If you live in the Baltimore Maryland, Washington DC and Northern Virginia area and you need an experienced and knowledgeable luthier to inspect, repair or help with setting up your guitars action, go to John Warden. You will be happy you did. I have been using his services since the 80s and I will go to no one else. He has checked out and inspected all of my guitar purchases and has tweaked the action on all of mine. I play both acoustic and electric and his expertise and knowledge of them is unsurpassed. I took my stepsons old Gibson Sunburst to him for repair. It had a large crack running from the neck all the way to the bridge. He did an awesome job resurrecting this instrument.

John Warden was the professional I was looking for. He is the Martin Service Center that I was referred to by Martin for service / repair of my D28. It couldn’t have been a better experience. Thank you John!

John saw me on the spur of the moment, because I wasn't happy with the way my Sting P-bass, made in Japan, was sounding with the original pickup. He talked me out of cutting it up for a modern P-bass pickup and suggested I look for a dual rail strat pickup instead. I purchase a cheap one on eBay and installed it. It sounds so much better now. I am happy again. Thanks so much, John, for your suggestion. Mike

First of all Mr. John Warden is a professional, and a master at what he does and his knowledge of the field of guitar repair is refreshing. He is fair, to the point and I respect him. He repaired my Martin Accoustic to new condition and in a timely manner. Thank you John.
