With the Blonde Sound recently dialed in using the VG204D Amplifier, we decided to explore if this was the “baby” used on all of the classic VH records with David Lee Roth, not a Marshall. We re-tested previous theories with the new amplifier and the results were stunning. Here’s the second installment, Blond Sound II: Over the Edge.
Cutting Edge Speakers
“The majority of it […] is everything just stacked up and blazin’ away.” – Eddie Van Halen1

In early tone tests, our ears picked out Celestion G12Ms with black magnet covers—blackbacks—as being crucial to the sound of the second album. These speakers were a variant designed by Celestion and shipped during the mid to late 70s, with Kurt Müller cones. While we assumed Van Halen II would be a fresh take on Eddie’s tone, we found this to be more of a continuation of what Ed and engineer Donn Landee were experimenting with on the first album.
We use the term experimenting here because that’s the best way to describe what we think was happening. Most guitarists working on a sound tend to stumble onto something they like, lock it in, and make sure things never deviate from that magic recipe. While recording, if settings get adjusted or mics get moved by accident, they may need to start all over again fiddling to find the right combination of things that sounded so good. With Eddie and Donn though, it seems like they were constantly changing the sound, song to song as well as album to album. There must have been a confidence that no matter what, they could make their experiments sound good on record. Maybe they were using their time in the studio to learn as well as record. If things are always done the same way, you’ll never know any better. It’s just amazing to think that for a band that was defining a paradigm shift for electric guitar, they would continue to charge forward, never looking back.
So Who Was Kurt Müller?
Dr. Kurt Müller was a German cone maker who founded DKM in Berlin in 1922, quite possibly the oldest surviving cone factory still running. In 1970, the company bought a UK firm called Pulsonic Ultrasonics Limited and folded it into a subsidiary, Kurt Mueller UK Ltd. The Pulsonic cones Celestion fitted through 1973 are the ones collectors still chase—the warm, forgiving paper behind a lot of classic-rock tone. Around late 1973 that supply ran out. The story usually told is that a fire at the Pulsonic factory destroyed the formula for those cones—the fire is more legend than documented fact, and the truth behind it has never been fully pinned down.
The switch wasn’t immediate. For a couple of years Celestion used their own in-house “RIC” cones, only starting around 1975 did Kurt Mueller become the standard supplier—right as the cream magnet covers gave way to black, the “Blackback” era. Mueller cones sound different: a tighter low end, harder midrange, and a brighter, sharper, more aggressive top. That’s the voice a lot of hard rock and early metal was built on. One caveat on the ribs, though—those pressed concentric corrugations stiffen the paper against flex, but they aren’t a Mueller signature. Transitional Pulsonic cones carry pronounced ribs too, which is exactly why players can mistake one for the other.2-5
Going Over the Edge
There’s an old forum post that’s often quoted stating that for Van Halen, Eddie used a load resistor, and wouldn’t return to this setup until Women and Children First. For Van Halen II, that implies that if the amps were cranked, they were running at full volume in the studio. While we’ll never really know, the record does seems to have more cabinet ambience, and ultimately a darker tone, or at least not as bright as the first record. Maybe after a year of touring, Eddie had gotten used to using his live setup of re-amping and wanted to push his speaker cabs harder than what was achieved on the first record. Essentially, the sound of the VG204D Amplifier with some speaker distortion.
For the Blonde Sound II presets, we added a small amount of Cabinet Drive to simulate Celestion speakers being pushed hard. It’s a subtle touch to an already cabinet-heavy tone, and it does bring a certain edge to the sound. Chords get chunkier with more bass, leads have a searing, blistering quality, and as Eddie said himself, “everything [was] just stackedup and blazin’ away.”
The canonical second iteration of the Blond Sound—a deep, edgy, cab-heavy tone. Perfect for tunes like “Light Up the Sky.”
A brighter take on the second album, specifically targeting the razorblade edge of “Somebody Get Me a Doctor.”
More bass in this tone, but still with edge. Try the distorted riffs from “Women in Love.”
A cross between the previous two presets, brighter but not as harsh, targeting the inimitable phrases from “Beautiful Girls.”
More Lore
There’s also a connection to Over the Edge with “Light Up the Sky.” The song wasn’t written for the film—it was one of Eddie’s first riffs after the debut album. Warner Bros. was financing the movie and wanted Van Halen to write a theme song. The band considered offering up “Light Up the Sky” for the job, but it never happened. Eddie’s recollection is characteristically offhand—Warner backing “some movie,” the band thinking about using the song, “but I don’t think so. […] it ain’t gonna win no Academy Award or nothin’.”6
In the end the film went another way, licensing “You Really Got Me,” Van Halen’s Kinks cover off the first record and the only VH track on the Over the Edge soundtrack.
