Sound character
This IR is very “pro studio”:
- low deep but controlled
- rich and present media
- soft but detailed tops
- wide and natural response
Result: hi-fi, full, very realistic sound
Perfect for:
- bass (all styles)
- slap
- funk
- clean modern guitar
- direct recording
Recommended Parameters
Gain (dB)
IR level
Very full IR → pay attention to gain
Examples:
- Bass: -5 dB
- Clean guitar: -4 dB
- Funk: -5 / -6 dB
Rule: avoid saturation on the low end
HiCut (Hz)
Cuts high frequencies
U47 → highs already soft but extended
Realistic range:
- 5 kHz → 8 kHz
Examples:
- Bass: 5.5–6 kHz
- Slap: 6.5–7.5 kHz
- Clean: 6–7 kHz
Rule: Control brilliance without losing detail
LoCut (Hz)
Cuts low frequencies
deep bass → CRUCIAL parameter
Realistic range:
- 60Hz → 100Hz
Examples:
- Bass: 60–70 Hz
- Funk: 70–80 Hz
- Clean guitar: 80–90 Hz
Rule: Check the low-end without emptying
Mix (%)
Blend IR / dry
Standard:
- 100%
Creative:
- 70–90% for parallel tone
Pro Tips
Great starting point:
- Gain: -5 dB
- HiCut: 6–6.5 kHz
- LoCut: 70–80 Hz
- Mixes: 100%
This IR is:
very “full range” very natural perfect for recording
if too “big”: raise LoCut lower Gain
