Guitar FX (effects) refer to the wide range of pedals and processors that shape and manipulate a guitar’s signal to create different sounds. From classic distortion and overdrive to reverb, delay, modulation, and pitch-shifting, effects are at the heart of a guitarist’s creative toolkit. Whether analogue or digital, stompbox or multi-effects unit, Guitar FX allow players to express mood, texture, and dynamics in unique ways. Used thoughtfully, they can transform a simple riff into something atmospheric, aggressive, or entirely otherworldly.
A pedal is a compact device that guitarists use to alter their instrument’s sound by shaping effects such as distortion, delay, reverb, and modulation. Typically housed in a rugged enclosure and controlled by footswitches, pedals are designed to be placed on the floor for hands-free operation during playing. They can be analogue or digital, true bypass or buffered, and come in countless varieties to suit different styles and preferences. Pedals are essential tools for creating signature tones and adding colour and texture to a guitarist’s sound.
A guitar phaser is an electronic effect used to alter the sound of a guitar by creating a series of peaks and troughs in the frequency spectrum of the audio signal. This effect is achieved through a process called phase shifting, where the audio signal is split into two paths. One path remains unchanged, while the other is subjected to an all-pass filter that shifts its phase. When these two signals are recombined, they interfere with each other, creating the characteristic swooshing or swirling sound associated with phasers. This effect can add a sense of movement and depth to the guitar’s tone, making it a popular choice for both rhythm and lead playing.
Phasers often come with controls that allow the guitarist to manipulate various parameters of the effect. Common controls include the rate or speed of the phase shifting, which determines how quickly the peaks and troughs move through the frequency spectrum. Another typical control is the depth, which adjusts the intensity of the effect by varying the extent of the phase shift. Some phasers also offer resonance or feedback controls, which emphasize certain frequencies and can create more pronounced, dramatic effects. These adjustable parameters make the phaser a versatile tool, capable of producing subtle modulation to extreme, spacey sounds.
The phaser effect has a rich history in music, with notable usage across different genres. In the 1970s, phasers became particularly popular in rock and funk music, with bands like Pink Floyd and The Rolling Stones using them to create psychedelic and immersive soundscapes. Songs like “Breathe” by Pink Floyd and “Shattered” by The Rolling Stones showcase the distinct, swirling sound of the phaser. Over the years, phasers have continued to evolve, with modern digital models offering more precise control and additional features. Despite technological advancements, the core appeal of the phaser remains its ability to transform a guitar’s tone, adding a dynamic, textured quality that can enhance any musical piece.

JHS Pedals was founded by Joshua Heath Scott in Jackson, Mississippi. He began by repairing and modifying his pedals and then sold modified pedals at the local guitar shop before designing his own. Among his early models were the Morning Glory overdrive and the Pulp ‘N’ Peel compressor. In 2009 Scott moved the company to Kansas City, Missouri, eventually expanding to 10 employees.JHS released the Panther analogue delay in 2011 and the SuperBolt overdrive and Prestige booster/buffer/enhancer in 2012.
JHS manufactures and sells pedals with a variety of effects, including the Morning Glory V4, the Muffuletta, the 3 Series, the Pulp’N’Peel V4, the Andy Timmons AT+, the Paul Gilbert PG-14, the Legends of Fuzz series, the Unicorn Univibe, the Lucky Cat, the Double Barrel V4, the 1966 Series and the Colour Box preamp.
