The D100PRE is a professional three-channel, all-tube guitar preamplifier — designed for players who demand the power, versatility, and feel of a boutique amplifier in a compact rack format.
Built as the natural evolution of the legendary Duality 100, it delivers the same unmistakable RedSeven tone: rich cleans, dynamic overdrive, and a powerful modern lead channel — all within a 2U rack unit.

Each of the three channels has its own personality:

• Clean Channel – a blend of ‘50s Fender sparkle and late-’60s British clarity, with crisp definition and dynamic headroom.

• Vintage Channel – the signature RedSeven sound: punchy, articulate, and harmonically rich, from crunchy rhythm to soaring rock leads.

• Modern Channel – tight, aggressive, and saturated, perfect for cutting-edge high-gain tones.

The D100PRE includes programmable tube-based boosts for gain, solo, and bright functions — letting you shape your tone and dynamics in real time, all controllable via MIDI CC and PC commands.
Its 100% analog tube audio path ensures warmth and depth, while digital memory allows up to 128 presets, making it a perfect hybrid of classic sound and modern control.

Handcrafted in Italy and equipped with audiophile-grade “Manta RV24” potentiometers, the D100PRE offers unmatched precision, durability, and tone consistency.
Whether on stage or in the studio, it’s the ultimate tone weapon — compact, reliable, and undeniably RedSeven.
