- V30T75 → speaker mix:
- Celestion Vintage 30 (V30) → aggressive mids
- Celestion G12T-75 (T75) → more extended lows + brighter highs
- 7B → IR variant (mic position / blend / distance)
Sound character
This IR is very complex and professional:
- low deep but wider (T75)
- aggressive mids (V30)
- higher more extensive
- broad and modern response
Result: big, modern, wide and articulate sound
Perfect for:
- modern metal
- hard rock
- djent “wide”
- stereo rhythms
- recordings multi-layer
Recommended Parameters
IR level
Very powerful IR → pay attention to the level
Examples:
- Rock: -6 dB
- Metal: -8 dB
- Djent: -9 / -11 dB
Rule: lower to avoid muddy bass
Cuts high frequencies
presence of T75 → more extended highs → harsh risk
Realistic range:
- 6 kHz → 8.5 kHz
Examples:
- Rock: 6.5 kHz
- Metal: 7–7.5 kHz
- Djent: 7.5–8 kHz
Rule: Check the treble of the T75
Cuts low frequencies
wider bass (T75) → CRUCIAL parameter
Realistic range:
- 100Hz → 150Hz
Examples:
- Rock: 110 Hz
- Metal: 120–130 Hz
- Djent: 130–150 Hz
Rule: more LoCut = tighter less LoCut = more “wall”
Blend IR / dry
Standard:
- 100%
Creative:
- 80–90% for ambient
Pro Tips
Great starting point:
- Gain: -8 dB
- HiCut: 7 kHz
- LoCut: 120–130 Hz
- Mixes: 100%
This IR is ideal for:
stereo tracking double guitars modern “big” sounds
If it is too “wide”: raise LoCut lower HiCut
CT-Bogna412V30T75-7B is perfect:
as main IR for modern metal for hi-fi productions in combination with more mid IR (pure V30) for powerful live performances
