Plugin Boutique has launched a limited-time promotion to mark the addition of Quantum DSP to its store. The sale offers up to 80% off select products and runs until April 14th, 2026.

The Q-Series plug-and-play amps provide raw, responsive guitar tones without requiring extensive tweaking. Hybrid IR™️Libraries included with the plugins deliver mix-ready cabinet simulations drawn from rock and metal eras. These tools suit guitarists and producers focused on rock and metal production.

This introductory deal provides substantial discounts on new arrivals from Quantum DSP, making high-quality amp simulations accessible at reduced prices.

Individual plugins are on sale for $29.99 USD each. Invader captures vintage crunch, unfiltered ’90s grit, and modern punch.

Carnage focuses on precision and power through its unique high-gain sound. Both plugins support VST3, AU, and AAX formats on Windows and macOS.

The Q-Series Invader Carnage Bundle includes both plugins, plus Metal Mayhem Vol. 2 and Hard Rock Heroes Vol. 2 libraries. It is priced at $49.99 USD during the promotion.

Users can access these products directly through Plugin Boutique’s platform. The bundle combines amp emulations and IR libraries for comprehensive guitar processing in a DAW environment.
