Description

A custom-engineered, fully playable acoustic enclosure designed for the Fender Blues Deluxe 10-hole diatonic harmonica.

This silencer creates a miniature acoustic labyrinth directly behind the harmonica while leaving the entire metal mouthpiece exposed through a smooth, continuous lip opening. You can play normally—including bends and fast sweeps—without any rigid plastic interfering with your embouchure.

Acoustic Architecture

  • Direct Lip Access: A 94x9mm heavily rounded opening lets you play directly on the harmonica's surface.
  • Three-Chamber Labyrinth: Sound exiting the back of the harmonica is forced through a tortuous path (Chamber 1 → 90° split → Chamber 2 → Chamber 3) before reaching the external exhaust vents.
  • Foam-Ready: Generous internal tolerances (up to 4mm) on the back wall and first baffle allow for the manual installation of standard acoustic foam.
  • Vibration Isolation: The harmonica is held precisely in place by six tiny internal ribs with a calibrated 0.4mm clearance, eliminating rattle without clamping the instrument.
  • Tool-Free Assembly: Six internal cantilever snap-fits lock the top and bottom shells securely together and can be separated by hand.
