B-Box HG-2 Tube Saturation Profiles for NAM (Updated)

B-Box HG-2 Tube Saturation

Harmonic control. Tube color. Mix-ready depth.

The HG-2 is not just about warmth — it’s about shaping tone with intention.

By blending triode and pentode saturation, it allows you to dial in subtle enhancement or bold harmonic character, adding depth, presence, and cohesion to your mix.

Now updated with independently captured Left and Right channel profiles for authentic True Stereo operation using TSC Rack’s L/R Split mode.

Experience These Profiles with TSC Rack

To get the most out of these profiles, we recommend using TSC Rack — our original plugin designed specifically for Tokyo Studio Capture profiles.

TSC Rack fully supports the latest NAM A2 architecture, delivering the highest level of accuracy currently available, while also providing seamless True Stereo operation through independent Left and Right profile loading.

With its integrated profile browser, four processing slots, Auto Phase Calibration, Native Sample Rate Processing, and automatic profile management, TSC Rack makes working with NAM faster, simpler, and more enjoyable than ever.

True Stereo Operation

The original hardware features independently operating channels, each with its own unique analog behavior and subtle sonic characteristics.

To preserve this authenticity, every profile pair was captured independently from each channel of the original hardware.

Unlike conventional stereo processing, the Left and Right channels are not duplicated. Each profile retains its own unique analog fingerprint, closely reflecting the behavior of the original unit.

For the intended experience, load the matching CH1 and CH2 profiles using TSC Rack’s L/R Split mode. This preserves the natural depth, width, and dimensionality of the original hardware.

Sound Characteristics

• Harmonics can be shaped from subtle to aggressive
• Low-end gains density without losing clarity
• Highs can be smoothed or enhanced depending on the mode

Audio Demo

Compare the original hardware signal and the NAM profile across a range of sources — bass, guitar, synth, and more.
Each example demonstrates how closely the profile captures the tone, dynamics, and harmonic response of the hardware.
The NAM and hardware samples are gain-matched to allow for a more accurate evaluation of the capture’s fidelity.
For additional context, a dry (unprocessed) version is also included.

Why this capture is different

• Multiple tube saturation styles captured
• Carefully controlled drive levels during profiling
• Designed for mix bus and creative saturation workflows

Waveform Comparison (Hardware vs NAM)

Below is a direct comparison between the original hardware signal and the NAM profile output.
This visualization highlights how accurately the harmonic shaping and response are preserved.

Technical notes

• Format: NAM (.nam)
• Sample Rate: 48kHz
• Capture Type: Real hardware
• Calibration: Studio-level gain staging

Gain Staging Advice

Our captures are pre-calibrated at -18 dBFS input level.
For best results, we recommend feeding the plugin with an input signal close to -18 dBFS.

Due to gain reduction during the profiling process, the output level of a loaded profile may be slightly lower than the original input signal.

Please adjust the Output control to match your source level or to reach your preferred listening volume.
