Headway EDB-2 VAP Acoustic Preamp – Valve Alchemy Professional

Serious Equipment for Serious Musicians

The Headway EDB-2 VAP (Equaliser Direct Blender – Valve Alchemy Professional) represents the ultimate evolution of Headway’s acclaimed acoustic preamp range. Designed for professional musicians, this dual-channel acoustic preamp and harmonic enhancer delivers exceptional tone shaping, connectivity, and control.

Building on the highly regarded EDB-2 H.E, the VAP version introduces a powerful blendable valve (tube) stage into the signal path, adding warmth, depth, and rich harmonic character to your acoustic tone.

Valve Tone That Transforms Your Sound

The integrated valve circuit enhances your signal with natural compression, warmth, and musical harmonics. It helps eliminate the harsh “quack” often associated with piezo pickups, giving your acoustic instrument a more organic and studio-quality sound.

This makes the EDB-2 VAP ideal for performers seeking a more natural, mic-like tone from their pickup systems.

Dual Harmonic Enhancement System

The EDB-2 VAP features Dual Harmonic Enhancer technology, combining:

• Valve-based “Rich Harmonics” for warmth and body
• Analog “High Harmonics” (H.E.A.T.) for clarity and presence

This combination allows you to sculpt a tone that sits perfectly in both live and studio mixes.

Professional Dual-Channel Flexibility

The dual-channel design allows you to blend two sound sources, such as:

• Pickup + microphone
• Two pickups
• Two microphones

Each channel features independent EQ, gain structure, and impedance control, ensuring optimal performance with any instrument setup.

Advanced Tone Shaping and Feedback Control

The EDB-2 VAP provides two independent 5-band interactive EQ sections for precise tone shaping. Combined with advanced anti-feedback tools, it gives you full control in any performance environment.

• Tuneable notch filter
• Phase reverse switch
• Variable high-pass filter (“Range” control)

Designed for the Professional Stage

With dual balanced XLR DI outputs, phantom power options, and flexible routing, the EDB-2 VAP integrates seamlessly into any live or studio setup.

The inclusion of a USB charging port adds convenience for modern performers, allowing devices to be powered during gigs or sessions.
