Crazy Tube Circuits

Crazy Tube Circuits at Kirstein

Crazy Tube Circuits develops effects pedals with a clear connection to classic amplifiers and historic effects circuits. Rather than focusing on a single type of effect, the brand covers various areas of the pedalboard. These include overdrive, distortion and fuzz as well as boost, compression, delay, reverb and modulation. A characteristic feature is the way its pedals take familiar sound concepts further with additional voicings, control options or multiple effect sections that can be combined.

Many models are therefore interesting when a pedal needs to offer more than a single fixed sound. Unobtanium, for example, combines an overdrive section with a D-style amp-in-a-box, while Crossfire pairs a Blackface-inspired amp section with a classic mid-hump overdrive concept.

Overdrive, distortion and fuzz for different amp characters

Dynamic drive pedals are a major focus for Crazy Tube Circuits, with individual models offering distinctly different tonal approaches. Falcon, for example, is inspired by the behaviour of Tweed and Brownface amplifier circuits and takes typical compression and sag characteristics into account alongside overdrive. Heatseeker, by contrast, uses an analogue JFET concept with three British-inspired amp voicings and combines its amp section with a separately switchable boost/enhance section.

For more powerful fuzz and distortion sounds, Motherload provides two independent analogue circuits inspired by classic Muff and RAT concepts. Its tone controls can be used separately or shared via the link function. When choosing a pedal, it is therefore worth considering whether it should deliver a particular amp character, push an existing amplifier or serve specifically as a distinctive fuzz or distortion.

Reverb, tremolo and delay for spacious sounds

Crazy Tube Circuits also takes different approaches to ambience and time-based effects. White Whale V2 combines analogue spring reverb with tremolo and uses a real spring reverb system. The reverb and tremolo sections can be controlled independently, and their order can be adjusted.

Mirage and Mirage JR add versatile reverb pedals to the range, while TIME is one of the options for echo sounds. The pedal offers adjustable delay time, repeats and tone as well as modulation and tempo control options. Multifunctional concepts such as Sidekick JR combine modulation, delay and reverb in one compact unit, making them suitable for pedalboards where several types of effects need to remain readily available.

Using modulation, boost and dynamics effectively

With Cyclone, Crazy Tube Circuits covers classic phaser sound worlds. The analogue pedal offers several voicings, allowing different variations of the phaser effect. Super Conductor takes a different approach: four analogue boost circuits, each with its own tonal character, are available in a single pedal. This allows an amplifier to be driven in different ways depending on the selected circuit or the signal to be shaped more precisely.

Which Crazy Tube Circuits pedal suits your setup?

When choosing a pedal, it helps to first define its role in your rig. For amp-in-a-box and drive sounds, models such as Falcon, Heatseeker, Crossfire or Unobtanium are potential options, while Motherload is more specifically focused on fuzz and distortion. White Whale V2 is aimed at guitarists looking to combine spring reverb and tremolo, while Cyclone expands the modulation section of a pedalboard. Sidekick JR is an option for players who want to combine several types of effects in one unit.

At Kirstein, Crazy Tube Circuits effects pedals come with a 3-year Kirstein warranty, and competent expert advice is available if you have questions about effect types, signal chains or how a pedal works with your amplifier.
