NostalgiTone PowerStage

Description

The PowerStage is one of the most exciting circuits developed for NostalgiTone, combining a remarkably wide range of gain with the dynamic response, power, and control of a pushed amplifier.

True to its name, the PowerStage is designed to recreate the feel of an amplifier being pushed hard. Its exceptionally wide gain range takes you from a strong, open boost to thick, harmonically saturated overdrive, while allowing the character of your guitar and amplifier to remain intact. The gain responds directly to your playing, staying relatively clean with a lighter touch and becoming progressively more aggressive as you dig in, giving chords and single notes a distinctly amp-like response.

An active, low-noise dual-band EQ gives you independent control over the bass and treble response, making it easy to shape the circuit around your particular guitar and amplifier. The PowerStage can be used to push a clean amplifier, add another gain stage to an already-driven rig, or provide its own complete overdrive voice. The result is a circuit with real punch, dynamic range, and harmonic complexity that responds to the player rather than simply imposing its own character on the signal.
