Bigger sound, smaller box! The Hulk is an update on our very popular Density Hulk subharmonic synth.
The controls have been streamlined to save space, as most people only used the 30hz and 60hz controls as "set and forget". They are still accessible, however, via internal trimpots. The default setting for both is max.

The max output volume has been increased.

An internal switch allows the footswitch to act as a "kill dry". This feature is for users who desire to run sub direct to FOH but don't want their uneffected signal to pass when the pedal is disengaged.
Unlike other updated sub pedals, we managed to keep the dedicated dry output on this model as well as offer a smaller footprint.

Use it to subtly fatten up your sound, or dial up extreme settings for a powerful barrage of all-out synth tones.

Der Blumes ist ein Overdrive, der auf dem Plumes-Schaltkreis basiert und ideal für Bassisten und alle, die gerne tiefe Töne spielen, geeignet ist. Es wurden die wichtigsten Merkmale und Eigenschaften des Plumes übernommen, aber die Schaltung mit dem doppelten Gain und einer tieferen Basswiedergabe modifiziert, um das gesamte Low End beizubehalten. Bei niedrigeren Gain-Einstellungen erhältst du den knackigen Ton, den du vom Original so liebst, aber sobald du den Gain-Regler über 12 Uhr stellst, hören die Ähnlichkeiten auf. 
Dieser rein analoge Tri-Mode-Overdrive mit Soft Clipping ist der Nachfolger des klassischen Screamer-Schaltkreises, hat aber eine ganz eigene Stimme. Und dank seiner +/- Stromversorgung nutzt er bipolaren Strom, was mehr Dynamik, Klarheit und den ganzen Headroom bietet, den man sich nur wünschen kann. Das Endergebnis ist ein dreidimensionaleres Klangbild mit zusätzlicher Klarheit, der einen guten Röhrenverstärker wirklich auf Touren bringt. 
Und ähnlich wie das Plumes bietet dieses Pedal drei verschiedene Clipping-Optionen für die gewünschten Low-End-Face-Melting-Bedürfnisse.

The Blumes is an overdrive based on the Plumes circuit that is ideal for bass players and all purveyors of low-end. While embodying the key characteristics and features of the Plumes, they went ahead and modified this circuit with double the gain and a deeper bass response to retain all the low end. At lower gain settings, you’ll get all of the crunchy tone you love about the original, but once you get above noon on the Gain control, that’s where the similarities stop. 
This all-analog tri-mode overdrive with soft clipping carries the torch of the classic screamer circuit but has a voice all its own. And thanks to its +/- power supply it utilizes bipolar power, which gives you more dynamics, clarity, and all the headroom you could ever desire. The end result is a more three-dimensional tone with added clarity that really pushes a nice tube amp over the edge. 
And much like the Plumes, this pedal offers three different clipping options for your desired low end face melting needs.

Brand new version of a modern classic. This pedal is essentially the one octave down circuit of the 80’s Boss Japanese Octaver but with the addition of filter (which effects the octave signal) and an improved clean/direct knob based on our clean boost.

At 12 o clock the filter switch is much like your standard Octave. Turn clockwise for more of a low mid bump, to cut through the mix and turn anti-clockwise to destroy the PA.

The greatest pieces of studio gear studio gear are the ones that add something special to the sound of an instrument, going beyond the job they were designed for and enhancing anything that passes through the circuit. One such piece is the UA 610 preamp, which was the inspiration for the DCX Bass. This retro console preamp is famous for adding vintage, analogue colour to a signal, as well as precise control of level and EQ. Push the level harder and you get rich, harmonic saturation of the kind that makes analogue hardware a must-have in any present-day studio.

The DCX Bass reimagines this classic preamp as a tone-shaper and drive pedal for bass guitar, with a wide range of clean and overdrive tones, EQ frequencies optimised for the instrument, and our Adaptive Circuitry providing a treble response that reacts to playing dynamics. It’s a signal-boosting, tone-enhancing pedal straight from the studio!

DOOM 2 is an original fuzz circuit that turns your input signal into something resembling the sawtooth wave of a vintage synthesizer. Unlike most fuzz-style circuits, DOOM 2 responds to your playing technique and retains note dynamics.
New for version 2 is the you’re / your switch. You’re is the classic DOOM sound - strong upper harmonics, a mid-focused sound, and octavia / ring modulator effects as you play up the neck. Your is a new mode that has a stronger fundamental, more low end and fewer harmonics. This mode sounds more like a traditional fuzz.

The Halcyon Gold Overdrive is an adaptive overdrive pedal featuring our proprietary Adaptive Circuitry. This unique design allows it to adapt its voicing in response to pick attack and volume changes, making it one of the most dynamic and interactive overdrives out there. While it is inspired by a certain rare and sought-after pedal, this is by no means a clone. We have gone to great lengths to recreate the exact characteristics of unobtainable vintage diodes and also built in some innovative features that go beyond the capabilities of the original.

This dual-mode octaver gives you harmonically rich sub octaves with the option to click on a second footswitch that will solo your sub octave sound.

Die Walrus Audio Julia ist ein komplett analoges Chorus/Vibrato-Pedal, das mit einigen Besonderheiten aufwarten kann. Obwohl es sich bei den beiden um alteingesessene Standard-Effektsounds handelt, versteht es der amerikanische Boutique-Hersteller, mit einigen Extras jenseits der Norm Interesse zu wecken.
So auch bei der Julia, bei der beispielsweise fließend mit einem Blend-Regler zwischen Chorus und Vibrato gewechselt werden kann. Dazu lässt ein Schalter die Wahl, den LFO zu Sinus- oder Dreieck-Wellenformen zu überreden. Was diese Funktionen klanglich bewirken, schauen wir uns im Folgenden an.

The Julia is a fully analog, feature-rich chorus/vibrato packed with a wide array of tonal landscapes begging to be explored. Updated for 2020, Julia now has top mounted jacks, soft switch bypassing and updated art from Adam Forster. 

Julia is able to produce mild smooth chorus, to seasick vibrato and everywhere in between. With controls like Lag, Dry-Chorus-Vibrato Blend, and selectable analog LFO wave shapes, you are able to dial in all types of classic and unique chorus/vibrato sounds; some settings giving a familiar feel while others are not found on traditional chorus pedals.

A special feature of the Julia is the Lag control. The Lag knob lets you set the center delay time that the LFO effect modulates from. From smooth and tight modulation at lower settings, to warbling detune at maximum, the Lag knob adds a new dimension to the traditional Chorus/Vibrato landscape.

Das Empress Effects Bass ParaEq ist ein hochwertiges analoges parametrisches Equalizer- und Boost-Pedal, das speziell für Bassisten entwickelt wurde, die präzise Klangkontrolle suchen. Es verfügt über drei vollständig einstellbare parametrische EQ-Bänder mit variabler Q und ermöglicht eine Anhebung oder Absenkung von ±15 dB. Das Pedal beinhaltet Hochpass-, Tiefpass-, Tiefen- und Höhen-Shelving-Filter, die umfassende Frequenzformungsmöglichkeiten bieten. Ein fußschaltbarer Boost bietet bis zu 30 dB sauberen Gain, und das Pedal arbeitet intern mit 27V für außergewöhnlichen Headroom. Weitere Funktionen sind ein wählbarer 10MΩ Hi-Z-Eingang für Piezo-Tonabnehmer und ein automatisch erkennender symmetrischer Ausgang, was es sowohl für Live- als auch Studioanwendungen geeignet macht.

The Empress Bass ParaEq is the only parametric EQ pedal on the market built from the ground up for bass. It gives players studio-grade tone shaping in a compact pedal format that is purpose-built for low-end instruments, not just adapted from guitar gear.

Following the success of our Bass Compressor—and after hearing from countless players who were already using the ParaEq MKII Deluxe on bass—we knew it was time to give bassists more than a “good enough” EQ. The Bass ParaEq delivers the same transparent, tone-sweetening power that made the Deluxe a favourite, but with frequency ranges, filters, and features tailored specifically for bass.

With a dynamic low shelf, bass-tuned EQ bands, a Hi-Z input for upright players, and an auto-detecting balanced output, it’s built to give bassists the control they’ve always deserved—on stage, in the studio, everywhere.

The Fredric Effects Demon Fuzz is a new take on a classic pedal. The late 70s EH Muff Fuzz was a great-sounding mid-gain fuzz with only a volume control to fiddle with. Originals are rare, fragile and expensive, so Fredric Effects have used the basic IC (integrated circuit) Muff Fuzz as the basis for the Demon Fuzz. We've upped the gain a touch, added a switch for selecting silicon clipping diodes for a crunchier distortion or germanium for a vintage correct sound.
