The publisher identifies this recording as Fender Telecaster, bridge pickup,
maximum tone and volume. Excerpt: 00:24–00:36. Resampled to 48 kHz, short fades,
two seconds of tail space, then rendered through the saved presets.
The performance and these audio adaptations are supplied under GPL-3.0;
see GuitarML-LICENSE.txt. The prepared source excerpt is guitar-source-20260908.wav.
Offline rendering source: render-presets.cpp and preset-settings-20260908.json.
These audio files are separate assets; their license does not change the
Workshop application or the user's pedal recipes.

Preset processing: Tonewedge's existing native DSP implementation, NAM Core,
factory calibration trims, actual cabinet processing, and saved preset values
read from the device on 8 September 2026. No audio settings on the device were changed.
Lemon Glass: Lemon Pure, G12-65/DYN57 cabinet, Touch Comp, EQ, gate and reverb.
Iron Rhythm: Blackgate Rhythm, V30/SM57 Edge cabinet, Iron Law, EQ and gate.
Outputs were balanced to approximately -22 dBFS RMS, with peak headroom,
and encoded as 192 kbps MP3 for browser playback.

NAM model creators: siamsiamguite (Lemon Pure), ripper (Blackgate Rhythm),
and hblu2024 (Iron Law / Precision Drive HB Core Punch).

Only rendered musical recordings are published here. The NAM capture data
and cabinet impulse files are not redistributed.

Signal order in Workshop: recorded preset -> the user's Workshop blocks -> output.
The presets are audio recordings, not browser amp models. An editable block
therefore acts after the recorded amp/cabinet sound in this mode.

Long Workshop previews, 8 September 2026:
lemon-glass-long-20260908.mp3 and iron-rhythm-long-20260908.mp3 use
00:12–01:21.72 of the same licensed original performance (69.72 seconds), followed
by four seconds of native preset decay. Prepared source:
guitar-source-long-20260908.wav. The same offline renderer and saved preset
values above are used. Browser playback carries those four seconds of native decay over the next
phrase, with a 20 ms crossfade at the seam. Workshop reverb and delay state
is preserved on repeat.
Generated melody/chords now have six varied phrases across 48 seconds.

Long previews are matched to -26.2 dBFS RMS with at least 3 dB peak headroom.

9 September 2026 — Dry guitar audition
Dry guitar uses 00:24–01:28 of the same Keith Bloemer / GuitarML input
recording (guitar-di-original.wav in the rendering workspace). No amplifier,
cabinet, or effect processing is applied. Resampled to mono 48 kHz with brief
edge fades and encoded as 192 kbps MP3; the player makes an 80 ms seamless
loop overlap. Supplied under the same GPL-3.0 license above.
