Headrush Impulse Responses
Whitemoon112OB
Inspired by Blackstar® 1x12 (Open Back)
Interpretation:
- Whitemoon → modern boutique cab/voicing (Friedman style / Full Moon vibe)
- 112 → checkout 1x12”
- OB (Open Back) → open back
Sound character
Compared to the C version (closed back):
- more air and space
- less compressed bass
- more "breathable" mids
- higher sweeter
Result: open, three-dimensional, natural sound
Perfect for:
- clean modern
- dynamic crunch
- fusion
- ambient
- natural recordings
Recommended Parameters
Gain (dB)
IR level
Open back = less compression → more dynamic
Examples:
- Clean: -3 dB
- Crunches: -4 / -5 dB
- Leads: -5 / -6 dB
Rule: leave headroom to maintain naturalness
HiCut (Hz)
Cuts high frequencies
Open IR → highs already soft but present
Realistic range:
- 5.5 kHz → 8 kHz
Examples:
- Clean: 6 kHz
- Crunches: 6.5–7 kHz
- Environment: 6–6.5 kHz
Rule: too loud = too bright sound too quiet = you lose air
LoCut (Hz)
Cuts low frequencies
Open back → less controlled bass
Realistic range:
- 80Hz → 130Hz
Examples:
- Clean: 85 Hz
- Crunches: 95–100 Hz
- Environment: 90 Hz
Rule: fundamental to avoid “flubby” sound
Mix (%)
Blend IR / dry
Standard:
- 100%
Creative:
- 80–90% for ambient sounds
Pro Tips
Great starting point:
- Gain: -4 dB
- HiCut: 6.5 kHz
- LoCut: 90–100 Hz
- Mixes: 100%
If the sound is:
- too “loose” → raise LoCut
- too “dark” → turn up HiCut
- too compressed → lower Gain
- not very “amp-like” → lowers LoCut slightly
Whitemoon112OB is perfect:
in stereo with a 112C for “amp in the room” sounds with delay and reverb for natural recording
