Blammo Zap Master

Vintage Vibes, Modern Upgrades: The ZAP Master takes the classic Dallas Rangemaster treble boost circuit and gives it a BLAMMO! twist. It's designed to capture the essence of the original while adding modern enhancements for a superior boost experience. With top-mounted jacks and a pedalboard-friendly enclosure, it's both practical and tone-rich.

Enhanced Performance: This treble booster packs some impressive upgrades. It features a robust power filtering section with reverse polarity protection, ensuring your main circuit is safeguarded even if you accidentally use the wrong power supply. Metal film resistors reduce the noise floor, minimizing hiss and hum. The 3-way input cap switch offers tonal flexibility, allowing you to choose between the stock 5nf value and two additional mod values for added bass presence. Plus, with an NPN transistor, powering and daisy-chaining with other pedals becomes a breeze. The ZAP Master also provides a slight output volume boost, making it easy to push clean tube amps into natural overdrive or give fuzzy pedals a kick.
