Digitech RPx400 Amplifier Modeling & FX Presets Library

Achieve flexible guitar tone with this Presets Library for the DigiTech RPx400, created for the USB-equipped floor processor introduced in 2004.
 
This collection delivers articulate cleans, gritty edge-of-breakup crunch, tight modern rhythm gain, and smooth sustaining leads with a focused early digital character. Amp models respond quickly, offering fast transients, controlled low end, and balanced mids that sit well in dense mixes. Effects remain musical and precise, adding space, movement, and depth without masking core tone. Gain staging and EQ are carefully balanced for consistency across different guitars and pickup outputs.
 
All presets are fully import ready, clearly organized, and optimized for immediate use. Built around the RPx400 processing engine, this library provides clarity, versatility, and dependable tone for recording, practice.
