Not too long ago, you could easily find low asking prices on silver-panels of all types, earning them a designation as vintage amps for working musicians (prices have gone up, but you can still find a deal with a little effort). Yet thanks to those more affordable tags and their reputations, the years haven’t always been kind. These amps have been put through the ringer and subjected to their share of mods: everything from tweaks to increase midrange to ill-advised attempts to turn them into Marshalls and Voxes. Still, so many have survived the test of time—a testament to their durability.
“What we see today is from 50, 60 years of things becoming the industry standard. Back in the ’50s or ’60s, everything was new. They were just throwing things out there.”—George Alessandro
If you own a silver-panel model, you know that there’s a lot of subjective information floating around between the internet and our local amp-repair shop. If you’re not a tech, and you just want an amp that works well and sounds good, it can be a lot to unpack—suggestions about mods, restorations, and other tweaks can really leave your head spinning. It might seem like the easiest path is to never change anything and just fix what’s broken when it’s time to service yours, but that’s not always possible. Vintage examples of these amps have been rocking for so long that many of them are likely to need quite a bit of maintenance or have received extensive servicing over the years, and possibly not at the highest level.
So, when it comes time to fix your amp, what’s the best way to proceed? Do you restore your amp to factory spec? And will you even like the way that sounds? Considering how much time has passed, there’s a good chance it could make for a dramatic difference. And are some modifications to the circuit in order?
I’m no tech. I’m just a player who has an appreciation for these amplifiers and has owned my share of ’em. So, with all these questions in mind, I hit up a couple experts who know their way around a Fender amp in order to set the record straight on how to proceed with servicing our silver-panel amps and getting the best, most reliable tones out of them.
The author’s beloved 1971 Deluxe Reverb shows some wear after 51 years of heavy use. Except for a replaced speaker—now a Celestion Vintage 30—this amp is up to original spec.
Through 1965, Fender kicked out one iconic, revered amp design after another. After CBS took over, those circuits slowly changed over the course of the transitional late-’60s “drip-edge” era of amps. By the ’70s, the entire line had evolved into the silver-panels. This was Fender’s first era to really draw significant negative feedback from players. (When’s the last time you read a piece about modding a tweed Deluxe!?) One big point of criticism is that, during this phase, the company was looking for cheaper ways to build their amps—choices often blamed on the accounting department rather than their engineers—which affected everything from speaker quality to the type of wire used inside the circuits.
But there’s more to it than just skimping on parts. “They were just trying to keep up with the times,” explains George Alessandro of Alessandro High-End Products. In addition to his own amps, which are famously used by artists like Derek Trucks, Eric Clapton, and John Mayer, Alessandro also rebuilds plenty of vintage models for some of those same players. While some parts were of a lesser quality in the silver era, he points out that “Fender’s raw materials were still relatively good quality. By the ’70s, the caps were still good, the transformers were still authentic, the chassis were still right.”
“I find that the silver-panel amps, even if they are 10 years newer than the black-panel amps, are usually in much worse condition because they are stacked away in a moist basement or garage.”—Jens Mosbergvik
A big reason that silver-panel amps don’t live up to the reputation of their older siblings is that “their focus was more on getting output than tone.” Alessandro explains, “By the mid-60s, things were getting louder. PAs were just coming into play. Concerts were getting bigger. So, amplifiers had to get much larger and louder.” This eventually amounted to larger transformers in some models and other changes to boost power and bass response.
“At the time, there was no set rule,” he continues. “What we see today is from 50, 60 years of things becoming the industry standard. Back in the ’50s or ’60s, everything was new. They were just throwing things out there.”
But the lesser-than reputation of the silver-panel amps is often not exclusively about choices that Fender made back in the ’70s. It’s also about how these amps have been treated in subsequent decades. Once “pre-CBS” became a revered term, that solidified the reputation of anything Fender built before 1965, and those amps were often treated differently than the silver-panels. “The thing with silver-panel amps,” says Jens Mosbergvik, PG’s own Fender expert and author of our Silver and Black column, “is that they have been less looked after than black-panel amps because they were considered cheap amps. I find that the silver-panel amps, even if they are 10 years newer than the black-panel amps, are usually in a much worse condition because they are stacked away in a moist basement or garage.” With its lesser status, a silver-panel amp is also more likely to have been either serviced poorly or modified.

Nowadays, plenty of players love silver-panel amps. They might not always deliver the hallowed tones of their pre-CBS siblings, but these models certainly hold their own when stacked against many modern amps that command similar prices. If you own one that hasn’t been restored, when you service it or take it to get serviced, you’ll have some decisions to make.
The most important thing to do is consider your expectations. Los Angeles guitar tech Colleen Fazio, who posts extensive and informative vintage amp repair and restoration videos to her YouTube channel, calls herself a “minimally invasive” tech and says, “I always tell people, ‘If you want your amp to sound like a different amp, you should probably just get a different amp.’ Because each amp is designed to do its own thing.”
Watch the author test out these two vintage gems.
“My philosophy with vintage amps is do no harm. I don’t like mods,” says Alessandro. “I’m really against mods, because almost 100 percent of the time it ruins what something is supposed to be.” He also warns against any sort of modification that will change an amp’s intended character. “I do more un-modding of vintage amps than you can imagine. A Deluxe Reverb is not going to be a tweed Deluxe. It’s not going to be a little Bluesbreaker. It’s gonna be a Deluxe Reverb. Try and make it the best it is supposed to be.”
Alessandro advocates looking at the changes made by Fender in the silver-panel era with perspective and hindsight. “That circuit from ’64, ’65 is right,” he says. “So, when Fender started changing it through the years, they were making it less right.” When it comes to restoring a silver-panel amp to black-panel specs, Alessandro doesn’t necessarily consider that to be a mod, but, rather, “restoring from what their engineers changed and making it what it’s supposed to be.” He adds, “It’s kind of like an old computer. What do you do when your new software doesn’t work? You revert back to the old one.”
“I always tell people, ‘If you want your amp to sound like a different amp, you should probably just get a different amp.’ Because each amp is designed to do its own thing.”—Colleen Fazio
Whatever you’re doing, whether it’s servicing or making changes to the circuit, Alessandro stresses using the correct components. “People go in there and replace all the parts,” he says, “because this resistor is supposed to be 100k, and it’s reading 112. But it’s not that it’s reading 112 that’s the problem. It’s when they replace it with a 100k resistor and it’s not the right type.”
To get the most from your amp, Mosbergvik says “there are only a few solid things you should do that will really improve the amp in terms of tone.” While different models and years will have their own idiosyncrasies—including the push-pull boosts, master volumes, and larger transformers found in models from the latter part of the decade—here are a few things you or your tech might consider.
Mosbergvik’s favorites for amps with 10" speakers are Weber 10A100s ($114 street), which he says are “pretty close to the Jensen P10R or CTS alnicos in 1964 black-panel Super Reverbs,” or Weber 10A125s ($119 street) “for a tad more punch and bigger/cleaner bottom end.” For ceramic speakers, he likes Weber’s 10F125s ($108), which he says are “like the CTS ceramics in some ’65 Super Reverbs.”
For amps loaded with 12s, George Alessandro specially designed the GA-SC64 ($144 street) with Eminence to capture the black-panel-era sound.

By the ’70s, Fender switched all their fixed bias amps from a standard bias control, which allows users to raise or lower the bias on the power tubes but requires a matched pair, to a balance-style control, which accommodates non-matched power-tube pairs yet might not give those tubes the power they need. This creates bigger problems than simply purchasing a matched pair of power tubes and can have a negative effect on an amp’s tone.
“You can re-wire the control to be like the ’60s control, so you’re adjusting the bias,” says Fazio. “It’s a pretty simple re-wire. I would probably include that with a service. You’re not replacing any parts, you’re just re-wiring the configuration.”
Look at the sides to spot the differences. This Super Reverb has a screwed-in style baffle board.

Early in the ’70s, Fender switched from using a screwed-in baffle to a glued-in baffle, so removing them can be tricky on the latter models. Mosbergvik says the glued-in design sounds “unbalanced” to his ears and points out that it is possible to switch back to the early screwed-in style if you’re already removing the baffle. “You’ll need to work to get it screwed in,” he explains. This includes adding supports to screw the baffle into. “It’s a lot of dirty work.”
If the baffle needs to be replaced, you’ll have to decide between a plywood baffle, a popular choice for many players who believe it changes the tone for the better, or stick with the original particle-board style, which is consistent with both silver- and black-panel models.
All that is easy enough for us non-techs to wrap our heads around. But Fazio points out there are some finer differences to be found by looking at schematics.
The coupling capacitor is in the part of the circuit that connects the preamp signal to the output section. “A bigger value in the silver-panel amps increased the bass response. If you want tighter bass like the ’60s amps, you lower the value of that capacitor back to the ’60s specs, which is .001 µF, and a lot of the silver amps are .01. There are some exceptions, but those are common values to find.”
She also points out that the values of the plate resistors on the phase-inverter tube were lowered in the silver-panel amps to reduce gain, and those can be changed to original spec.

It’s always good to remember that any change you make to your amp will affect the way it sounds and feels. If you have an amp you already like, you should especially keep that in mind and don’t feel any pressure to make changes that aren’t necessary. “If it has been modified and you like how it sounds, that’s cool. Silver-panel amps sound really good as they are, and I’ve heard really good modified ones, too,” says Fazio.
If you’re looking to purchase an amp that has been modified, it can be helpful to take a look at the circuit, when possible, even if you’re not a tech. Mosbergvik suggests inspecting to see “if it’s done tidy and properly, with twisted wires, and if the soldering work is done properly—the wires are cut to correct length, they are soldered with enough lead, etcetera.” This will at least help you decide the quality of work that has gone into the amp over the course of its decades of servicing.
One of the great things about these vintage specimens is that they’re easy enough to work on and it’s not hard to source parts. “Fender amps are so nice and so well designed,” says Fazio, “it’s pretty easy to bring them back to stock if you want to.” So, there’s a good chance you’ll be able to keep your amp in good working order for many years to come. And with some of these tips, you’ll be able to have it sounding better than ever.

"It’s, of course, almost impossible to crystallize something in words that is beyond words. I think the combination of music and words is so much more powerful than simply the written word. If you can get those two things in balance, it can almost make you understand what is beyond understanding.”
The band went on hiatus after that show, and Wilson furthered the pursuit of his solo career (which began in 2008 with the release of his debut, Insurgentes). After a while, fans began to assume that waiting around for a Porcupine Tree reunion was a lost cause.
“I was quite a big contributor to that, too,” Wilson admits. “I would say to people, ‘No, forget it, we’re not coming back.’” But it wasn’t true. “I was telling a white lie just to get them to focus on what I was doing at that point. But actually, behind the scenes, we were working toward something that would eventually herald the return of the band.”
Porcupine Tree’s 11th full-length studio album, Closure/Continuation, marks that return. With the 65-minute, 10-track record, Wilson, drummer Gavin Harrison, and keyboardist Richard Barbieri offer a new collection of compositions that build on the band’s classic sound with a reinvigorated, visceral pulse.
Opening with the guttural, aggressively percussive bass line on “Harridan,” the album navigates through a series of kinetic musical worlds that are, in balance, both pensive and turbulent. The second track, “Of the New Day,” has a plaintive refrain taken from its title, and later on in the album, the haunting, subtly shapeshifting “Chimera’s Wreck” moves through tones of disquiet to create a nearly 10-minute narrative that’s both cerebral and emotive. Other standout tracks include the ominous “Herd Culling,” and the sinister “Rats Return.”
It’s elusive what exactly makes the record something that moves the band forward. It might be the amorphous arrangements, which stay accessible as they seem to breathe even more freely than past works, or the seamless concatenation of foreboding, hopeful, and furious overtones, or the strength in the voice that ties together each of the self-contained, emotionally complex, often dystopian scenes. But in their time away, what Wilson calls the band’s “creative core” seems to have evolved.
“I would say to people, ‘No, forget it, we’re not coming back.’”
Although Porcupine Tree never actually disbanded, there was a gap between 2010 and 2012 where they weren’t seeing much of each other, at least not for composing purposes. Then in 2012, they began a 10-year gestation of material that would end up becoming Closure/Continutation. Their writing sessions were sporadic, says Wilson: In the beginning, they would get together for just a few weeks at a time every other year.
“Part of the reason for that, I think, was that we didn’t want to feel any pressure in making a Porcupine Tree record,” he shares. “A lot of people assumed that we didn’t exist anymore, and I kind of liked that because it meant that we could work on the record in a complete vacuum with no pressure, no expectation, no deadlines.”
The 2020 lockdown motivated them to finally knuckle down and bring the record to completion, but they wouldn’t have gone through with releasing it if they didn’t feel as though they were doing something new. Part of Wilson’s jadedness at the end of that 2010 tour was because he felt, despite its relative chart success, that their last record, The Incident, was largely uninspired. “I felt like we were on a creatively downward trajectory where the music was no longer getting better,” he says. “In fact, it was beginning to sound a bit same-y. And it’s always been very important to me and the band that every record has a sense of evolution from the previous record.”

With the new album, he feels they’ve succeeded in that respect. “I’m very proud of the music, and I think it’s some of the best I’ve ever made,” he says. “Time will tell how the album fits into the catalog—it’s not something you can judge in such a close proximity. But right now, I’m fairly confident this will become one of the more popular and successful things I’ve ever done in my career.”
The band’s followers might notice that longtime bassist Colin Edwin doesn’t appear on the album. Rather, Wilson plays bass througout. He says filling that role wasn’t at all meant as a slight to Edwin but was a result of how the music came together. “It was just a very natural thing for me to try something different rather than picking up a guitar,” Wilson says. “And we ended up writing so much of the record in that way.”
“A lot of people assumed that we didn’t exist anymore, and I personally kind of liked that because it meant we could work on the record in a complete vacuum with no pressure, no expectation, no deadlines.”
Wilson’s guitar-minded approach to the bass produced a style that diverts from more predictable patterns. “I play bass like a guitar player,” he comments. “I play a lot of stuff high up, I play a lot of melodies, I play a lot of chords, and I don’t perhaps play like a traditional bass player would play.”
Writing on bass helped make the album more groove- and riff-oriented, and less polyphonic overall than past records. The newfound approach also gave Wilson a refreshed outlook on composing. “I’ve been writing on the guitar for the best part of 25 years. And frankly, when I pick it up now, I’m not sure what else I’ve got left to do!” he shares. “But when I pick up the bass, or I go to the keyboard, suddenly there’s so much more that I’ve never done before. I surprise myself more when I play them.”

Aside from acoustic strumming and fingerpicking on a few tracks, and edgy riff emphasis on others, the guitar mostly takes a backseat on the album. Wilson supports his arrangements with some solos that embody his quintessential feel for the instrument, but all in all, it’s apparent that the bass was truly the guiding force on Closure/Continuation.
In July, Wilson released another project: a 320-page autobiography entitled Limited Edition of One. Its subtitle, How to Succeed in the Music Industry Without Being a Part of the Mainstream, perhaps serves as its thesis. His story is that of someone who’s had success without ever having quite broken through, and that angle is exactly what helped him decide it was worth sharing.
“I always thought it would be a very boring book. I thought, ‘Well, there’s no book to be written because I don’t have any of those stories about being on the road and drugs and religion and groupies. I’m just a nerd that fell in love with the magic of making records.
“Then the guys at Hachette [the book’s publisher] pointed out to me, actually, that’s why a book on me would be interesting. Because that traditional rock ’n’ roll hedonistic thing … people are bored with that story because they’ve heard it so many times. At that point I became more convinced that maybe I did have a story to tell.”
Porcupine Tree’s new release, Closure/Continuation, had a gestation period of over a decade. The band hasn’t released an album since 2009’s The Incident.
“Love him or hate him, Kanye West is an incredibly innovative producer.”
He also writes, in his book, that he doesn’t see himself as a guitar hero. “I always feel fake and slightly embarrassed when I’m being interviewed for guitar magazines.” At the beginning of our conversation, Wilson says, “I’ll be very boring if I talk about guitars, because I don’t know much about them, to be honest.”
While many consider Wilson exclusively a progressive rock artist, his latest solo record, The Future Bites (2021), is but one of his works that refutes that notion, as it sits comfortably in an electronic or synth-pop category. Given that, it may not come as a surprise that when asked which musicians he thinks are truly progressive today, he’s quick to praise modern hip-hop artists.

“Love him or hate him, Kanye West is an incredibly innovative producer,” he says. “Then there’s Kendrick Lamar. When you listen to the way they structure music and the way they make music, it’s so alien to the ear of people that grew up with rock music. I think that’s a really good thing, and that’s why we should listen to it.”
Wilson is less certain on how to make those kinds of innovations in songwriting, or how creative inspiration works: “I’ve no fucking clue.” He draws inspiration from all sorts of things, but also often goes into the studio and just bangs his head against the wall with nothing to show for it. “Yeah, [creative droughts] are really depressing. I get really down when I go through a period where I can’t create anything,” he shares. “I always come to the conclusion that, ‘Oh shit, I’ve written the last song I’m ever going to write. I’ve got nothing left. The well is dry.’ But I also manage, touch wood, to prove myself wrong. What I do is I carry on going to the studio, and I carry on hitting my head against the wall. I have a very strong work ethic.”
“It’s, of course, almost impossible to crystallize something in words that is beyond words,” he continues, reflecting on the ethereality of songwriting. “I think the combination of music and words is so much more powerful than simply the written word. If you can get those two things in balance, it can almost make you understand what is beyond understanding.”

Talking to Wilson, his affability stands in contrast to the frequently dark and lachrymose themes heard in Porcupine Tree’s music. He explains that, for him, writing sad songs is like an exorcism or an unburdening of his own sadness.
“Miserabilism and melancholy … I’ve always found such a beautiful thing. It’s a profoundly magical thing if you can create empathy through focusing on some of the more negative feelings that we all share. And that’s why I still think that music, where on the surface it might be sad or melancholic or depressing, has the potential to be something incredibly uplifting and beautiful for the person who experiences it.”
Wilson leads Porcupine Tree in a performance of “Lazarus” from the 2005 album Deadwing, illustrating his penchant for introspective, melancholic ballads that find their place among the band’s heavier material.
