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.

A 1000-watt speaker cabinet crafted for musicians who demand power and precision. Sunn Amps intends to reinvent the standard 4x12 configuration with the introduction of this new cabinet.
The Sunn Amps DoomBox is built to accommodate both guitar and bass, offering an impressive 1000-watt handling capacity—making it the first commercially available 4x12 cabinet with such high power handling.

Inspired and developed using feedback from artists and bands who rely on the depth of lower tunings and high volume genres, the DoomBox was engineered to meet the unique demands of professional musicians looking for a robust, high-efficiency cab that can translate the raw power of their sound without compromise.
Premium Craftsmanship and Materials
The Doom Box cabinet is crafted from solid finger-jointed Baltic Birch plywood, ensuring both durability and tonal clarity. Each cabinet is constructed by hand in the U.S.A. using original 1930s machinery, the DoomBox reflects Sunn’s historic commitment to quality, contrasting with some of the mass-produced, MDF-based cabinets on the market today. The cabinet’s aluminum basket, ferrite magnet, and custom Sunn weave Tolex with a custom grill design complete its professional-grade build.

Does the guitar’s design encourage sonic exploration more than sight reading?
A popular song between 1910 and 1920 would usually sell millions of copies of sheet music annually. The world population was roughly 25 percent of what it is today, so imagine those sales would be four or five times larger in an alternate-reality 2024. My father is 88, but even with his generation, friends and family would routinely gather around a piano and play and sing their way through a stack of songbooks. (This still happens at my dad’s house every time I’m there.)
Back in their day, recordings of music were a way to promote sheet music. Labels released recordings only after sheet-music sales slowed down on a particular song. That means that until recently, a large section of society not only knew how to read music well, but they did it often—not as often as we stare at our phones, but it was a primary part of home entertainment. By today’s standards, written music feels like a dead language. Music is probably the most common language on Earth, yet I bet it has the highest illiteracy rate.
Developed specifically for Tyler Bryant, the Black Magick Reverb TB is the high-power version of Supro's flagship 1x12 combo amplifier.
At the heart of this all-tube amp is a matched pair of military-grade Sovtek 5881 power tubes configured to deliver 35-Watts of pure Class A power. In addition to the upgraded power section, the Black Magick Reverb TB also features a “bright cap” modification on Channel 1, providing extra sparkle and added versatility when blended with the original Black Magick preamp on Channel 2.
The two complementary channels are summed in parallel and fed into a 2-band EQ followed by tube-driven spring reverb and tremolo effects plus a master volume to tame the output as needed. This unique, signature variant of the Black Magick Reverb is dressed in elegant Black Scandia tolex and comes loaded with a custom-built Supro BD12 speaker made by Celestion.
