{"product_id":"jhs-pedals-3-series-harmonic-trem-370160","title":"3 Series Harmonic Trem","description":"\u003ch3\u003eA \"Fender-style\" tremolo: the legacy of the 1960s Harmonic Tremolo\u003c\/h3\u003e\u003cp\u003eThe \"Harmonic Tremolo\" was born in the early 1960s in certain Fender amps (such as the Bandmaster and Vibrasonic). Although its name is historically misleading (it is indeed a volume effect, not a pitch vibrato), its sound is unique: the signal is split into bass and treble, then the effect alternates between these frequency zones, creating a more complex pulse than a classic tremolo. With the \u003cstrong\u003e3 Series Harmonic Trem\u003c\/strong\u003e, JHS brings this retro sensation up to date in a portable format, without needing to carry a vintage amp.\u003c\/p\u003e\u003ch3\u003eFor which guitarists and situations?\u003c\/h3\u003e\u003cp\u003eThis pedal is suitable both for musicians discovering effects and for experienced guitarists who want a musical, effective tremolo that is quick to dial in. The standard tremolo mode is perfect for surf, indie, country, or vintage rock rhythms, while the harmonic trem mode adds a more \"liquid\" and floating dimension, ideal for modern blues, pop, post-rock, and ambient settings. In the studio, it fits easily into a clean or slightly overdriven recording chain\u0026#59; live, its direct controls allow adjusting speed and intensity between songs without hassle.\u003c\/p\u003e\u003ch3\u003eSimple controls, wide palette: from subtle to hypnotic\u003c\/h3\u003e\u003cp\u003eThe philosophy of the 3 Series is clear: focus on essentials without sacrificing musicality. \u003cstrong\u003eVolume\u003c\/strong\u003e adjusts the output level (useful to compensate for perceived drop when modulation is deep, or to push the next stage). \u003cstrong\u003eRate\u003c\/strong\u003e sets the speed, from slow, wide movements to fast pulses. \u003cstrong\u003eDepth\u003c\/strong\u003e controls the effect intensity: a light shimmer on a sustained chord or a pronounced tremolo for rhythmic patterns. Finally, the \u003cstrong\u003eType\u003c\/strong\u003e toggle changes the modulation character: up for a standard amp-style tremolo, down for JHS's version of the \u003cstrong\u003eharmonic tremolo\u003c\/strong\u003e, richer and more textured.\u003c\/p\u003e\u003ch3\u003eThe sound\u003c\/h3\u003e\u003cp\u003eIn standard tremolo, the 3 Series Harmonic Trem offers a clear, organic, and steady volume modulation that respects right-hand playing and instrument dynamics. The harmonic trem mode adds a more \"3D\" sensation: the pulse seems to move across the spectrum with a smoother motion, sometimes close to a swirl impression, particularly flattering on clean tones, open chords, and arpeggios. With slight overdrive upstream, the effect gains character and thickness while remaining clear\u0026#59; with reverb or delay after the pedal, it creates cinematic textures and hypnotic soundscapes.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr)
