The Ultimate Acid Box

This is a carefully curated, pristine Eurorack acid machine built for hands-on sequencing, raw character, and immediate pumping acid.

At the heart of the system is the legendary Intellijel Metropolis, one of the most playable and musical Eurorack sequencers ever made. It delivers instant acid lines, evolving patterns, and performance-ready control without menu diving. Paired with the Erica Synths Bassline, you get aggressive filter movement, punchy bass and dirty techno sequences that cuts straight through a mix.

Supporting this core are precisely chosen utilities and voices that elevate the system from a single sound to a full instrument:

• Intellijel 1U tools for noise, modulation, mixing, and effects that keep everything tight, musical, and ergonomic
• Percussive firepower from Erica Synths Drum2 for rhythm and accents
• Character drive and grit from Erica Synths Pico Drive. Keep it subtle for extra weight and harmonics, or push it until the Bassline starts screaming.
• Polyrhythmic variation via 2hp Euclid, creating evolving pulses, accents and polyrhythmic patterns
• Clean and flexible summing from Befaco Stmix

This is a box you can switch on and start performing with in minutes, whether you are into classic acid techno, electro, or modern modular live sets. It can be hypnotic and minimal one minute, filthy and completely unhinged the next. Acid techno, electro, warehouse grooves, experimental sequences, live jams. Just patch, twist and follow wherever it takes you.

The rack and modules are in pristine condition, treated as a focused, professional acid performance system that would cost EUR 2.200 to assemble new today, ready to inspire its next owner from the first patch cable.
