at decreased volumes… the unmodified Trainwreck Express circuit is just much too loud for domestic use, needing to be cranked to get the sweet tones it is renowned for.

A single of the chapters in Volume 6 is devoted to the Dumble amplifiers… anything I was actually looking forward to since a lot of of my interest initiatives emphasis on those people circuits.  I discovered this limited chapter to be a great introduction to the in general architecture of the Dumble amps, written from the place of view of the evolution from the early modified regular amps that Alexander Dumble commenced out executing, but I felt the chapter fell small in discussing some of the more vital subtleties of the later Dumble types.

Quantity 6 also has plenty of other substance in it, like a wonderful tutorial on planning actually large output electrical power amplifiers and a good chapter on high obtain amplifier patterns with true-planet circuits referenced and specific.

In Summary…

Kevin’s textbooks have a incredibly empirical strategy. He encourages you to set apart convention in some instances or not be worried to attempt combinations of tubes or even pulling tubes and in all situations evidently describes why it is o.k. and points out any explanations why it wouldn’t be o.k. All the illustrations in the textbooks are quite useful and he unquestionably has the DIYer in thoughts as he is writing.

Kevin’s overall body of operate is certainly encyclopedic in nature, and looking at that, 1 characteristic sorely missing from his books is any type of indexing… this is aggravated by the actuality that Kevin regularly refers to preceding writings alternatively than repeat himself in a new volume, and it is very tricky to place your finger on the reference even with the other e-book in hand. Probably look for motor engineering, like Google’s means to search protected articles, could be place to very good use in this situation and deliver a variety of ‘auto-index’ on the website of all of Kevin’s books without basically supplying away the e-book alone. Or superior still, how about an e-book format of Kevin’s complete assortment of TUT guides… I believe all of the e-e book viewers include hunting abilities… and Kevin’s hand-drawn schematics would in all probability scale sufficiently and be really readable on the e-paper displays these units function.

In the meantime, how do you get Kevin’s publications now? The very best way to get the publications is to straight buy them from London Electricity Press. They now have a purchasing cart on http://www.londonpower.com.
