Since forming to help early garage rockers the Kingsmen bring their hit āLouie Louieā on the road, Sunn amps have roared behind everyone from Jimi Hendrix to Leslie West to Kurt Cobain to the doom-metal act that bears their name. After laying dormant for decades, the brand is back and the new team promises to live up to its legendary reputation.
āHave you ever considered covering āLouie Louie,āā I ask Stephen OāMalley over Zoom. The doom-metal guitarist and half of the band Sunn O))) is a native of Seattle but has lived the past 20 years in Paris, France. āI see where youāre going with this,ā O'Malley chuckles, and says, ābut weāre not a rock ānā roll band. Still, the Kingsmen and Conrad Sundholm building a bass amp for his brotherāthatās a legendary Northwest story.ā
In 1963, the Portland, Oregon-based Kingsmen found themselves near the very top of the charts behind what would become a garage-rock standard, the immortal āLouie Louie.ā The Kingsmenās bass player, Norman āNormā Sundholm, and his brother, Conrad Sundholm, simultaneously became seminal figures in developing an amplifier line that would eventually become the sonic foundation of the doom-metal music artists like Stephen OāMalley play. In between, the amps became a crucial sound in classic rock.
The Kingsmenās version of āLouie Louieā [written by Richard Berry] sat in the Billboard Hot 100 chart for 18 weeks, peaking at number two. Suddenly, everyone wanted to see the band live, and they hit the road, playing on stages all over the country. PA systems geared toward high fidelity for rock ānā roll concerts were still several years away, and Norm Sundholm needed a bass amp that could stand up to the rigors of the road and be loud and clear enough for the concert halls and gymnasiums hosting the Kingsmen.
Normās brother, Conrad, was a high school physics teacher and an electronics wizard. The siblings rolled up their sleeves together to build a bass amp for the Kingsmenās first big tour. According to an interview Norm gave to NAMM in 2019, they first modified a 26-watt Fender Bandmaster, replacing the speakers with JBLs and adding a preamp stage using an off-the-shelf amplifier manufactured by Dynaco. Using their surname as inspiration, they called the 60-watt amp a Sunn.
āHot on the heels of their hit single āLouie Louie,ā the Kingsmen needed more amp power. Bassist Norm Sundholm turned to his brother Conrad, who started the Sunn brand with this early model.

Norm Sundholm declined to be interviewed for this piece, and Conrad Sundholm died in 2021, but his son, Steve Sundholm,fills in what came next: āUncle Norm gave out my dadās number to fans at Kingsmen shows who heard this amp and wanted to buy one. So my dad started getting random calls from people around the country asking how they could purchase a Sunn amp.ā By about 1965, Conrad borrowed $1,300 from his credit union to begin building speaker cabinets and cobbling together new Sunn amps. Partly using Dynaco components and employing JBL speakers, early models included the 100S for guitar and the 200S for bass. Throughout 1963 and 1964, Conrad Sundholm built Sunn amps in his garage.
During downtime from Kingsmen tours, Norm went on the road in search of retailers to carry the Sunn line. While on tour, he met Bill Eberline, an 18-year-old disc jockey from Michigan, and hired him to be the companyās first sales rep. Eberline worked in 18 states east of the Mississippi, setting up retailers. Now 79 years old, Eberline tells me, āFor me, Sunn was a passion, and the reason it was a passion was because the amps and the cabinets were so good. I loved the look on a musician's face when they plugged in for the first time and turned it up.ā The secret, he says, was not only the amplifiersā power and tone, but also the unique design of the speaker cabinets.
āThe speaker cabinets for our bass amp, the 200S, were called rear-loaded, folded-horn, bass-reflex enclosures,ā he explains. āSo the speaker comes in from the back, thereās baffling inside, and the speaker is tuned to the cabinet. So you get the most out of it; youāre getting as much sound off the back as youāre getting off the front. I used to demonstrate it to people using a match. Iād put a lit match in front of the speaker, and it would blow the match out. Other speakers had open backs, so you were losing all that sound. And it gave it an incredible punch. It was the best bass speaker cabinet, at the time, that had ever been built.ā
After sitting dormant for more than two decades, the Sunn brand has been resurrected by a new team that promises to stick to the companyās core construction techniques while addressing the needs of modern players. This cab is classic Sunn.
āWe started going from music store to music store, unloaded them out of the van, and wheeled them into shops,ā Norm Sundholm told NAMM. āIt was a little tough with the franchise Fender dealers, but any competing store was wide open to take the line.ā
It was Bill Eberline who brought one of Sunnās biggest retailers to the party: Mannyās Music in New York City. Mannyās was the epicenter of Manhattanās music retailers row on West 48th Street. About 10 different shops lined the block between 6th and 7th Avenues, making it simple to stumble from one to another. From Jimi Hendrix to Jimmy Page, all the premier guitarists of the day shopped there.
āI used to demonstrate it to people using a match. Iād put a lit match in front of the speaker, and it would blow the match out.ā āBill Eberline
āAt first, Mannyās wasnāt interested,ā Eberline recalls. āAnd Manny himself eventually kicked me out of the store; I was hanging out there all day with this big amplifier. But as I was leaving, one of his competitors across the street saw me and the amp, and he called me over. He said to me, āListen, kid. [Eberline was 20 years old at the time.] Have your factory ship me a bunch of empty boxes with the Sunn logo.ā And I did! He put these out on the street in front of his shop like they were trash, as if he had ordered a bunch of our amps.ā Soon after seeing the boxes, Mannyās placed an $80,000 order. That huge sale, in 1965, gave Sunn enough capital to move into a bigger manufacturing space, which Steve Sundholm tells me was his grandfatherās garage. āIt was big, like the size of a boathouse,ā he says.
Inside the garage, Sunn built tube guitar and bass amps such as the 60-watt 100S and 200S, and the 120-watt 1000S and 2000S, as well as the solid-state 100-watt Beta series and the 300-watt (at 2 ohms) Coliseum. The amps quickly became known for their volume, punch, and ability to deliver an articulate bottom end, and they became increasingly more visible on high-profile stages. Noel Redding, playing bass in the Jimi Hendrix Experience, used six Sunn speaker cabinets and three amp heads in June 1967 at the Monterey Pop Festival. Sunn amps were also seen and heard in the backlines of Led Zeppelin, the Who, and Cream. Hendrix most likely purchased his Sunn gear at Mannyās Music. Eberline remembers, āJimi played through two of our most powerful amps daisy-chained togetherāthe 1000S, double the power of the regular [100S] amp, and it used four KT88 tubes. He put that through four Sunn cabinets with two 15-inch speakers in each cab.ā
āThe Model T, one of the most coveted amps to bear the Sunn name, was created during Tom Hartzellās ownership of the company. This is one of the many employed by Sunn O))) guitarists Stephen OāMalley and Greg Anderson.

In August 1969, Eberline trucked Sunn amps to Woodstock, where they appeared behind Felix Pappalardi and Leslie West of Mountain on their Saturday evening set. That got Eberline into trouble. The roadies at Woodstock kept all the loaned amps, Sunn lost the inventory, and Eberline was fired.
James Lebihan is the CEO of the newly relaunched Sunn brand. He takes the history further, telling me over Zoom, āEverybody used Sunn gearāthe Beach Boys, the Allman Brothers, and the Jeff Beck Group. Even later, bands like Queen used Sunn amps.ā The Rolling Stones considered endorsing Sunn amps. However, according to the book Rolling Stones Gear by Andy Babiuk and Greg Prevost, the Stonesā shipment of amps was damaged in transit, and the endorsement never materialized.
The common denominator for the bands embracing Sunn was the desire for an overdriven tone with a lot of bottom end. In other words, the sound was heavy. Their tone was perfect for early metal and hard-rock artists like Black Sabbath and Mountain. West used a Sunn speaker cabinet to record their iconic āMississippi Queenā at the Record Plant in New York City.
In 1972, a few years after leaving their dadās boathouse-size garage and opening a factory in Tualatin, Oregon, the Sundholm brothers sold their company to a manufacturer named Tom Hartzell. Although a few of Sunnās best models emerged during that periodāincluding the iconic, tube-driven, 150-watt Model Tāthe Hartzell years are considered by many to be somewhat lost. Eberline says, āI left before they sold the company, but those new guys did not know what they were doing, in my opinion.ā Hartzell was not a music-business guy and didnāt quite grasp the industryās economics. Then, in 1977, he perished in a plane crash.
The magic of the Sunn Beta Lead and Bass amps was in their preamps. Hereās a current rackmount-ready version of that famed preamp unit, from the new Sunn factory.
Not much happened after Hartzellās passing, and the brand lay dormant until Fender purchased Sunn in 1985, just as punk rock and metal split into genres, including hardcore, doom metal, and grunge. Sunn amps were embraced by guitarists like the Melvinsā Buzz Osborne and Nirvanaās Kurt Cobain. Thatās when Stephen OāMalley first became aware of them. āI was into hardcore and death metal,ā he remembers. āI was15 years old, and I saw the Melvins. They burst my brain open. Joe Preston is on bass, and Buzz Osborne is playing two full Sunn stacks with two Sunn Beta Leads. That was the first time I heard loud guitar where it was ripping the air apart, and you feel it in your body.ā OāMalley also recalls seeing Northwest heavy rockers Karp using a Model T, and he praises that ampās ability to be adapted to a genre like doom metal.
āWe modify them,ā he explains. āWe put in special tubes, and weāre able to change the bias of the amps. We take out what we donāt need, like the line out, and we take out the circuit breaker and replace it with a fuse. The Model T allows me to have less breakup in the preamp section and more headroom. It becomes more about speaker distortion and power-tube overdrive than high-input gain.ā
The essential, blue-ribbon quality of the Model Tāeven unmodedāis how it works with overdrive and fuzz effects. The extraordinary transparency and headroom of these amps allows the sonic character of these pedals to take on enormous, growling dimensionsāso they become almost supernatural versions of themselves.
Was it only the tone driving these later Northwest-based bands toward Sunn Amps? Perhaps not. Sunn had long been an Oregon company, so there were a lot of cheap, used Sunn amps sitting around in guitar shops from Portland to Seattle. Lebihan explains it this way, āWhen these guys were getting started, and they were teenagers, and they were in school, and they didnāt have any money, they could find these Beta Leads and Model Ts in pawn shops.ā Stephen OāMalley tells me that his partner in Sunn O))), Greg Anderson, found his first Model T at a swap meet in Seattleāa vinyl dealer left it sitting under a table of records.

The steep headroom, high-gain, tube-driven 100S, 200S, Model T, and solid-state Beta line of bass and guitar heads are now considered the pinnacle of the original line. OāMalley claims some amount of credit for this: āTheyāre a mythical amplifier now, but I donāt know if they would be if it werenāt for our band and the scene around our bandālike Wino Weinrich from the Obsessed, he played them, too.ā

Until recently, Fenderās ownership would not be considered a new golden age for Sunn; not much happened. Fender did drop a Model T reissue, but that amp shared virtually none of the same circuitry as its Hartzell-era predecessor. Strangely, Fender actually built some electric guitarsāusing the Mustang and Strat namesāoverseas under the Sunn brand. But overall, the brand languished, making the vintage gear rare and sought-after in the used market.
Lebihan tells me that many have tried to get Fender to relaunch Sunn since the brand was discontinued in 2002. Still, it was only when he came to the table in 2023 and brought Mike Eldred and Steve Skillings with him that Fender executives finally sat up in their chairs and made a deal to relaunch Sunn. This triumvirate brings decades of musical marketing skills to the party: Lebihan had a background in tech before becoming a serial entrepreneur in the music world; Eldred was on the team that put the Fender Custom Shop on the map in the mid ā90s; and Skillings came from a background at Bose, where, among other things, he was on the Bose L1 teamāthe group that created the ubiquitous skinny-speaker PA systems popular with buskers, garage jammers, and wedding bands.
Together, this team has big plans for Sunn, and early on they ran a Wefunder campaign in which 288 enthusiasts were able to support the new Sunn company in exchange for discounts on amps and branded swag like t-shirts and pint glasses. The cash, says Skillings, is fueling costs for tooling and other early manufacturing requirements. āThereās a lot of costs associated with ramping up this kind of product,ā he notes. āJust to do a mold for a knob, for example, costs $5,000.ā
āThere are cheaper ways to manufacture these things that would make it ānot Sunn.ā And I see them going out of their way to recreate it as faithfully as possible without making it the cost of a mortgage payment to the customer.ā āSteve Sundholm
And theyāre preparing to drop new generations of amps in the near future. Not only will Sunnās popular tube amps be back, but theyāre also creating solid-state bass heads and new cabinets. And they plan to push well beyond what Sunn has been known for for 60 years. Mike Eldred is visibly excited when he says, āWeāve got a Beta combo amp coming up for preorder very soon. And weāre going to continue pushing into the combo market and beyond. You have a lot of folks now who donāt want to lug around a heavy 150-watt amp and products are coming out now that reflect that, where your amp is on your pedalboard. Weāre going to go after that market aggressively.ā
The essence of the modern Sunn 100S.
One thing everyone is curious about is the future of the Model T, the amp most heavily embraced by OāMalley, Anderson, and other doom-metal axe grinders. Thatās something the new Sunn team is rethinking very carefully. The Model T offers a singular tone, but in todayās live music environment, where portability and low-wattage amps rule, itās a bit of a dinosaur. Eldred says, āThereās no reason why you canāt take the tone stack of a Model T and pare it down into something like a 20-watt version of the amp.ā
Steve Sundholm became a board member of the new Sunn brand after his dad passed away. He tells me that at the end of his dadās life, Conrad knew Sunn was coming back. āHe told me, āMan, I hope they do it right.ā Not āThey better do it right,ā just āI hope they do.āā Steve is convinced that his dad would be proud of this relaunch. āIāve seen their plans,ā he says, āand I really feel like they are going above and beyond to do it right. For example, theyāre building the same closed-back cabinet style as the vintage speakers. There are cheaper ways to manufacture these things that would make it ānot Sunn.ā And I see them going out of their way to recreate it as faithfully as possible without making it the cost of a mortgage payment to the customer.ā
OāMalley, who considers the amps in his backline āmembersā of his group, also looks forward to checking out the upcoming line and what the new Sunn team is doing. He says, āI understand that they are building the new amps to original specs; Iām really curious about them.ā Even still, a āLouie Louieā cover from Sunn O))) to connect the dots probably wonāt materialize.
Thereās no doom-metal band out there I can find whoās covered the Kingsmenās signature tune, although both Motƶrhead and Black Flag have taken great, heavy shots at it. Perhaps they may have even used Sunn amps in the process. As Sunn rises again, illuminating the musical landscape once more, the chance for new riffs and powerful sounds to come from this brand is brighter than ever.
Wondering how to get the most out of your Fender amp? Our columnist shares his top amp-and-cab combinations to boost your tone and volume for any situation.
Let's talk about speaker cabinets. If you have read my previous columns or been to my website fenderguru.com, youāll know how much I value knowledge about speakers. Speakers affect the tone and volume vastly in guitar amps, and an extension cabinet is a smart and cheap way to get your tone right at practice, live gigs, or in the studio. In this column I will share my favorite amp and speaker cabinet pairings. As usual, I will refer to the classic black- and silver-panel Fender amps, which many of us enjoy.
I have plenty of extension cabinets lying around at home, including many that I have built myself. I use them across all the amps I have, with both combos and piggy-backs. Some are intended for British-style cranked tones, and some American vintage-style. Some cabinets have efficient and chunky speakers that can double the punch and spread on large stages, which I use when the speakers in my combo amps are not enough. More (and louder) speakers enable me to create a representative guitar tone on stage that everyone can hear well. āSound good, play goodā is one of my philosophies. Extension cabinets can serve other purposes too, such as lowering the volume for more breakup or mixing several speakers for a more complex and rich tone. There are so many interesting tone flavors that you should experiment with.
āThe impedance mismatch gives me Hendrixās JTM45 tones at reasonable volumes.ā
Here are my all-time favorite Fender amp and cabinet pairings. All speakers are 8-ohm and wired in parallel, if not explicitly mentioned otherwise.
Black-Panel/Silver-Panel Bassman and Bandmaster
These ampsā flexible 4-ohm output transformers allow many different speaker configurations. The original 2x12 cabinet is very loud and chunky. If you use a 3x10 or 2x10 open cabinet with modest, vintage-style speakers, you will sound more like a Super Reverb, Vibrolux, or tweed Bassman. The 50-watt Bassman can push a 2x15 or even a 4x12 (ideally 16 ohm, with 8 ohm as second best) if you are in a āWhoās your daddy?ā mood.
My favorite cabinet with the Bassman is a 1x12 semi-closed cabinet loaded with an Eminence Reignmaker with a 9 dB built-in attenuator. The impedance mismatch gives me Hendrixās JTM45 tones at reasonable volumes.
Champ and Blues Junior
In their combo chassis, these amps can sound small and boxy. If you use a 1x12 semi-closed cabinet and disengage the built-in speaker entirely, you can take these amps to gigs. I recommend at least a Deluxe Reverb cabinet to get enough punch and spread.
Deluxe Reverb
With the 22-watt Deluxe 1x12, you can add an additional 1x12 for more spread and punch. If you replace the ampās 6V6 power tubes with 6L6s, you have more powerāroughly 30 wattsāand can add a 1x15. Always remember to adjust bias when replacing power tubes.
Princeton Reverb
The small output transformer and inefficient phase inverter circuit limits the Princeton Reverbās dual 6V6s to only 12 watts, with a flabby, loose low end. Therefore, I find the Princeton too weak to add an extension cabinet unless you disengage the built-in 10" speaker. Then it makes sense to use a 1x12 or 1x15 semi-closed cabinet for more punch and spread. This produces a wonderful, warm tone with significant breakup at modest volumes. A cool trick is to pull both 6V6 tubes and insert a single 6L6 for class-A operation and lots of distortion. When I use the 1x12 Eminence Reignmaker-loaded cabinet mentioned earlier, I get full tube distortion at almost bedroom level.
Vibrolux Reverb and Pro Reverb
The flexible 4-ohm configuration makes these amps perfectly suited for a 1x12 or 1x15 extension, for more spread and a mix of tone flavors. If I want to go really big, I disengage the inbuilt vintage-style speakers and hook up my Bassmanās 2x12 closed cabinet. Be aware that the small output transformer of these amps will limit the low end response.
Vibroverb
The undersized power transformer limits this ampās low-end response. I donāt fancy adding another speaker because it gets too flabby with a 100 percent impedance mismatch.
Super Reverb
I rarely use extension cabinets with the Super Reverb because itās already loud and punchy. On the contrary, I often disengage two of the four speakers to lower the clean headroom and volume. If you need more spread and send the sound in several directions, you could easily add a 1x12 cabinet and get a balanced and reasonable distribution of the ampās 40 watts to all five speakers.
Twin Reverb
For those crazy players who need more from an 85-watt Twin, you can add an additional 1x15, with a resulting 50 percent impedance mismatch. Adding a dual 12" or 15" cabinet wonāt make it louder since the impedance mismatch increases to 100 percent, which is the maximum I recommend.
