On Halloween, the pride of New Jersey rock ’n’ roll shook a Montreal arena with a show that lifted the veil between here and the everafter.
It might not seem like it, but Bruce Springsteen is going to die.
I know; it’s a weird thought. The guy is 75 years old, and still puts on three-hour-plus-long shows, without pauses or intermissions. His stamina and spirit put the millennial work-from-home class, whose backs hurt because we “slept weird” or “forgot to use our ergonomic keyboard,” to absolute shame. He leaps and bolts and howls and throws his Telecasters high in the air. No doubt it helps to have access to the best healthcare money can buy, but still, there’s no denying that he’s a specimen of human physical excellence. And yet, Bruce, like the rest of us, will pass from this plane.
Maybe these aren’t the first thoughts you’d expect to have after a rock ’n’ roll show, but rock ’n’ roll is getting old, and one of its most prolific stars has been telling us for the past few years that he’s getting his affairs in order. His current tour, which continues his 2023 world tour celebrated in the recent documentary Road Diary: Bruce Springsteen and the E Street Band, follows his latest LP of original music, 2020’s Letter To You. That record was explicitly and thematically an exploration of the Boss’ mortality, and this year’s jubilant roadshow continues that chapter with shows across the U.S. and Canada.
“The older you get, the more you realize that, unless you’re über-wealthy, you probably have a lot in common with the characters in Springsteen songs.”
I was at the Montreal show on Halloween night, where Bruce, the E Street Band—Steven Van Zandt, Nils Lofgren, Garry Tallent, Max Weinberg, and Roy Bittan, along with Soozie Tyrell, Charles Giordano, and Jake Clemons—and a brilliant backing ensemble of singers and musicians performed for roughly three hours straight. The show rewired my brain. For days after, I was in a feverish state, hatching delusional schemes to get to his other Canadian shows, unconsciously singing the melody of “Dancing in the Dark” on a loop until my partner asked me to stop, listening to every Springsteen album front to back.

I had seen Bruce and the E Street Band in 2012, but something about this time was different, more urgent and powerful. Maybe it’s that the older you get, the more you realize that, unless you’re über-wealthy, you probably have a lot in common with the characters in Springsteen songs. When you’re young, they’re just great songs with abstract stories. Maybe some time around your late 20s, you realize that you aren’t one of the lucky ones anointed to escape the pressures of wage work and monthly rent, and suddenly the plight of the narrator of “Racing in the Street” isn’t so alien. The song’s wistful organ melody takes on a different weight, and the now-signature extended coda that the band played in Montreal, led by that organ, Bittan’s piano, and Weinberg’s tense snare rim snaps, washed across the arena over and again, like years slipping away.
The stakes implicit in most of these stories are that our time is always running out. The decades that we spend just keeping our heads above water foreclose a lot of possibility, the kind promised in the brash harmonica whine and piano strokes that open “Thunder Road” like an outstretched hand, or in the wild, determined sprint of “Born to Run.” If we could live forever, there’d be no urgency to our toils. But we don’t.
Springsteen has long has the ability to turn a sold-out arena into a space as intimate as a small rock club.

Bruce has never shied away from these realities. Take “Atlantic City,” with its unambiguous chorus: “Everything dies, baby, that’s a fact.” (Then, of course, an inkling of hope: “Maybe everything that dies someday comes back.”) Springsteen used those phrases on Nebraska to tell the story of a working person twisted and cornered into despair and desperation, but on All Hallows Eve, as the band rocked through their electrified arrangement of the track, it was hard not to hear them outside of their context, too, as some of the plainest yet most potent words in rock ’n’ roll.
In Montreal, like on the rest of this tour, Bruce guided us through a lifecycle of music and emotion, framed around signposts that underlined our impermanence. In “Letter to You,” he gestured forcefully, his face tight and rippled with passion, an old man recapping the past 50 years of his creative life and his relationship to listeners in one song. “Nightshift,” the well-placed Commodores tune featured on his 2022 covers record, and “Last Man Standing,” were opportunities to mourn Clarence Clemons and Danny Federici, his E Street comrades who went before him, but also his bandmates in his first group, the Castiles. It all came to a head in the night’s elegiac closer, “I’ll See You in My Dreams,” performed solo by Bruce with his acoustic guitar: “Go, and I’ll see you in my dreams,” he calls
I’m still trying to put my finger on exactly why the show felt so important. I’ve circled around it here, but I’m sure I haven’t quite hit on the heart of the matter. Perhaps it’s that, as we’re battered by worsening crises and cornered by impossible costs of living, songs about people trying desperately to feel alive and get free sound especially loud and helpful. Or it could be that having one of our favorite artists acknowledge his mortality, and ours, is like having a weight lifted: Now that it’s out in the open, we can live properly and honestly.
None of us know for sure what’s up around the bend, just out of sight. It could be something amazing; it could be nothing at all. Whatever it is, we’re in it together, and we’ll all get there in our time. Until then, no matter how bad things get, we’ll always have rock ’n’ roll.
Excellent optical and harmonic tremolo circuits—and the ability to blend them to wild, woozy effect—distinguish this modulation collaboration.
On the right, the Harmonic Trem (RED) delivers lush, swirling modulations, while the Optical Trem (BLUE) on the left provides smooth, traditional waves. Use them independently or combine them (MAGENTA) to create a layered, percussive sound that opens up new dimensions in your music. Both tremolos feature independent Speed, Depth, and Volume controls, giving you freedom to dial in each effect to your taste. Fully analog and crafted with precision, the Twin Trem blends history and innovation.

Here are a few tips to get you started on your way to becoming an old-school Fender amp tech.
Back in 1995, when my journey with vintage Fender amps started, I knew little about tube amps. Over 30 years, I’ve gradually learned the hard way how to acquire, play, service, and give advice. If tube amps are to become a hobby for you, I recommend learning some basic maintenance. You’ll be better off in terms of time and money, and even more important, the knowledge about how circuits and components affect tone will give you a wider array of sounds to play with. But where should you start?
Here’s my list of relevant topics that you should be able to master with a little patience and curiosity. My goal is to get you started on your journey to becoming a Fender amp handyman. The topics are sorted by gravity, and you’ll need in-depth studies from reliable sources on each topic. On my website, fenderguru.com, I’ve tried to explain things easily for musicians, but there are many other good Fender amp resources out there.
Safety. First and foremost: There are lethal voltages inside tube amps, much higher than in transistor amps—even after powering some of them off. Learn how to discharge DC voltages before opening an amp. In my website’s buyer’s guide to vintage Fender amps, I have laid out a procedure on how to safely power off and power up these amps by inserting tubes in a specific order.
Speakers. I strongly recommend learning impedance and wiring methods and experimenting with various internal speakers and cabinets. The mathematical formula 1/Rt = 1/R1 + 1/R2 calculates the total impedance for two speakers coupled in parallel; Rt is the total impedance, and R1 and R2 are the impedances of the two speakers. Remember that all Fender amps can tolerate an impedance mismatch from -50 percent up to +100 percent.
Pots and jacks. Fixing scratchy pots is a common task for all amp owners and is usually solved by a rotating exercise that freshens up the oxidized metal surfaces inside the pots. If it’s sticky, get yourself a contact cleaner like WD-40 and spray inside the pot.
“When you get more advanced, you can calculate specific bias currents based on measured plate voltages and a specific tube’s dissipation factor.”
Reverb tank. Reverb failure is common and often explained by bad phono cables or plugs. It is easy to learn the mechanics of the reverb tank by simply unplugging everything, changing cables, and opening the reverb tank to look for detached reverb springs and broken soldering joints.
Replacing power tubes and adjusting bias. A power tube requires a correct combination of plate voltage and bias current to operate safely and at full power levels. Since there are different tubes, component drift/variation in caps and resistors, and different voltages in houses and buildings, some tube amps come with an adjustable bias pot.
You need a bias-meter tool to measure bias currents or voltages when replacing power tubes, or diagnosing an amp that lacks clean headroom or has nasty distortion. When you get more advanced, you can calculate specific bias currents based on measured plate voltages and a specific tube’s dissipation factor. Until then, a general rule is to aim for 35 mA for 6L6 amps (except for the Vibrolux, which has a higher bias current at 38 mA) and 22 mA on 6V6 amps. Use your ears, too!
Caps. Old, dried-out electrolytic capacitors should be replaced for both tone and safety’s sake. With a soldering iron, it’s very easy to replace each of the 10 to 11 caps in a black- or silver-panel Fender amp, one by one. Be careful with the polarity, and make sure to drain out all DC voltages (see “Safety,” above).
Preamp tubes. Replacing preamp tubes is easy—no bias adjustment is required. Replacing preamp tubes systematically can solve your problem or help you narrow it down. You then need to learn the function of each preamp tube and which channel they serve. If you want to modify your amp, simple tube swaps can easily change the behavior of your amp, like altering the threshold where your preamp or power amp starts breaking up.
Transformers. I rarely come upon damaged transformers, but sometimes I swap them to get a bigger and firmer bass response, or if I want different speaker impedances. By looking at the soldering job, cutting of isolation, wire lengths, and layout, I can easily spot an amateur’s work. To prevent all kinds of safety, hum, and interference problems, a transformer replacement must be done cleanly and robustly. The risks are high.
Understanding the signal chain. If you have more complex problems that tube replacement doesn’t solve, you must learn how to inspect an amp and isolate problems to various circuit functions. This will require you to learn some circuit theory and schematics. The good news is that since Fender amps are all very similar, once you learn to work on one, you can easily learn to work on them all.
