A Lesson Learned from a ’50s Gretsch

Vintage '50s Gretsch electric guitar

This model, which Gretsch advertised as having both acoustic and electric capabilities, was introduced by the manufacturer in 1955 as an option for acoustic players who were hesitant about going down the electric guitar path.

In the early days of electric guitar production, blunders by those in the industry were not uncommon. Here’s the tale of one unsuccessful model and a young employee’s unfortunate experiment.

Here at Fanny’s House of Music, there’s a lot of virtues we hold dear. We try to be kind to everyone, and treat folks the same regardless of their experience level. But if I had to pick a character trait Fanny’s values most highly, it would be a willingness to learn. Possessing a willingness to learn means infinite potential. It means you can be anything you want to be if you try. It also means humility. Saying, “I don’t know the answer, but I’ll try to find out for you,” tells folks you respect them enough to not make stuff up. There’s a lot of power in admitting you don’t know everything.


If you didn’t know everything in the guitar business in the early to mid 1900s, you were in good company—as so much was only just emerging. In 1936, Charlie Christian ripped open a can of electrical worms when he used his “pick-up unit” to soar over his otherwise acoustic band, establishing the guitar as a solo instrument and touching off a phenomenon in guitar manufacturing. Then, in 1948, Fred Gretsch Jr. returned to the helm at Gretsch—having briefly managed the company in the early ’40s—with a bold new vision that would meet the demands of guitarists wanting to plug in and turn up.

Gretsch began offering exciting custom finishes and all manner of gadgetry and gizmos, but not every guitarist was ready to take the electric plunge. They needed a guitar for the electric skeptic. So, in 1955, the Model 6199 “Convertible” was introduced. “Play it electric or play it acoustic and get top tone either way,” extols the 1955 Gretsch catalog. “That’s because instead of being built-in, the Gretsch Dynasonic pickup of this guitar is suspended clear of the top to allow full, free vibration.”

But, as is so often the case when one tries to be all things to all people, the Convertible was not a big seller. It did, however, attract the attention of prominent jazz guitarist Sal Salvador, pictured proudly with his sunburst Convertible on his album covers. Salvador was a capable performer who valued a willingness to learn, teaching many students privately in New York at the height of his musical popularity.

“If you didn’t know everything in the guitar business in the 1950s, you were in good company.”

In 1956, one of Salvador’s students, 24-year-old Dan Duffy, was hired to oversee quality control at Gretsch. He wrote a book about his experience called Inside the Gretsch Factory 1957/1970. I managed to track down a copy, and found it written in all caps. I delighted myself in imagining Duffy shouting the entire book to someone. It’s really a fun little book. In it, Duffy describes the Convertible as a “good guitar” that had “a great sound but was prone to feedback.”

Duffy had his own learning experience trying to fix this problem. Installing soundposts had a minimal effect, so Duffy decided—in all his 24-year-old wisdom—to stuff it with fiberglass and test it out on a gig. “That night, I shook more than Elvis did,” writes Duffy. “Somehow I got it down my neck and was jumping out of my pants all night.... I brought it to work. I put the air pressure hose inside the guitar and blew it out. The next day, some of the workers complained they had a terrible itch all night. I said, ‘Me, too.’ I knew this was stupid when I was doing it.”

By 1958, when the dust of Duffy’s debacle had settled, the Convertible had become so closely associated with Salvador that Gretsch just went ahead and renamed it the Sal Salvador model. Which brings us to ours: a 1961 Sal Salvador model in great cosmetic condition. It has obviously been well taken care of and is all original. Its remarkable acoustic projection does in fact make it a great choice for someone wanting to switch between plugged and unplugged jazz playing. The inviting C-shape neck feels comfy and the action is 2/32″ on the low side and 1/32″ (!) on the high side. Playing this guitar feels a little like floating on air.

One could easily engage with guitars only on this surface level: assessing the neck angle, the scale length, the condition of the finish, et cetera. But digging a little deeper and indulging our desire to learn guided us on a journey: from the earliest days of amplified instruments to the fine old jazz box laying in my lap today. Here’s hoping these guitars keep passing through our doors and telling us their stories, as long as we are willing to listen.

Hello and welcome back to Mod Garage. Not long ago, I came home late from a band rehearsal, still overly excited about the new songs we played. I got myself a coffee (I know, it's a crazy procedure to calm down) and turned on the TV. I ended up with an old Bonanza episode from the ’60s, the mother of all Western TV series. Hearing the theme after a long time instantly reminded me of the great Al Caiola, who is the prolific session guitarist who plays on the song. With him in mind, I looked up the ’60s Epiphone “Al Caiola” model and decided I want to talk about the Epiphone/Gibson Tone Expressor system that was used in this guitar.

Embracing the idea of an acoustic flattop made with anything other than wood can, understandably, be tricky stuff. There’s a lot of precedent for excellent-sounding acoustics built with alternative materials, though. Carbon-fiber flattops can sound amazing and I’ve been hooked by the sound and playability of Ovation and Adamas instruments many times.
