This was Randy’s first electric guitar. It was an old guitar that belonged to his mother Delores, and it was used by students at her music school called “Musonia”. After Randy gained interest in electric guitar, she introduced him to Scott Shelly who worked at the school, and during this time Randy learned the basics of the electric guitar.

"I also played an old Harmony Rocket—Dave Davies used one with the Kinks—with the DeArmond screen pickups. It’s a great, coolsounding 335-style guitar, but totally hollow."

Jon Foreman is seen using a Harmony model H59 Rocket 3 pickup in sunburst. Close up shots of Jon with the guitar are seen at 0:03 and 0:13. It is easily identifiable by 3 its Dearmond gold foil pickups, 6 white knobs ; 3 volume and 3 tone knobs, and its rotary selector switch. Along with at 1:26 the headstock and its long writing.

Mentioned in this February 1992 Guitar Player interview, as archived on this Open Computing Facility fan page.

While old Fender Mustangs are his main paramour ("I'm used to them - that was the first guitar I had"), Steve cultivates a modest collection of rarer birds, naturally coveting mod '60s models. "I like Harmony guitars a lot," he says, "the Harmony Rocket, the Harmony Stratotone. Real low-level guitars. Mark and I seem to have a lot of Hagstroms between us. Also, I'd love to have a Mosrite Ventures-type solidbody and a Gretsch DuoJet solidbody." When grilled about his "dream guitar," Turner unearths a real prize: "I really like the Gretsch Astro-Jet, is pretty cool looking - like an SG pulled and stretched." Steve's amp aesthetic is way groovy too. "I've got a pretty old Fender Super Reverb. It doesn't even have a master volume or anything. And I've got smaller things like an Ampeg Portaflex. You can flip the top up and carry it like a suitcase." Turner is particularly proud of his most recent amp dig-up, called the Excelsior. "I bought it at a store that mainly sells accordions. Some accordion player had it in his basement for 20 years. I have no idea where it was made, but the store that sold it to me sold it to this guy 20 years ago!"

In this YouTube video (https://www.youtube.com/watch?v=mFR__Ic_JIs) he can be seen playing a single pickup 6 string Harmony guitar with a cutaway and vertical writing on the headstock at 1:16 which is almost identical to this guitar (https://guitars.azureedge.net/aza/user/gear/1960-harmony-rocket-hollow-body-e-yello-5h5reVk.jpg) - a 1960 Harmony Rocket Single Pickup. The only notable difference is the vertical letters on the headstock. If you pause the video at 1:16 using 0.25x playback speed you can ready the word "SONNY" on the headstock but there are no "Harmony Sonny Guitars" that can be found on Google so the guitar may have been modified at some point by a previous owner or himself.

In an interview with Cultura Livre, Tim Bernardes mentioned that the Harmony Rocket Guitar was previously used by Rodrigo Amarante with Little Joy. The guitar is featured on the "66" album cover and was played by Bernardes during the "Melhor do que Parece Tour."

"I also own a 94 Strat, a 68 Harmony Rocket which i write on a lot, a nylon/classical which i used to write on a lot, and Alvarez 6-string acoustic, an Alvarez 12-str acoustic, a Kay Old Kraftsman Thin-Twin (Jimmy Reed, Hubert Sumlin, & my dad) and an old Fernandes “elephant” battery-powered built-in speaker guitar."

Adam Schlesinger is seen holding a Harmony Rocket Guitar in an image featured on the Rolling Stone website, confirming his use of this specific instrument.

"I’ve had my Gibson for so long that it’s just the one that I play but I actually collect old Supros and Harmonies and Harmony Rockets and hey! I got a H72 at home a Supro Valco a little lap steel Supro guitar with an amp..."
