Silverfish Dirty-Blues / Clean Switchable Bullet Harmonica Mic – handmade dual-element harp mic for versatile tone
The Silverfish Dirty-Blues / Clean Switchable Bullet Mic is a handmade, professional-grade harmonica microphone designed for players who demand two mics in one. Built with rugged all-metal construction, a dark hardwood fascia, compact volume control, and terminal-facing jack socket, it houses two separate dynamic elements—allowing you to switch instantly between gritty high-impedance “dirty” blues tone and crisp medium-impedance “clean” tone at the flip of a discreet brass micro-switch.
This unique dual-element design—likely the only one of its kind—delivers unmatched flexibility for stage and studio. Whether you’re chasing fat, overdriven Chicago crunch or articulate, top-end clarity, the Switchable Bullet Mic has you covered.
Design & Performance Highlights: two mics in one
Dirty-Blues, clean and “switchable” with dirty-blues and clean elements in one mic
Clean Dynamic Element (Medium 4KΩ Impedance)
-
Tone: Rich, articulate sound with enhanced top-end clarity and the widest frequency range in the Silver Bullet lineup
-
Performance: Lower sensitivity and higher headroom than high-Z models—ideal for clean blues, melody, country, funk, reggae, soul, or chromatic harmonica
-
Versatility: Adjust cupping for subtle clean effects, or add gain and reverb for gentle breakup
Dirty-Blues / Lo-Fi Dynamic Element (High 50KΩ Impedance)
-
Tone: Hot signal with full harmonic overtones, strong bass, warm mids, and smooth treble roll-off
-
Performance: High sensitivity and lower headroom for authentic dirty-blues distortion—responsive to cupping and pressure for gritty, low-fi Chicago blues tone
-
Versatility: Crank the gain with reverb for everything from subtle growl to fat, overdriven crunch
Ergonomic & Performance-Ready
-
Compact size – smaller than a Marine Band harmonica for easy airtight cupping
-
Rubber O-ring and knurled head ring – secure grip, even with sweaty hands
-
Firm volume knob – prevents accidental changes mid-performance
-
Near-silent switching – small brass micro-switch for clean/dirty element changes
-
Shock-mount design – reduces handling noise
-
Two-stage mesh & foam – minimizes breath noise for cleaner amplification

Why This Mic Stands Out
If you’re a harmonica player who switches between clean and dirty tones mid-set—or wants the freedom to experiment without swapping mics—this is your one-mic solution. From delicate, articulate melody lines to deep, gritty Chicago growl, the Silverfish Switchable Bullet Mic delivers it all in one beautifully crafted, small and lightweight powerhouse.
