The organic sound of a breaking-up tube amplifier has been the gold standard for saturated and distorted tones ever since musicians began intentionally distorting their signals. The gentle natural compression and rich blend of even and odd harmonics produced by analog tube circuits make any affected signal feel more powerful, punchy, and alive.

Unlike solid-state transistors and fuzz circuits, which only produce odd harmonics and limit the incoming signal in an unnatural and unresponsive way, Redoptor responds fluidly and dynamically to changes in the volume of the incoming audio, like a real tube amplifier. This means that louder sounds saturate with more crunch and delicious harmonics, while softer sounds that naturally decay gradually clean up. This creates a sonically pleasing distortion.

Exact circuit emulation

In addition to its pinpoint modeling of hot pushed vacuum tubes for creamy and glorious distortion, Redoptor includes several features that allow it to accurately mimic the behavior of a complex analog circuit with all its interactive and complementary components.

Redoptor's adjustable tube bias parameter creates a subtle amplification of even harmonics and gentle transient reshaping in the signal. Each individual element of the plugin's signal chain has been designed similarly to capture the subtleties and dynamics of high-quality analog tube distortion.

Fully adjustable preamp

Redoptor expands the classic tube guitar amplifier circuit design by offering full control over the preamp's frequency range. The cutoff point for high and low tones can be set before the signal is amplified and distorted, allowing for incredible versatility in sound shaping, from lo-fi to full spectrum.

Parametric EQ

While many typical amplifiers and emulations rely on a fixed graphic EQ that offers limited control, Redoptor features a powerful parametric EQ with independent gain and 4-band frequency control.

Independent stereo channel processing

Although based on the mono signal paths of vintage guitar amplifiers, Redoptor is a fully functional stereo tube distortion with an independent path for each channel in the stereo signal. This allows completely different harmonics and distortions to be added to each side. Therefore, synthesizer sounds, for example, can benefit from improved definition and a stereo image in addition to the analog feel offered by the tube distortion emulation.

Dynamics under control

A built-in pre-gain compressor module and a master output limiter provide even more freedom to sculpt the perfect saturated sound. These two elements are essential in the studio for a creative gain staging. The preliminary compressor adds punch and controls the dynamic range of your signal before it reaches the highly responsive distortion stage. The master output limiter tames unruly peaks and polishes your signal as it leaves the plugin.

Unique character

Redoptor perfectly emulates the behavior of classic tube guitar amplifier circuits, allowing it to sound as good as its real-world analog ancestors.

Guitarists working in the digital realm will feel right at home with Redoptor. Those who have played with an excellent high-gain tube amplifier will immediately find the plugin's warmth, crunch, responsiveness, and singing harmonics familiar.

Producers and electronic musicians will also find Redoptor indispensable for the high-quality distortion, rich harmonics, and attitude it brings to their sounds.

Use it to re-amplify guitar parts, fatten up drum loops, sweeten arpeggiated synthesizers, reinforce bass lines, or warm up any sterile audio, and you will feel the difference of its warm, rich, and truly unique character that it brings to your music.
