Darkglass Electronics are renowned for their high-gain distortion and fuzz stompboxes. However, before dabbling with the innovative Microtubes technology that is used in many of their current products, Darkglass launched the Harmonic Booster – their first ever pedal design. Heavily sought after, the Harmonic Booster is finally back and better than ever before!

Just like the original, the Darkglass Harmonic Booster 2.0 is primarily a clean preamp that offers plenty of tone-shaping potential with its 'Bass' and 'Treble' controls, and most notably – a sweepable parametric mid-range. Letting you find the sweet-spot, this flexible active EQ section as a whole offers mixing desk-level precision, especially in conjunction with the 'Character' control that allows you to determine how much of the EQ circuitry affects your core sound.

The 'Boost' knob delivers up to 20 dB cut/boost, but apart from simply affecting volume, the boost function also introduces extra harmonics to create a richer sound; akin to an exciter. The Darkglass Electronics Harmonic Booster 2.0 can therefore serve as an "always on" pedal that'll guarantee excellent tone no matter what you plug it into!

Here's what Darkglass Electronics says about the Harmonic Booster 2.0:

The original Harmonic Booster was Darkglass Electronics’ first ever pedal design. Now with the Harmonic Booster 2.0 the mythical product that started it all is back, but with major improvements over the original.

In the quest to design the perfect bass distortion, you first have to master the control of harmonics and filtering, which are crucial to sculpting the character and texture of a distortion circuit at will. It was when testing the first few gain and filter stages of what would later become the core of Darkglass’ overdrive technology, that it was realised that the harmonic excitation circuitry could yield amazing results on a clean signal at lower gain levels!

The result was a clean preamplifier that enhances attack and presence, while sculpting the mids for a very percussive and aggressive character and now rare examples of this early design are highly sought after. Darkglass Electronics has picked up a few tricks over the past decade, which translates into several improvements over the original design.

Aside from a new comprehensive EQ section for additional flexibility, noise performance and headroom are all vastly improved in V2.0. The unique tone-shaping engine can be controlled with the Character knob, which at minimum leaves your signal completely flat, providing absolute control from subtle to extreme enhancement. In addition, the new 3-band active equalizer, with bass and treble knobs, also features a semi-parametric mid control – a first for Darkglass!

Although Harmonic Booster 2.0 is designed to be the perfect complement to the line-up of Darkglass distortion circuits, its incredible flexibility and portability makes it the perfect one-stop solution for gigging musicians in search of a precise, yet harmonically rich clean preamplifier.

Features

More info about this Product

Guitar Pedals

Guitar pedals are compact effects units that shape and enhance a guitar’s sound, sitting between the instrument and the amplifier. They include gain pedals like overdrive and distortion, modulation effects such as chorus and tremolo, time-based effects like delay and reverb, and essential utilities including tuners, compressors and loopers. Understanding basic things such as pedal type, signal order, power requirements and intended use helps players choose pedals that suit their style, setup and playing environment.

Bass

Bass gear is all about laying the foundation of the music, providing depth, groove and connection between rhythm and harmony. From bass guitars and amplifiers to pedals and accessories designed specifically for low frequencies, everything here is built to deliver clarity, punch and control. Whether you are holding down a steady rhythm or shaping a more melodic bass voice, the right bass equipment helps you stay locked in and felt as much as heard.

Boost

Boost pedals give your signal that extra push — perfect for cutting through the mix or driving your amp into sweet natural overdrive. Whether you want a clean volume lift for solos or a touch of grit to wake up your tone, a good boost adds clarity, punch, and presence without changing your core sound. Simple, powerful, and essential on any board, a boost pedal can turn a good tone into a great one with just one stomp.

Clean

Pedal

Pedals are the tools that let you shape, colour and transform your sound, from subtle tone enhancement to bold, creative effects. Whether you are adding grit, space, movement or control, a pedal becomes part of your playing rather than just an add-on. Exploring different pedals is about discovering what responds to your touch and helps your sound feel more like your own.

preamp

A preamp is a stage in the signal chain that boosts the guitar’s signal and shapes its core tone before it reaches the power amp or recording interface. Preamp pedals and units can add gain, EQ, and character, helping define clarity, warmth, and drive while forming the foundation of a player’s overall sound.
