Here is a 1917 Gibson L1 Vintage Archtop Acoustic, Serial #34018 I consider these early Gibson archtops to be some of the most innovative and finely crafted guitars ever made. They were certainly built to last. This one, for instance, is almost 100 years old and it's in perfect playing condition! The mahogany neck is arrow straight, and the carved Adirondack Red Spruce top and mahogany back are crack free. All the wood used in the guitars of this era are from old growth forests that have long been gone from the face of the earth. They simply do not and CANNOT make them quite like this anymore. When Orville Gibson made his first guitar in the 1890s, he developed something the world had never seen - the archtop guitar. For the first 25 years or so of Gibson's history as a company, the archtop guitar was honed and perfected. It wasn't until the 1920s that Gibson changed the construction of the L-Series to flat tops like the kind Robert Johnson used. This guitar was made while Orville Gibson was actually still alive and president of the company. The guitar is entirely original except the tuners, which are replacements that did not require extra holes. The original tuners are included as well and could easily be repaired. There's just one tiny piece of metal that needs to be be refashioned to bring them back to working order. A machinist could easily fix them. The case is a brand new hardshell case. Tonally, these old L1 Archtops are unlike anything else you will ever play. They have a loudness that defies the body size and a clarity and punchiness that is perfect for the blues and ragtime jazz, but sounds great for folky fingerpicking as well. If you're looking for a guitar tone that will stand out from the crowd of Martin Dreadnought and Orchestra clones on the acoustic market, try this guitar. If you don't absolutely love it, there's something broken inside your soul, and you should probably just quit playing. ... https://www.youtube.com/watch?v=wny32B1-LQQ

In this video, we'll install a Hammond 1650HA push-pull output transformer in the 2006 Gibson Epiphone Blues Custom 30 amplifier we recently serviced. After replacing the power transformer with a Mercury Magnetics, this customer decided to go ahead and make this into the most rock solid amp we could make it by replacing the OT. We'll also dig into the power transformer and see if we can determine where the failure occurred.
