Barber Zero Amp Pack for Headrush Pedalboard, Gigboard, MX5, Prime, Core and Flex Prime Barber Zero Amp Pack – Italian Precision. Pure Overdrive Power. Choptones proudly presents the Barber Zero Amp Pack, a handcrafted tone experience inspired by the boutique firepower of the Mezzabarba M-Zero Overdrive. Designed and built in Italy with obsessive attention to sonic detail, the M-Zero delivers a bold, modern high-gain voice that’s both brutally articulate and deeply musical. With multiple gain structures—from its touch-sensitive drive channel to the face-melting overdrive mode—the M-Zero is a masterclass in boutique amp engineering. Known for its ultra-fast tracking, harmonic richness, and studio-grade clarity, it’s a go-to choice for modern rock, prog, and metal players who demand both character and control. Now, with the Barber Zero Amp Pack, that unique Italian tone is available for your digital rig. This pack includes 25 expertly crafted patches and 25 matching IRs, offering a complete journey through the M-Zero’s tone spectrum—from focused rhythm crunch to saturated, soaring leads. Throughout the profiling process, we explored every gain stage, including Drive, +Boost, and Overdrive modes—often enhanced with legendary boosts like the MXR 5150 OD, Mesa Grid Slammer, MXR Wylde OD, Ibanez TS808, and Boss SD1 TS808 Mod, unleashing even more punch and aggression. Cabs used include Marshall JH, 1960, Mesa Boogie 4x12 and 2x12, Peavey Invective, EVH, and Mezzabarba’s own Zeta 2x12, loaded with Celestion V30, G12M, G12M20, and G12EVH speakers. Mic setups featuring the SM57, MD421, e609, M201, and R121 were meticulously blended to preserve the amp’s dimensional tone and percussive response.
