Additionally, I figured having a fair bit of transparency into the process would somehow had credibility to the entire affair. Really, though, I felt like writing this so I did. The end.\u00a0Well, not really. I discovered that I was writing things like &#8220;The Beesly Book&#8221; and figured that I should specify what stuff like that means instead of writing an explanation in each review.<\/p>\n<p>If you&#8217;re at all interested, here&#8217;s what its like for me to write a guitar review.<\/p>\n<p><!--more--><\/p>\n<h2>Books<\/h2>\n<p>When writing about Guild guitars I reference the following three books:<\/p>\n<p><strong><em>The Guild Guitar Book<\/em><\/strong> by Hans Moust<\/p>\n<p><a href=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/GuildGuitarBook.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-11383 size-medium\" src=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/GuildGuitarBook-235x300.jpg\" alt=\"\" width=\"235\" height=\"300\" srcset=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/GuildGuitarBook-235x300.jpg 235w, https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/GuildGuitarBook.jpg 391w\" sizes=\"auto, (max-width: 235px) 100vw, 235px\" \/><\/a>Amazon Link: [\u00a0<a href=\"https:\/\/www.amazon.com\/Guild-Guitar-Book-Hans-Moust\/dp\/0634009664\">here<\/a>\u00a0]\n<p>The Guild Guitar Book is called <em>The Bible<\/em> over on the Let&#8217;s Talk Guild (LTG) forum, and for good reason. Hans Moust probably knows more about the history of Guild and their guitars than anyone on the planet. Hans has access to company records and ledgers that the others authors on this list only dream about.<\/p>\n<p>Hans&#8217; knowledge and attention to detail are legendary and as a result his book is the first one I grab when referencing any Guild guitar. Unfortunately for me, this book only covers Guild guitars up to and including 1977 and most of my reviews are for Guilds from after that period. This book has book great history sections that are well written and easy to read as well as an encyclopedic listing of the guitars from the included timeline. It also has some of the best photos of vintage Guilds that you&#8217;ll ever find.<\/p>\n<p>Hans has helped me repeatedly via email for which I offer my eternal thanks. We all eagerly await the next book that covers the 1980s and beyond, though I&#8217;m sure its release will cause me to have to go back and edit many of my reviews.<\/p>\n<p><strong><em>Guitar Stories Vol 2: The Histories of Cool Guitars (Guitar Stories)<\/em> <\/strong>by Michael Wright<\/p>\n<p><a href=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/HistoryCoolGuitarsVol2.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-11384 size-medium\" src=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/HistoryCoolGuitarsVol2-230x300.jpg\" alt=\"\" width=\"230\" height=\"300\" srcset=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/HistoryCoolGuitarsVol2-230x300.jpg 230w, https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/HistoryCoolGuitarsVol2.jpg 383w\" sizes=\"auto, (max-width: 230px) 100vw, 230px\" \/><\/a>Amazon Link: [\u00a0<a href=\"https:\/\/www.amazon.com\/Guitar-Stories-Vol-Histories-Guitars\/dp\/1884883087\/ref=sr_1_1?s=books&amp;ie=UTF8&amp;qid=1501903015&amp;sr=1-1&amp;keywords=history+cool+guitars\">here<\/a>\u00a0]\n<p>I usually just call this book &#8220;The History of Cool Guitars Vol 2&#8221; or just &#8220;The History of Cool Guitars&#8221; and even those\u00a0shortened titles are too long (and changed <em>Histories<\/em> to <em>History<\/em>).<\/p>\n<p>This book covers a variety of guitar brands that didn&#8217;t make it into volume 1 such as Kay, Veleno, and Guild.

I shoot the guitars on a white background as shown in the pic to the right, though early shots were done on simple foam boards that I bought from Staples.\u00a0My very cramped home office is used as a studio, and I use the term <em>studio<\/em> in the loosest sense of the word.<\/p>\n<p><a href=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/NightbirdPhotoshop-1600.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright size-medium wp-image-11185\" src=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/NightbirdPhotoshop-1600-148x300.jpg\" alt=\"\" width=\"148\" height=\"300\" srcset=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/NightbirdPhotoshop-1600-148x300.jpg 148w, https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/NightbirdPhotoshop-1600.jpg 787w\" sizes=\"auto, (max-width: 148px) 100vw, 148px\" \/><\/a>I currently have a roll of white background paper that I can pull down for photoshoots and depending on the guitar I will also use a softbox or two to get the light the way I like it.<\/p>\n<p>I try not to alter the photos of the guitar except for levels (contrast, brightness, etc.) in order to ensure a white background and proper color rendition of the guitar. Sometimes I will remove a particularly annoying fingerprint that I missed while cleaning the instrument, but I always leave finish issues as they were photographed.<\/p>\n<p>Though I endeavor not to alter the guitar, I do a fair bit of work in Photoshop to make the background pure white, so though I try to give a fair representation of what the guitar looks like (under artificial light, to be fair), even though the photo itself has been altered. The three-tile image of my Guild Nightbird shows an example of this process from when I still used foam boards for backgrounds. Note that I had to remove the gaps between the boards, too. I no longer have to do this with the large paper backdrop.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignright size-medium wp-image-14572\" src=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/2017\/09\/image-225x300.png\" alt=\"\" width=\"225\" height=\"300\" srcset=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/2017\/09\/image-225x300.png 225w, https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/2017\/09\/image.png 600w\" sizes=\"auto, (max-width: 225px) 100vw, 225px\" \/>Update: In early 2019 I invested in a set of ProFoto lights and I now use them for almost all of my shots. This means that between guitars and photography equipment there is now no more room for me in my home office. You may notice that the background is black while the floor is white in this picture, which is how I often shoot guitars where the grain needs to be seen through vibrant colors such as with <a href=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/2017\/07\/GuildNightbirdGGMaple.jpg\">this image<\/a> of an original Guild Nightbird. The lights may be overkill, but they easily allow me to get that washed out background that I favor for my images while pulling all the glorious detail from the subjects.<\/p>\n<h2>Web Images<\/h2>\n<p><a href=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/12\/EMG-AB-Afterbirner-1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright size-medium wp-image-11375\" src=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/12\/EMG-AB-Afterbirner-1-141x300.jpg\" alt=\"\" width=\"141\" height=\"300\" srcset=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/12\/EMG-AB-Afterbirner-1-141x300.jpg 141w, https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/12\/EMG-AB-Afterbirner-1.jpg 239w\" sizes=\"auto, (max-width: 141px) 100vw, 141px\" \/><\/a>I try not to use images from other websites, and when I do I endeavor to give credit appropriately.

When that happens I just use the image and I encourage anyone who claims ownership to contact me for credit.<\/p>\n<p>I do use product images from manufacturer&#8217;s websites from time to time, and the EMG Afterburner shown to the right is such an example. \u00a0I usually only do this when the product is being discussed in a positive light.

Still, I do my best to try and identify what&#8217;s on the guitar.<\/p>\n<h2>Electronics<\/h2>\n<p><a href=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/1988-Guild-Liberator-Elite-HandDrawnWiring.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright size-medium wp-image-10793\" src=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/1988-Guild-Liberator-Elite-HandDrawnWiring-300x232.jpg\" alt=\"\" width=\"300\" height=\"232\" srcset=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/1988-Guild-Liberator-Elite-HandDrawnWiring-300x232.jpg 300w, https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/05\/1988-Guild-Liberator-Elite-HandDrawnWiring.jpg 1600w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a>I have a rule when it comes to guitar-based electronics that became a rule through repeated validation of its need: Never trust the documentation; always measure it yourself.<\/p>\n<p>Every guitar I review starts with me pulling the control panel cover off, taking pictures of what&#8217;s inside, then documenting\u00a0what I find in an ugly pencil-drawn mess like the one shown here. This drawing happens to be from the Guild Liberator Elite that I <a href=\"https:\/\/www.gad.net\/Blog\/2017\/05\/19\/1988-guild-liberator-elite\/\">reviewed<\/a>, and is one of the more complex guitars that I&#8217;ve examined.<\/p>\n<p>In order to get accurate readings I will attempt to read the markings on all pots, resistors (if present) and capacitors. When markings are not present or have been obscured by things like solder, then I measure those components with the proper meter from the list above. \u00a0I work carefully to avoid breaking original solder joints, though I will repair bad solder joints as I find them.<\/p>\n<p><a href=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/04\/Guild-Liberator-Elite-Wiring.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright size-medium wp-image-10298\" src=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/04\/Guild-Liberator-Elite-Wiring-300x238.jpg\" alt=\"\" width=\"300\" height=\"238\" srcset=\"https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/04\/Guild-Liberator-Elite-Wiring-300x238.jpg 300w, https:\/\/www.gad.net\/Blog\/wp-content\/uploads\/3017\/04\/Guild-Liberator-Elite-Wiring.jpg 1026w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a>Once the guitar is documented by hand I take that document and put it into Microsoft Visio which I have used for work for decades.\u00a0I take the hand-drawn information and use Visio to make it into something useful.
