Introduction and What type of Gibson guitar do I have. Before collectibility and value can be determined about a Gibson guitar and before you email. Gibson guitar do I have. The type of guitar flattop, archtop, solidbody, lapsteel, etc. The exact model within the type. The year it was made or approximate yearera. Oringinality have any of the parts been changed or modified. First Determine the Type of Guitar and the Model. Sometimes there is a tag inside the guitar stating the style or model. If the model is hollow, look on the inside for any tags and made. But unfortunately, especially on the low to mid line models. NO tag or label inside the guitar specifying what it is. If this is the case, start at the beginning and first determine what. These are several different types of Gibson guitars made. Once this is known, go directly to the section about. Here are the general types of Gibson guitars. Electric Solid body Gibsons body is a solid piece of wood. Flattop Acoustic Gibsons single round sound. Acoustic Archtop Gibsons two f hole style. Electric Archtop Gibsons same as above f holes, arch top. Electric Thinline Archtop Gibsons same as above electric. These are always electric from the factory. Electric Lapsteel Gibson a small solidbody guitar no cutouts. Hawaiian style, with a metal slide bar, pickup and knob routed into the top. Once the type of guitar is determined, figuring out the exact model is. MUCH easier just go to one of the above six linked webpages that describes your guitar. Next Determine the Year or Approximate Year. Gibson guitars usually have a FON Factory Order Number, a serial number, or both. Various serial number systems were used by Gibson. See the serial numberFON section for details. Duplicate or no serialFON number doesnt make things easy, but there are other traits that allow the. General Specs section. Also mid to top end instruments usually have a label inside. Guitars with no label are usually lower end instruments. Probably the first thing when trying to determine the year on an old Gibson. WW2, during WW2, or post WW2. This is easy to do, as Gibson. WW2, wartime, and post WW2. General Specs section for more details. Knowing the general era of the Gibson guitar will make Gibsons rather complicated. FON systems less tangled. Next Determine the Exact Model. There are several general questions which can be asked in determining a guitars model. What is the color of the top of the guitar Common top colors. What is the color of the back of the guitarCommon back colors. What is the body size This is really important for all model types except solidbody electrics. What is the style of fingerboard inlays What is the style of Gibson peghead logo That is, is it white silkscreen. Also if the logo is pre WW2, wartime, or post WW2 see above. Also fancier models can even have some sort of pearl inlaid decoration a crown or long. Gibson logo. What is the style of bindingBinding is the whitishyellowishtortoise band that goes. Most Gibsons have some sort of body binding. Often binding is multi layers whiteblackwhite, etc. Some guitars also have binding on the neck. The more binding a guitar has, the fancier. Finally Determine the Originality. Originality of an instrument is very important. Modifications any modifications. This will greatly influence. Modifications can often be determined by looking at the model. Gibson Model Collectibility. Vintage Archtop Gibsons Collectibility. Gibson invented the archtop guitar as we know it and has remained one of. The most collectible Gibson archtops are the larger. The. Advance 1. 7 or wider models from late 1. The Lloyd Loar signed. L 5s, the pre war. Super 4. 00, and Advanced. L 5 archtops are highly. The pre war cutaway L 5 and cutaway Super 4. Premier models. Non cutaway models are not nearly as collectible as. Premier models. Cutaway archtop models made from 1. Advance Premier models. Non cutaway. post war models are interesting but not very collectible. Archtop cutaway models made from 1. Vintage Flattop Gibson Collectibility. Gibson began to develop professional quality flat top instrument in the. Many concepts were stolen from Martin, which was the company. X braced tops and large dreadnought. Gibson then modified Martins designs and. Although workmanship on pre war. Gibsons is not as high as pre war Martins, Gibson flat tops. Many player including me prefer Gibsons of this period to all other. Flat tops of the 1. Since they are much more common, they are also easier and. Gibson flat tops of the 1. This is. generally blamed on adjustable bridges that were standard on all models in. Also the end of sloped shoulder body styles helped alienate. Vintage Electric Arch top Gibson Collectibility. Pre war Gibson electric arch tops are excellent instruments. Since pre war. models are early in the evolution of the electric guitar, they are. The. ES 2. 50, both used by Charlie. Christian, are very collectible pre war instruments. Postwar full depth, non cutaway models were generally designed as student. Post war Gison electric archtops with. The deluxe models, such as the. The. laminated body models, such as the. Vintage Electric Thinline Archtop Gibson Collectibility. There are two styles of Thinline Gibson models. First is the fully hollowbody style. These thinline, fully hollow, models are somewhat collectible. The single cutaway Byrdland. L 5. CES is excellent in quality. The. single cutaway ES 3. T. a plainer version of the Byrdland, having the same problems. Fully hollow thinlines such as the double cutaway ES 3. ES 3. 35. Thinline, semi hollow electrics from 1. The ES 3. 35, which had the lowest. ES 3. 55 group, is considered to be the. The VaritoneStereo system of the ES 3. ES 3. 55 is. less desirable than the simple ES 3.
