A pillar of savage guitar rock sounds finds expression in a slick, silvery stomp.
Jackson Audio 1484 Twin Twelve Pedal
The Silvertone 1484 Twin Twelve amplifier of the mid 1960s produced a uniquely glassy and characterful tone that’s sonic benefits are still being utilized by guitarists like Dan Auerbach, Beck, Dave Grohl, and more. And now, courtesy of Jackson Audio, all of that classic character is available right on your pedalboard! The 1484 Twin Twelve Pedal is a dead-on-accurate re-creation of both the original amp’s tone and style, right down to the crystal red lens cap. The 2-band EQ makes enhancing that hearty low end or mixing in some bell-like treble a cinch, while the gain control unearths the realistic breakup of the Twin Twelve cabinet. Just ask our Sweetwater guitarists who’ve come face to face with the real deal — Jackson Audio nailed it on this one!

This wonky Zim-Gar was one of many guitars sold by importer Gar-Zim Musical Instruments, operated by Larry Zimmerman and his wife.
The 1960s were strange days indeed for import guitars, like this cleaver-friendly Zim-Gar electric.
Recently I started sharing my work office with a true gem of a guy … one of the nicest fellas I’ve ever come across. If you’ve been following my column here, you might remember my other work mate Dylan, who is always telling me about new, fad-type things (like hot Honey guitars) and trying to convince me to use AI more. (What can I say, he’s a millennial.) But Steve, on the other hand, is about 10 years my senior and is a native New Yorker—Brooklyn actually, from the Canarsie neighborhood. Steve is a retired teacher and spent many years teaching in the Brownsville area of Brooklyn, and man, he has some amazing stories.
Mostly we talk about music and sports (he’s exiled here among us Philadelphia sports fans) and he’s just endlessly interesting to me. He has a huge appetite and can eat a whole pizza. When he talks, he sounds like one of the Ramones and he still has an apartment in Rockaway Beach. We both love Seinfeld and, like George Costanza, Steve knows where all the great bathrooms are across New York City. Since he’s been added to my circle (and is such a mensch), I decided I should work him into a column.
So here’s the connection: Back in the day there were many American importers, dealers, and wholesalers. A lot of them were based in New York, Chicago, and Los Angeles, but I only know of one guitar importer located in Brooklyn: Gar-Zim Musical Instruments. The company was run by Larry Zimmerman and his wife, and the couple had some success importing and selling Japanese guitars and drums. I used to see early Teisco imports with the Zim-Gar badge, which was the brand name of Gar-Zim. I’ve also seen Kawai guitars with the Zim-Gar label, but the Zimmerman’s seemed to sell cheaper and cheaper gear as the ’60s wore on, including the piece you see here.
“This build reminds me of the cutting boards I used to make in wood shop back in my high school days.”
The model name and factory origin of this guitar is a mystery to me, but this build reminds me of the cutting boards I used to make in wood shop back in my high school days. The guitar is just flat across the top and back, with absolutely no contouring or shaping. Its offset body is plywood with a thin veneer on the top and back. From a distance this guitar actually looks kind of nice, but up close you can see a rather crude and clunky instrument that offers little flexibility and playability. The non-adjustable bridge is off center, as is the tremolo. It was really hard to get this guitar playing well, but in the end it was worth it, because the pickups were the saving grace. Another example of gold-foils, these units sound strong and raw. The electronics consist of an on/off switch for each pickup and a volume and tone knob. The tuners are okay, and the headstock design is reminiscent of the Kay “dragon snout” shape of the mid to late ’60s, which is where I would place the birthdate of this one, probably circa 1966. Everything is just so goofy about this build—even the upper strap button is located on the back of the neck. It reminds me of that era when simple wood factories that were making furniture were tasked with building electric guitars, and they simply didn’t know what they were doing. So, you get oddities like this one.
Gar-Zim continued to sell guitars and other musical instruments through the 1970s and possibly into the ’80s. I once even saw a guitar with the label Lim-Gar, which is totally puzzling. I think there should’ve been a Stee-Gar designation for my new buddy Steve-o! Yes, good readers, with guitars and me, there are always just a few degrees of separation.

Our columnist’s silver-panel Fender Bandmaster.
How this longstanding, classic tube amp design evolved from its introduction in 1953.
I have a silver-panel Bandmaster Reverb that I don’t think I’ve talked about enough in this column. It’s one of the most versatile and flexible amps I own, so I use it for everything. It’s portable, has tube-driven reverb and tremolo, and has a full set of EQ knobs including the critical bright switch, which we discussed the importance of earlier this year (“How to ‘Trebleshoot’ a Vintage Fender Amp,” March 2025). The amp is not only pedal-friendly; the flexible 4-ohm output impedance will handle almost all speaker configurations and sound any way you’d like. Let’s take a deeper look at the Fender Bandmaster amp and walk through its development through the years.
The first Bandmaster was introduced in 1953 as a wide-panel tweed amp with Fender’s 5C7 circuit. This rare combo was loaded with a single 15" Jensen P15N and powered by dual 6L6GC tubes in push-pull configuration to produce a modest 25 watts. The 6L6GCs were cathode biased and along with the 5U4GB rectifier tube contributed to a forgiving sag, early breakup, and a midrange-y voice.
Fender made several changes when they launched that amp’s successor in 1955, the more widely known 5E7 narrow-panel Bandmaster, a well-proven amp that has come back as a reissue model. It was still a dual-channel amp—instrument and microphone—but the newer 5E7 model had a fixed bias and a negative feedback loop, providing a louder, firmer, and cleaner tone. Most importantly, the single 15" speaker was replaced by three 10" speakers, making it very similar to the narrow-panel tweed Bassman, the granddaddy of all Marshall amps. This Bandmaster had three speakers instead of the Bassman’s four, and it delivered 25–30 watts instead of 40. It offered early breakup with a midrange-y, big and full tone.
For those not acquainted with tweed amps, the volume and EQ knobs behave differently than on silver- and black-panel Fender amps. The volume pot can act like a distortion control, while the EQ knobs control the volume, and many players I’ve talked to have not really unlocked this secret. This works because, in these circuits, the volume pot sits right before the preamp tube, which allows it to push the tube into full distortion. Since the EQ pots are located right after and are capable of reducing the volume, you’re able to distort the preamp at low volume settings.
“Things became more standardized in 1964 with the arrival of the black-panel AB763 Bandmaster, an amp I have worked on a lot and appreciate for its robustness, simplicity, and versatility.”
In 1960, a short-lived and rare Bandmaster dressed in brown tolex and a black faceplate appeared with the 5G7 circuit. From here on, all Bandmasters had the modern top-mounted chassis. With this circuit, the Bandmaster started to both look and sound more like a black-panel amp. It kept the 3x10" speakers but got a diode rectifier and bigger transformers resulting in a 45-watt output. Tremolo was introduced for the first time, and both channels were now intended for guitar.
The following year, a blonde 6G7 Bandmaster followed as a smaller amp head paired with a 1x12 extension cabinet. It had the timeless early blonde looks with cream tolex, brown faceplate, oxblood grill cloth, large Fender logo, and white knobs. But halfway into the blonde era, towards 1964, things turned strange and rather confusing. There were suddenly two 12" speakers, black knobs, a wheat-colored grill cloth, a more slim black-panel-style Fender logo, a black faceplate, and all in various combinations close to the transition into ’64.
Things became more standardized in 1964 with the arrival of the black-panel AB763 Bandmaster, an amp I have worked on a lot and appreciate for its robustness, simplicity, and versatility. It offers a pure, clean, scooped black-panel tone that’s somewhere between a Vibrolux Reverb and Pro Reverb, which share the medium-sized 125A6A output transformer and dual 6L6GC tubes. With its medium/high power and flexible 4-ohm output impedance, it can drive all kinds of speaker cabinets—as long as you stay between 2 and 8 ohms, you are safe.
For a short time in 1967–68, there was a transitional Bandmaster with aluminum trim and black-panel innards before the all-new silver-panel Bandmaster Reverb replaced it in 1968. The small-head cabinet had grown in size and, unfortunately, weight to accommodate the reverb tank. The amp got a 5U4GB rectifier tube along with a few general silver-panel changes to the circuit. Several silver-panel models existed with minor differences until a 70-watt beast version came along in 1977 with master volume.
To my own 1968 Bandmaster Reverb, I have done a few adjustments. First, I made a custom baffle to hold two 8" speakers. I installed a pair of WGS G8C speakers that fit perfectly on the baffle board without colliding with the reverb tank or transformers. Sometimes, I use only one of the 8" speakers for bedroom volume levels. Second, I reversed the bias circuitry to standard AB763 specs, making it easier to adjust bias correctly on both power tubes. If you are into sparkling clean and funky Strat sounds, you would love this little 2x8" combo.
