Harmonic Booster: Clean Bass Preamp

The Harmonic Booster was our first design ever.

In our quest to design the perfect bass distortion, first, we had 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 then when testing the first few gain and filter stages of what would later become the core of our overdrive technology that we realized 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.

We have picked up a few tricks over the past decade, which translates into several improvements over the original design: aside from comprehensive EQ for additional flexibility, noise performance and headroom are 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.

Along with this, we have a 3-band active equalizer with our staple bass and treble knobs, but for the first time in Darkglass history, featuring a semi-parametric mid control!

And although it is designed to be the perfect complement to our distortion circuits, its incredible flexibility and portability make it the perfect one-stop solution for gigging musicians in search of a precise, and harmonically rich clean preamplifier.

I like that a lot, but probably I'll be waiting for some kind of deluxe or ultra version of this design

[marcelocortesrivera]

directo a la nostalgia el comienzo del video, sobre todo para los que seguimos tu trabajo desde tus inicios!

[YandtheB]

have one. my bass is a ibanez gsr206. this pedal is fantastic. the clean boost is no joke. the low B is crisp and articulate. the highs ring through no distortion. just well done. i also use my guitar through it as well. nice and crisp. bueno. the amount of range or headroom on the bass/mid/treble is more than you think possible.

I was interested in buying this, based on the name, but after the video - I'll keep looking

My idea of a holy-grail multi-pedal would be this preamp combined with the hyperluminal compressor and the drive section from the alpha omega but with the crossover clean lows from the Microtubes X, all with a switchable cab sim and xlr out.

[OlandoMcCall]

I guess a video showing how it sounds was too much....

[darthprawn]

Patrick, where's our review at bro? ;)

[AsHat]

is this sound from only this pedal or did they chain it with something else to get that dist.

[mindbodylightsound]

Really want a stereo di box that has this on one channel and AO drive on the other + compressor.

[TheBassdude]

How does this compare with the Microtubes X Ultra that I just purchased?

[Elderscrollsgamer]

The bassist looks a little like Dave Hollingworth

My guy tryna look at me sexy while doing sloppy tapping
Consider me turned off lil doo

This is a clean🙄 but it sounds with a little distortion... Tail...
