The AmpKnob BDH bundle features three distinct high-gain guitar amplifiers inspired by iconic models cherished by heavy metal and metalcore artists. The BDH 5169 captures the aggressive and punchy tone of a classic 1992 block letter amp head, renowned for setting the standard in high-gain sound. The BDH 66o6+ offers a unique character with its heavily modified design, delivering a raw, dynamic response that stands apart from typical modern distortion tones. Meanwhile, the BDH III provides a rich and full distortion suited for both powerful riffs and smooth lead lines, drawn from Jens Bogren's personal amp collection and studio experience.

Each amplifier in the BDH series includes a built-in pedal switch that tightens the low end and increases input gain, perfect for adding extra drive to your riffs. The standalone version enhances creativity and workflow by offering an integrated recording function, allowing quick capture of ideas without needing to launch a full digital audio workstation. Additionally, the inclusion of a metronome and an accurate tuner supports musicians in maintaining timing and tuning during practice or recording sessions.

The tone is refined with carefully selected speaker cabinets, microphones, and recording chains, all overseen by producer Jens Bogren to ensure exceptional sonic detail. Users can disable the cabinet simulation or load custom impulse responses to tailor the sound further. This combination of authentic amp tones, practical features, and flexible sound shaping makes the AmpKnob BDH collection a compelling choice for guitarists seeking powerful high-gain amplification with studio-quality options.
