Description
The Mr Sparkle Buffer from Wasabi Effects is a high-fidelity input buffer and signal conditioner, designed to preserve the clarity, dynamics, and response of your guitar signal. Whether you’re running long cable runs, multiple pedals, or vintage fuzz circuits that react poorly to buffers, the Mr Sparkle ensures your tone remains pristine, punchy, and responsive.
Why You Need Mr Sparkle:
Even a few true-bypass pedals and long cables can darken your tone, reduce clarity, and kill dynamics. Traditional buffers help, but they often colour your sound in unwanted ways. The Mr Sparkle Buffer goes beyond a standard buffer, acting as a studio-grade signal amplifier to maintain the natural feel and chime of your guitar.
Features & Controls:
• Enhanced Unity Gain Buffer – Restores lost high-end and dynamics while keeping your tone natural.
• Three Sweetening Circuits – Toggle between subtle tonal enhancements:
- Harmonics (H): Adds air and presence for a tube-like chime.
- Bright (B): Restores lost high frequencies for a crisp, articulate tone.
- Low (L): Slightly boosts the low-end for added warmth and depth.
• Ultra-High Headroom – Handles high-output pickups and aggressive playing without distortion or compression.
• Flat Frequency Response – Maintains your guitar’s natural EQ balance with no unwanted coloration.
Built for the Modern Pedalboard:
• Runs on standard 9V DC (centre negative) power.
• Compact, top-mounted jacks for space-saving pedalboard integration.
• True bypass when disengaged
• Studio-quality components for ultra-low noise and maximum signal integrity.
Plug the Mr Sparkle Buffer in at the front of your signal chain and experience increased clarity, dynamic response, and a more articulate sound—all without sacrificing the warmth and feel of your guitar.
