The Swedish prog-metal sorcerers dish on their longstanding PRS ties and uncover why they traded traditional tube amps for swappable high-gain Synergy modules.
Holding down lead guitar duties in Opeth since 2007, Fredrik Ć kesson knows his way around the fretboard. And before the bandās first Ryman performance, the self-admitted āgear dorkā shows off the cavalcade of PRS 6-strings he and singer/guitarist Mikael Ć kerfeldt use onstage, explains the bandās move from tube heads to miniature modules designed by Dave Friedman and Steve Vai, and demos the core colors of his live tone.
Fredrik Ć kesson has long been associated with single-cut guitars. His time with Arch Enemy and Krux saw him rock ESP Eclipse models and when he teamed up with Ć kerfeldt he joined the PRS squad. (He was even honored with a signature SE single-cut in 2011.) And one of his favorite studio tools (as noted in our 2014 interview on Pale Communion), is a 1955 Les Paul Junior with P-90s. His current No. 1 is this PRS single-cutāa P245 that is favored because it allows him to blend in piezo tones for the bandās acoustic or quieter sections while still blowing smoke through the humbuckers during their heaviest parts. All of his guitars are strung up with DR Veritas strings, gauged .010ā.052.
Hereās another PRS P245 for Fredrik Ć kesson who goes with this one on the bandās brutish songs because it has their \m/ (Metal) pickup in the bridge position.
For the low-tuned (DāAāDāFāAāE) ripper āReverie / Harlequin Forestā off Ghost Reveries, Fredrik Ć kesson rides this longer-scaled (25") PRS P22.
āNepentheā from Heritage contains jazz-fusion elements, so Fredrik Ć kesson plays this PRS Mark Tremonti signature with a recessed trem so he can unleash his inner Allan Holdsworth. He used to swap out the stock pickups for Seymour Duncans (JB in the bridge here), but this is the only guitar that doesnāt have the originals in it.
Fredrik Ć kessonās above PRS P24 is now a touring backup but still receives plenty of studio action as he loves how it sounds as a lead instrument.
Founding singer/guitarist Mikael Ć kerfeldt spends most of the night on this custom white PRS P24 with a vintage (fatter) profile neck. He uses Thomastik-Infeld Power-Brights (.010ā.045) and Dunlop Nylon 1 mm picks.
Mikael Ć kerfeldtās newest PRS P24 is this bodacious green one.
And for āSorceressā (tuned AāAāDāGāBāE), Mikael Ć kerfeldt employs this PRS McCarty model.
If youāve seen Fredrik Ć kesson with Opeth, youāve seen him shadowed by stacks of traditional, 100-watt tube heads like a Blackstar Series One 100 or a Marshall JVM410H. For recent fly gigs, the guitar tandem needed a smaller, lighter solution and the Synergy tube modules lent themselves as the perfect guinea pigs. Those shows went well so theyāve since adopted them into their touring rigs where theyāre constantly fine-tuning the module pairings. Currently, Fredrik is going with the Steve Vai module and the Soldano SLO module.
Mikael Ć kerfeldtās current module setup includes a Friedman Dirty Shirley matched with a Soldano SLO.
The brain of Fredrik Ć kessonās stomp station is a MusicomLab EFX-LE loop switcher. For pedals, he has the Strymon Volante, TC Electronic Flashback 2, Xotic EP Booster, One Control Tiger Lily Tremolo, Olsson Amps Fuzztner, MXR Phase 95, Boss OC-2 Octave, DryBell Vibe Machine, and a Dunlop 95Q Cry Baby Wah. As for the non-noisemakers, he has a Dunlop DVP3 Volume pedal to harnesses dynamics, a TC PolyTune 2 Mini keeps everything in check, an ISP Technologies Decimator X squelches extra noise, and a Decibel Eleven Hot Stone powers all the fun.
Mikael Ć kerfeldt takes a simpler approach for his colors with a Fractal Audio AX8 doing most of the heavy lifting aside from a Electro-Harmonix Small Stone phaser and a TC Electronic BodyRez pickup enhancer.

In honor of Paul Reed Smith's birthday today, PRS launches a limited-edition model of Paul's personal instrument.
Introduced on Smithās birthday, February 18, the Charcoal Phoenix Limited Edition is part of the PRS Guitars 40th Anniversary celebration. Only 150 of these instruments will be available worldwide, with each including a 40th Anniversary certificate hand signed by Paul Reed Smith himself.
"When we released the Private Stock John McLaughlin Limited Edition in 2023, I was inspired by its exceptional sound and playability. For the Charcoal Phoenix, I wanted to create something equally remarkable but with a stoptail bridge," said PRS Guitars Founder & Managing General Partner, Paul Reed Smith. "Using chaltecoco for the neck and ziricote for the fingerboard, I achieved an instrument that sustains beautifully and rings with clarity. The deep crimson back and the charcoal microburst top inspired the name āCharcoal Phoenix,ā evoking the imagery of a phoenix rising from fire and ashes.ā
Over the past year, Smith has road-tested this guitar, refining its design and tone. Most recently, he played this model on stage at the late-January 2025 PRS Guitars 40th Anniversary concert at the House of Blues in Anaheim. A deep crimson back contrasts with the Private Stock-grade figured maple top in a charcoal microburst finish. The ripple abalone āOld Schoolā bird inlays on the ziricote fingerboard add a vintage touch.
The Charcoal Phoenix also features the PRS TCI pickups, newly updated for 2025, and EQ mini-toggle switches. The TCI pickups are crafted with American Alnico magnets and slightly modified winding, wiring and electronics specifications. Based on Smithās experience playing this guitar live and in the studio for more than a year, these pickups offer clear tones from spanky single coils to full soapbars. The EQ mini-toggles act as tuned high-pass filters when engaged, removing shelved low end and allowing the high frequencies through for more clarity and musical highs.
Rounding out the details are the PRS Stoptail bridge and PRS Phase III Non-Locking Tuners. The bridge is engineered with curved string slots, brass inserts and steel studs. It is designed to maximize the transfer of the stringsā vibrations through the guitar. The lightweight tuners promote tone transfer for a louder, more resonant instrument.
PRS Guitars is planning a year full of new product introductions. Stay tuned to see new gear and 40th Anniversary limited-edition guitars throughout the year at www.prsguitars.com/40 and by following @prsguitars on Instagram, Tik Tok, Facebook, X, and YouTube.

This National electric is just the tip of the iceberg of electric guitar history.
On a summer day in 1897, a girl named Lizzie Douglas was born on a farm in the middle of nowhere in Mississippi, the first of 13 siblings. When she was seven, her family moved closer to Memphis, Tennessee, and little Lizzie took up the banjo. Banjo led to guitar, guitar led to gigs, and gigs led to dreams. She was a prodigious talent, and āKidā Douglas ran away from home to play for tips on Beale Street when she was just a teenager. She began touring around the South, adopted the moniker Memphis Minnie, and eventually joined the circus for a few years.
(Are you not totally intrigued by the story of this incredible woman? Why did she run away from home? Why did she fall in love with the guitar? We havenāt even touched on how remarkable her songwriting is. This is a singular pioneer of guitar history, and we beseech you to read Woman with Guitar: Memphis Minnieās Blues by Beth and Paul Garon.)
Following the end of World War I, Hawaiian music enjoyed a rapid rise in popularity. On their travels around the U.S., musicians like Sol Hoāopiāi became fans of Louis Armstrong and the New Orleans Rhythm Kings, leading to a great cross-pollination of Hawaiian music with jazz and blues. This potent combination proved popular and drew ever-larger audiences, which created a significant problem: How on earth would an audience of thousands hear the sound from a wimpy little acoustic guitar?
This art deco pickguard offers just a bit of pizzazz to an otherwise demure instrument.
In the late 1920s, George Beauchamp, John and Rudy Dopyera, Adolph Rickenbacker, and John Dopyeraās nephew Paul Barth endeavored to answer that question with a mechanically amplified guitar. Working together under Beauchamp and John Dopyeraās National String Instrument Corporation, they designed the first resonator guitar, which, like a Victrola, used a cone-shaped resonator built into the guitar to amplify the sound. It was definitely louder, but not quite loud enoughāespecially for the Hawaiian slide musicians. With the guitars laid on their laps, much of the sound projected straight up at the ceiling instead of toward the audience.
Barth and Beauchamp tackled this problem in the 1930s by designing a magnetic pickup, and Rickenbacker installed it in the first commercially successful electric instrument: a lap-steel guitar known affectionately as the āFrying Panā due to its distinctive shape. Suddenly, any stringed instrument could be as loud as your amplifier allowed, setting off a flurry of innovation. Electric guitars were born!
āAt the time it was positively futuristic, with its lack of f-holes and way-cool art deco design on the pickup.ā
By this time, Memphis Minnie was a bona fide star. She recorded for Columbia, Vocalion, and Decca Records. Her song āBumble Bee,ā featuring her driving guitar technique, became hugely popular and earned her a new nickname: the Queen of Country Blues. She was officially royalty, and her subjects needed to hear her game-changing playing. This is where she crossed paths with our old pals over at National.
National and other companies began adding pickups to so-called Spanish guitars, which they naturally called āElectric Spanish.ā (This term was famously abbreviated ES by the Gibson Guitar Corporation and used as a prefix on a wide variety of models.) In 1935, National made its first Electric Spanish guitar, renamed the New Yorker three years later. By todayās standards, itās modestly appointed. At the time it was positively futuristic, with its lack of f-holes and way-cool art deco design on the pickup.
Thereās buckle rash and the finish on the back of the neck is rubbed clean off in spots, but that just goes to show how well-loved this guitar has been.
Memphis Minnie had finally found an axe fit for a Queen. She was among the first blues guitarists to go electric, and the New Yorker fueled her already-upward trajectory. She recorded over 200 songs in her 25-year career, cementing her and the National New Yorkerās place in musical history.
Our National New Yorker was made in 1939 and shows perfect play wear as far as weāre concerned. Sure, thereās buckle rash and the finish on the back of the neck is rubbed clean off in spots, but structurally, this guitar is in great shape. Itās easy to imagine this guitar was lovingly wiped down each time it was put back in the case.
Thereās magic in this guitar, yāall. Every time we pick it up, we can feel Memphis Minnieās spirit enter the room. This guitar sounds fearless. Itās a survivor. This is a guitar that could inspire you to run away and join the circus, transcend genre and gender, and leave your own mark on music history. As a guitar store, watching guitars pass from musician to musician gives us a beautiful physical reminder of how history moves through generations. We canāt wait to see who joins this guitarās remarkable legacy.
