Jensen Silverbird 1050
Jensen Silverbird 1270
Following up to the recent introduction of the highly successful Blackbird 40 “Reinforced AlNiCo” 12” and 10” speakers, Jensen developed the Silverbird line, aiming to transfer the unique voicing of the BB40 in a more affordable platform, with a specific attention to the top end response, carefully tailored to make the Silverbird speakers greatly suited to overdrive and high-gain applications.
Both the SB12and the SB10 share a new 1 ½” (38mm) aluminum-wound voice coil with a Kapton former, designed to retain the trademark clarity of the Jensen clean tones, paired with a smooth, progressive contour of the top end response, so critical to achieve a detailed yet controlled tone with lead tones. The medium-sized Ceramic magnets provide the necessary strength to have generous yet tight bass, while the new cone membranes, with a specific treatment on the paper surrounds, deliver a balanced response in the midrange and “presence” zone.
The SB12-70 is of course fatter and fuller sounding, while the SB10-50 has a more focused and present response with the typical immediacy of the best 10” speakers. Versatile enough to deliver an open, airy response in open back cabinets, both models can morph into powerful rock’n roll tone machines in closed back enclosures.
The Silverbird line will be available worldwide in the sprinf of 2024, and the prices will be:
Silverbird 12 - C12/70 SB: MAP $93.95, MSRP $144.50
Silverbird 10 - C10/50 SB: MAP $117.95, MSRP $181.50
This 1964 Vibrolux Reverb arrived in all-original condition, right down to a two-prong power cord and a death cap wired to the ground switch. The author’s well-worn Strat is the perfect companion.
In October 2011, a black-panel Vibrolux Reverb appeared on eBay with a short bid time. It was poorly described with miserable pictures and barely any details or description of condition and origin. Normally I walk away from such auctions, but there was something that caught my eye. First, some red on the speaker labels led me to believe they were perhaps OEM Jensens. And while the amp’s faceplate was unreadable, I thought I saw a long pattern of four words with a very short last word, as in “Fender Electrical Instruments Co.,” and not the more common “Fender Musical Instruments.” What if this was a 1964–65 pre-CBS amp and no one else recognized it? In the automated eBay watch-and-bid sniper tool I used back then, I set up a $2,500 max bid to be placed 10 seconds before the auction ended. When I woke up the next morning, I had bought it for $1,860. I felt both happiness and regret. What had I gotten into?
When the amp arrived in Oslo several weeks later, I was thrilled to see an all-original 1964 Vibrolux Reverb with Jensen C10N speakers—highly desirable among Fender amp players and collectors. I pulled out the chassis and noticed a well-preserved circuit board, with the death cap wired to the ground switch and a non-grounded two-prong power cord. The brown electrolytic Mallory DC and filter caps looked surprisingly nice and were not leaking. The resistors on the power tube sockets also seemed to be in good shape. It even had factory-original RCA tubes.
When I woke up the next morning, I had bought it for $1,860. I felt both happiness and regret. What had I gotten into?
If you see a leak on a 30-year-old electrolytic capacitor, I strongly recommend replacing it. Old electrolytic caps can mean little clean headroom and farty bass, since they can’t hold the required DC voltage when you strike a chord and the massive current starts flowing through the power circuitry to the tube plates. But I decided to not replace any tubes, caps, or resistors before testing the amp. And the grille? Wow! I don’t think I have ever seen such a dark brown—and nice—piece of cloth, with just minor rifts.
I uninstalled the speakers and noticed the cones were marinated with a thick layer of dirt, dust, and smoke particles, probably from a long life in smoky clubs and bars. I screwed them back on the baffle without cleaning them. The wood was still whole and robust, but the Tolex had many scars and cigarette burns, and the faceplate and knobs indicated heavy but not rough usage. Surprisingly, the pots rotated very smoothly. All this indicates that an amp has been played on a regular basis. It looked like a true warrior.
I found a 230/110V step-down transformer and flipped power and standby on for a 15-second interval. Without proper grounding, I was careful to not touch any other electrical equipment in the room, since you don’t know what voltage guitar strings might carry when connected to a non-grounded amp. I expected the regular background noise—scratchy pots and pop and crackle from bad tubes—but the amp was dead quiet! I stroked a heavy E chord and got a loud, mellow, and very dark and midrange-y tone. I flipped the bright switch on and increased the treble to 5, which is normally an extremely bright setting on Fender amps.
The dusty speaker cones on these old and inefficient speakers filter out the sharp treble—a truly desirable feature in vintage amps. They really make your guitar and pedals sound smoother and creamier, and this was the darkest sounding Fender amp I have ever come upon. What makes the Vibrolux Reverb so good is the balance between the attack and responsiveness of the lightly driven 10" speakers, and the compression from the smaller power and output transformers. I think Fender nailed it with the size, weight, and power of this 35-watt, dual-6L6GC creation.
Later, I installed a grounded power cord and disabled the death cap and ground switch. I got a 230V high-quality power transformer from Mercury Magnetics. It’s 10 years later, and the amp has, incredibly, never failed me. I play it at carefully selected gigs with the original speakers, tubes, and caps still in place. Someday I might consider installing a 25k mid switch or pot on the back in the ground switch slot. This is a must-have and easily reversible mod for Fender amps lacking a mid-pot. It makes them break up much sooner, with a crunch outside the clean Fender tone borderline.
An important point of this story is that we can’t typically expect this kind of luck with vintage amps. Some maintenance is usually required and will make an amp more reliable and durable. Be sure the electrolytic caps are in good condition, and always bring spare tubes to gigs and practices, or bring a backup amp.
64 Fender Vibrolux Reverb vs 65 Super Reverb speakers
Hear Jens Mosbergvik compare his ’64 Vibrolux’s Jensen C10NS speakers against the CTS ceramic speakers found in a ’65 Super Reverb.
Even her playing style is at odds with itself. "I prefer fingerpicking. I like playing really crunchy, loud, aggressive stuff in the styling of a classical player. And when it comes time to play big power chords, honestly, I just make my fingers bleed," she says. Those divergent personalities and approaches result in singular musical snapshots rather than a predictable path through each performance, song, and album.
Sprinter, from 2015, was angsty, urgent, and erratic. And 2017's Three Futures stripped back the guitar barrage for an electronic bent, centered around stark beats and cold synths. Last year's self-produced Silver Tongue twisted the previous albums' makeup into an unusual two-step that often made the guitars pretty and the synths wicked. (Don't worry, guitar loyalists. There's still some 6-string fire.) And now Thirstier is a concise blast of catchy, power pop numbers that are heavier and shinier.
Out in support of her new album, Torres' October 14 Nashville show had her headlining the Exit/In. Before soundcheck Scott introduced PG to her Tele companions, explained why she'd rather play with bloody fingers than use a pick, and showed how seven stomps cover all the shades of traditional rock guitar and much more.

Thrashy Tele
When Torres first hit PG's radar back in 2015, she was predominately raging onstage with a new-ish stock Fender Jazzmaster. She's still in the Fender family, but she remembers 2016 as the year she first flirted with the Telecaster, and she hasn't since looked back. Her current main squeeze is this Fender American Vintage '72 Telecaster Thinline.
"I'm in every way obsessed with this guitar," gushes Scott in a recent Big 5 video with PG. Some of the reasons she hasn't strayed too far from this particular T is its comfy neck profile, lightweight body, and rounder, more aggressive pickups than her aforementioned Jazzmaster or the ES-335 that was a collective Christmas gift from her family.
She typically plays on Ernie Ball Power Slinkys (.011 –.048), but this run she opted for Regular Slinky .010s. However, that experiment appears to be fleeting as she mentions in the Rundown that she's been breaking a lot more strings with the lighter gauge. And most of the set is in standard tuning, but there is a rare moment or two she'll go down to drop d.
Custom Backup
This T has a Fender Tele Custom makeup, but it's actually a parts guitar. (The dead giveaway being its naked headstock.) If all goes well with the Thinline, this yellow bird stays caged on the sidelines.
Pedal Platform Minus the Tinnitus
Scott has plugged into Blues Juniors and Twin Reverbs, but she feels the sweet spot for her live sound and volume considerations is the Fender Deluxe Reverb. The reissue is completely stock, including its Jensen C-12K speaker with a ceramic magnet.
Dirty Rotten Scoundrels
"Transparent" is a guitardom buzzword. It's often used in marketing speak for the next-best pedal offering organic, free-range, USDA-approved tone. (Okay, that's a bit of a stretch, but you get the point.) Nothing Scott has selected for her stomp station can be described as subtle or translucent. Even her delays and reverbs accentuate weird, supernatural flavor crystals.
The filth and fury comes in the potent pairing of a Joyo Vintage Overdrive and EarthQuaker Devices Palisades. Next is the Death By Audio Echo Dream 2 that brings in modulation, delay, and boost/fuzz. She claims this is her "most-utilized" pedal. She really likes how the echo and fuzz circuits interact with the Joyo. The EQD Afterneath brings in ambient, deep, spelunking reverbs. Beefing up the Afterneath and filling it out with faux synth vibes is the Electro-Harmonix POG2. Another favorite application for the POG2 is pulling its attack all the way down and dramatically gliding into the notes. The Empress Vintage Modified Superdelay is a complex, time-bending tool that sprinkles in modulation, reverse delay, and compression, plus the grit and saturation heard in the old tape echoes. The last pedal is a Meris Enzo that is equal parts inspiring and frustrating. The multi-voice synthesizer reacts differently to each note played by Torres. "I have a hard time getting it under control and taming the beast, but that's what I love about it."
