CT-Bogna412V30T75-7B.wav

Inspired by Bogner® 4x12

Name decoding:

  • CT → Choptones
  • Bogna → reference to Bogner-style cabinet
  • 412 → checkout 4x12”
  • 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

Gain (dB)

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

HiCut (Hz)

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

LoCut (Hz)

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”

Mix (%)

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
