What’s a Pedal Tone?
A pedal tone or pedal point is static note—usually in the bass register—against which higher notes and/or chords are sounded. Ex. 1 is reminiscent of a rhythm guitar lick favored by early metal pioneers like Ozzy Osbourne guitarist Randy Rhoads, or Glenn Tipton and K.K Downing of Judas Priest. It features two-note dyads (also called double-stops) articulated against a pedal tone on the open 5th string in a jagged syncopated rhythm. Palm mute the open string and articulate the chord stabs with a short aggressive picking-hand motion.

Riffin’ With the Devil
Western music is based on a division of the octave into 12 equal half-steps, and on guitar a half-step is simply one fret’s distance. One of the most sinister-sounding intervals is the tritone, which is named because you have three whole-steps between the notes. In fact, it has often been called “The Devil’s Interval.” Guitarists like Black Sabbath’s Tony Iommi and Metallica’s James Hetfield have both used its jarring edge to great effect, often sounding a Bb5 power chord against an open 6th string pedal tone for maximum angst. Play through Ex. 2 to get a taste of the ominous-sounding tri-tone interval and remember to keep a slight palm-mute on the pedaled 6th string.

16th-Note Shred Secrets
As metal progressed into the new millennium, it branched off into various subgenres, many of which relied on a fusillade of rapid-fire 16th-note riffs played at breakneck tempos. Mastering the metric methods of bands like Slipknot, Gojira, and Lamb of God may seem daunting. The trick is to realize that there are only a finite number of ways to subdivide a beat and, once learned, these individual one-beat stems can be strung together in different combinations to create more complex patterns. Ex. 3 shows four common 16th-note rhythms. Play the first using a steady alternate picking-hand motion. For the second, third, and fourth patterns, continue the alternate picking-hand motion but “ghost” the missing stroke by simply not hitting the string. It’s imperative that your picking-hand never stops an alternating motion. This will help you navigate complex rhythms with both speed and accuracy. Once mastered, the four stem-rhythms can be connected together consecutively to create driving single-note riffs like the one in Ex. 4.

Flirtin’ With Invertin’
The root-fifth power chord voicing is the most common form of harmonic currency in the metal kingdom. One cool-sounding derivative of this formula is to switch the positions of (aka “invert”) the root and the fifth by playing the root above the fifth. This grip can be sounded by simply barring across any fret on the two lowest strings or—for a fuller sound—adding those same two notes up an octave by also barring the D and G strings two frets higher. Check out the C#5/G# power chord in Ex. 5. Once learned, this grip can be tied in with 16th-note rhythms and a pedaled low E string as shown in Ex. 6.

Drop to the Top
One lasting sonic innovation that became ubiquitous in metal was when King’s X started to crank out incredible drop-D riffs. To be fair, other guitarists had experimented with this before, but it was King’s X who first worked out a harmonic vocabulary around the one-finger root-fifth-octave power chords that are easily facilitated by the drop tuning like the F5 shown in Ex. 7.
Ex. 7
Now power chords could be phrased with the same expression and fluidity as single notes. Ex. 8 ably demonstrates how a one-finger-barre voicing makes full-chord slides, hammer-ons, and pull-offs easy to facilitate.
Ex. 8
By the mid ’90s, myriad variations of lowered tunings had become extremely commonplace in the metal universe. Beginning guitarists are sometimes flummoxed by these alterations, but the overwhelming majority of the time they are just detuned versions of both standard and drop-D tunings, meaning everything you play in them will be fingered the same way, it will just be at a lower pitch. Some of the most common lowered tunings in metal are standard down a half-step, aka “Eb” (Eb–Ab–Db–Gb–Bb–Eb), standard down a whole-step, also called “D standard” (D–G–C–F–A–D) and drop-D down a whole-step (C–G–C–F–A–D), which is sometimes referred to as drop-C. If you’re a little hesitant about retuning your guitar, keep in mind that you’ve already learned to tune it to standard.
Learning to switch back and forth to a different tuning will be just as easy (if not easier) than when you first learned to tune. Try retuning your guitar to these then revisit some of the previous examples using the exact same fingerings, and see how the lower register affects the sound.
Octivate Your Device
Another cool intervallic device commonly used in hard rock and metal riffs is the octave shape shown in Ex. 9. It is most easily fingered by removing the middle note of a root-fifth-octave barre chord. You’ll want to use your first finger to fret a note on the fifth string while curving it to make enough contact with the fourth string that it mutes that string completely.
Ex. 9
Octaves are great for sliding melodically up and down the neck and—as demonstrated in Ex. 10—can be sounded in unison against pedal tones, or broken up into individual notes creating cool intervallic leaps. In the latter case remember to keep the octave hand shape constant.
Ex. 10
Now that you’ve got a basic handle of some of the most common rhythm guitar techniques you can listen to how they are employed by the great artists of the genre and use this as a jumping off point for your own songs!

Hand-crafted in Petaluma, California, this amp features upgrades while maintaining the original's legendary tone.
The Mesa/Boogie Dual Rectifier Solo Head’s arrival in 1992 was a watershed moment for alternative rock and metal that changed everything; heavy music would never sound the same again, and the Dual Rectifier’s crushing, harmonically rich tone became the most sought-after guitar sound of the era. With a feel as empowering as its sound, the Rectifiers provided an ease of playing that supported and elevated proficiency and was inspirational, rewarding, and addictive.
Its sound and impact on the generation that used it to define what rock music would become were as sweeping as they have been lasting. And it remains arguably the most modeled in today’s digital amp landscape. Now, the 90s Dual Rectifier is back with a vengeance, built in Petaluma, California, by the same artisans who made the originals the most desirable high-gain guitar amplifier of all time.

Featuring Bluetooth input, XLR inputs, and advanced amplifier platform, the KC12 is designed to offer exceptional sound quality and versatility for a wide range of applications.
The KC12 is a first-of-its-kind, 3-way, 3000-watt active loudspeaker system encompassing the visual aesthetic of a column loudspeaker while surpassing the acoustic performance of conventional designs. Simple and easy to deploy, the elegant KC12, available in black and white, is ideal for a wide range of customers and applications from solo entertainers, musicians and bands, mobile entertainers and DJs to corporate AV, event production, and static installations.
Column-style portable loudspeaker systems are most often put into service due to their unobtrusive form factor. However, typical designs lack clarity and definition, particularly when pushed to high output levels, forcing the user into a form-over-function compromise. Solving this common dilemma, the KC12 cleverly utilizes a 3-way design featuring QSC’s patented LEAF™ waveguide (first introduced in L Class Active Line Array Loudspeakers) combined with a true 1-inch compression driver, two 4-inch midrange drivers, and a high output 12-inch subwoofer, while still maintaining the desired, elegant appearance of a “column” system. The KC12 produces an outstanding full-range horizontal coverage of 145 degrees and 35 degrees of audience-directed vertical coverage with clean and natural sound at all output levels.
The system features three inputs: a Bluetooth ® input combined with a 3.5 mm TRS stereo input, as well as two combo XLR inputs (Mic/Line/Hi-Z and Mic/Line/+48 V), with independent, assignableFactory Presets for each XLR input, making it ideal for small events where two microphones are needed for different uses. The rear panel incorporates a multi-function digital display, offering control and selection of several loudspeaker functions, including Global Parametric EQ, Subwoofer level, Presets and Scenes, Bluetooth configuration, Delay (maximum of 200 ms), or Reverb. Bluetooth functionality also provides True Wireless Stereo (TWS), which ensures low latency pairing between the music source and both left and right loudspeakers simultaneously.
Additionally, the KC12 can be deployed with or without its lower column pole, making the system ideally suited for utilization on a floor, riser or raised stage. The system is backed by a 6-year Extended Warranty (with product registration).
“The KC12 exquisitely resolves the form-over-function compromise that has frustrated users of this category of products since they made their market introduction over 20 years ago,” states David Fuller, VP of Product Development, QSC Audio. “With the benefit of time, experience, extensive customer research, and cutting-edge innovation, our talented design team has truly created something very different from the status quo – not simply a differentiated product, but an overall better solution for the customer.”
The feature set and performance characteristics of the KC12 are complemented by a new, advanced amplifier platform, first incorporated into the L Class LS118 subwoofer released this past October. Fuller adds, “Among the platform’s key attributes are layers of real-time telemetry and protection to ensure uninterrupted performance day after day, which is a foundational QSC brand attribute.”
“Just like our first K Series reset the bar for powered loudspeakers, elevating customers’ expectations for performance, quality, reliability, usability, and professional appearance, the K Column offers a compelling, new approach to a familiar category and is destined to redefine the whole notion of what a ‘column’ is for users of portable PA products,” states Ray van Straten, VPBrand, Marketing & amp; Training, QSC Audio. “The product is simply stunning in its sleek and elegant appearance, but with the marketing tagline, ‘Just Listen’, we’re confident that once again, QSC sound quality will ultimately be the reason customers will quickly embrace the K Column as the next ‘New Standard’ in its category.”
The QSC KC12 K Column carries a MAP price of $1,999.

This pedal is designed to offer both unique distortion qualities and a tonal palette of sonic possibilities.
At the heart of the Harvezi Hazze pedal is a waveshaper designed around a unijunction transistor - a relic from the early days of the semiconductor industry unearthed from the e-waste bins of flea markets in Tbilisi, Georgia, the Eastern European country's largest city.
The unijunction transistor offers unique properties allowing one simple component to replace a number of very complex devices. Therefore. depending on the operating mode, users can access a distortion, a limiter, a waveshaper and a generator - with smooth transitions among each of these.
The name "Harvezi Hazze" translates from Georgian as "a fault on the transmission line" or "signal jamming", and both the semantic and phonetic nature of these translations imply what users can expect: an impediment to the input signal, which can range from pleasant harmonic distortions to complete obliteration. The signal chain of Harvezi Hazze consists of an optical compressor with fixed parameters; a dual-mode distorting amplifier with either softer or harsher clipping; a waveshaper built around a unijunction transistor; and a tone stack section designed to tame these sonic building blocks.
Signal flow and controls
Following the input, the signal goes to the Compressor, Distorting Amplifier, Waveshaper, and then to the Tone Stack and output stages. Harvezi Hazze features six control knobs, a three-way switch and a footswitch.
- Gain Control: This controls the output amplitude of the signal in the distorting amplifier section. Depending on the position of the switch, the distortion introduced by this section is soft (with the switch in the left position) or more aggressive with an abundance of high harmonics (with the switch in the middle position).
- Spoil and Spread: This knob controls the operation of the unijunction transistor (waveshaper section). Spoil sets the point on the amplitude axis at which the wave will fold, and Spread sets the amplitude of the folding. The higher the Spread value, the more severe the distortion will be, while Spoil will change the timbre and response threshold. By adjusting Spoil, users can achieve various gating and cutoff effects; at low Spread values, distortion sounds are mixed into the clean sound.
- Tone: This knob adjusts the brightness of the sound. With higher values, higher harmonics become present in the signal.
- Three-way switch. This feature regulates either the distortion mode in the amplifier section (left and center positions), or turns on the total feedback mode (right position) when the values of all knobs begin to influence each other. In this position, effects occur such as resonance at certain frequencies and self-oscillation.
- Level knob: This controls the output volume of the signal.
- Footswitch: This routes the signal through the effect circuitry or from input to output directly (true bypass).
The array of switches on the side of the unit provides even further tonal options; the lower position of the switch enables the specific function:
- Tone Stack: Routes the signal through the tone stack section (Tone knob).
- Bass Boost: Enhances bass frequencies.
- Tone Mode: Changes the behavior of the Tone knob (tilt or lowpass).
- Notch Freq: Changes the central frequency of the filter.
- High Cut: Attenuates high frequencies.
- Compressor: Routes the signal through the compressor.
