200ms → Most devices don't need more than 200ms, so this is fine to start with. 500ms → Longer recording with more natural reverb. Good for BOSS, Iridium, and software apps.
Most devices only use about 21-46ms. If you choose longer IR data (like 500ms), your device will automatically cut it to the right length.
• Sample Rate
Use 96kHz, 48kHz, or 44.1kHz folder to match your device.
• File Type
RAW: Natural sound response (recommended). *All files without "RAW" in the name are still RAW except MPT. MPT: Minimum Phase Transform - Phase-aligned IRs for mixing different cabinets
This IR was created using a rare 1967 Marshall™ 1960A cabinet with its iconic pinstripe grille cloth, paired with the highly regarded Celestion™ G12M20 Greenback Pre-Rola (ceramic magnet, 20W).
The G12M20 Pre-Rola was produced in the mid-1960s, and well-preserved original units have become increasingly difficult to find, making them highly sought after by collectors. Its tone embodies the character that defined the classic British sound of that era.
For this IR, the focus was on capturing the natural midrange weight, warmth, and responsiveness that this cabinet and speaker deliver. With carefully selected microphones and mic positions, the recording preserves as much of the vintage character and nuance of the original unit as possible.
Load it into your IR-compatible hardware or plugins to add the depth and presence of a genuine vintage rig to your sound.
