Two Unique Takes on the Greenback Sound–Yours to Explore!
The QS-G12M25 Greenback pack (v1) was originally created as part of the Van Halen 1984 Producer Series project, featuring specific vintage equipment, saturation, and breakup required to match the sound of that iconic recording.
Since then, we have created and standardised Neutron Quantum Speaker as a full range of packs with a common design language and characteristics, making them as versatile as possible. To bring the Greenback in line with these new standards, we decided to create QS-G12M25v2. This version captures the natural sound of the Greenback with a cleaner, more modern signal path, aligning it with the rest of the Quantum Speaker range.
