Who would have thought that what started out as an above average blues band would become the prototype for heavy metal as we know it. From the opening sounds of a rainstorm to a bell that’s tolled for a thousand lives to the perfect use of the Devil’s Interval, Black Sabbath had, perhaps inadvertently, created something coherent and unique that immediately registered and resonated with listeners upon first exposure.
So rare is that occurrence that when critics started complaining but fans started following, the band knew to continue in the direction they had started. And we are all glad they did. As album after album of instant classics continued to fill the shelves, many guitar players started to wonder how Tony Iommi was getting such a heavy sound. And so our journey begins…
What we do know is that Iommi had a modified Rangemaster, one of the first treble boosters. Based on dropping the needle and some experimentation, it’s unlikely that Iommi got that kind of distortion from an amplifier and a treble booster. Our latest theory is that his Rangemaster was modified to include a fuzz unit. Most likely a two or three transistor model since the Rangemaster itself was a single transistor circuit.
What we have here is the classic VG402B Amplifier with the VG 4x12B 100W ’73 Cabinet and the EQ100 Treble Boost followed by the FZ101B Fuzz. This deep and heavy tone is amazing and we think you’re going to instantly hear those Black Sabbath classics when playing. Paired with an SG, you can’t get any closer. Enjoy!
Crank it up, this tone is heavy. Designed to imitate modifications done to Tony Iommi’s treble booster, we think we’ve found something special. But you be the judge. Use the fuzz to capture the dark sounds of Master of Reality or disengage and crank the amp for something brighter, similar to their self-titled debut.

Depending on your punk rock ethics, you may or may not have a lot to thank Mike Wallace for. Without question, his application of slick dance music production techniques to a new generation of punk willing to admit that they liked the Beatles helped define the sound of an era. Call it what you will, the music was infectious. Like songs you learned when you were a kid—they were easy to remember, enjoyable to sing along with, and aggressive and catchy as hell.
But Wallace was typically employed only as a mix engineer. He would get involved with projects after most of the material had already been recorded. In order to have such great material to work with, the raw energy in the studio still needed to be there. With Nirvana’s second album—their first on a major label—Wallace would create a blueprint for many bands to follow but first, the band needed to record an album. Enter Butch Vig. Having previously worked with Nirvana on some demos, he would become the vehicle through which the band would successfully get onto tape their pop infused ideas. Famously using John Lennon to coerce more takes, Vig knew exactly how to interact with underground artists.
Listening to the unmixed stems, it’s clear this album was meant to be raucous, heavy, and in your face. With AmpStamp, let’s take look at capturing that raw energy and giving it some slick studio production (or not, if you prefer). Here’s what we know:
- Kurdt Cobain’s amp had broken at an earlier gig and the band used the money they had to purchase a Mesa Boogie Studio .22 preamp and a power amp
- When the band checked in to Sound City studios, Kurt brought the Mesa Boogie with him. During recording he would also employ a Fender Bassman and some pedals but as Vig states, “Kurt Cobain, for the most part, used a Mesa Boogie amp”<sup>1</sup>
- Based on live appearances, a modern Marshall 4×12 was used
Careful! This one is hot! You may want to engage the Squelch control (noise gate). Though we know Kurdt used a distortion pedal to switch between clean and distorted tones, we think you’ll hear similarities using the high gain channel on this amplifier, it definitely packs a punch better than any pedal. Change the Color to get different left and right channel takes, and voilà—never mind.

Though not a Bassman, we think you’ll agree this sound is instant Grunge. With a thick quality unlike any modern amp, this was the secret ingredient to some of the moodier tracks on Nevermind. The tone is much darker so we’ve adjusted the Color for more brightness, but let your ears adjust to it, it’ll sit perfectly in a final mix.
